The U-joint cross runs on needle rollers in precision-ground bearing cups; when the EP grease film between the needle rollers and the cup surface breaks down, the contact mode shifts from rolling to boundary lubrication within minutes and to dry metal-on-metal contact shortly after. At 1000 RPM, that transition from lubricated to dry running takes the cross from normal fatigue life to acute failure in a fraction of a single operating shift.<\/p>\n<p>This guide covers every lubrication point on a round baler PTO shaft \u2014 the U-joint crosses, the telescoping tube spline profile, and where relevant the slip clutch bearing \u2014 along with the correct grease specification for each, the interval that matches the expected operating conditions, and the quantity indicators that confirm grease has reached the needle roller contact surfaces. The guidance applies to Series 4, 6, and 8 shafts across the main baler platforms used globally: John Deere, CASE IH, Krone, and New Holland round balers.<\/p>\n<\/div>\n<p><!-- IMAGE 1 --><\/p>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; text-align: center; padding: 28px 24px 0; box-sizing: border-box;\"><img decoding=\"async\" style=\"width: 100%; max-width: 100%; min-width: 100%; display: block; height: auto;\" src=\"https:\/\/superiortransmissioninc.com\/wp-content\/uploads\/2026\/07\/superiortransmissioninc-products-EP-Round-Baler-PTO-Shaft-for-John-Deere-469-569-Series-show.webp\" alt=\"EP Round Baler PTO Shaft for John Deere 469 569 Series lubrication point detail\" title=\"\"><\/div>\n<p><!-- SECTION 1: WHY GREASE MATTERS SO MUCH --><\/p>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; padding: 36px 24px 0; box-sizing: border-box;\">\n<h2 style=\"color: #1a3a52; border-left: 4px solid #2a5c70; padding-left: 14px; margin-top: 0;\">Why Lubrication Is the Primary Determinant of Cross Kit Service Life<\/h2>\n<p>Every U-joint cross in a round baler PTO shaft operates under a combination of torque load and angular deflection that places the needle rollers in the bearing cups under significant Hertzian contact stress. The grease film between the needle roller surface and the cup bore is the only element separating rolling contact from surface-to-surface metal contact. This film is typically between 0.5 and 2 micrometres thick \u2014 thinner than a human hair \u2014 and it depends entirely on fresh grease being pumped through the cross body channel to each cup at regular intervals. When the film breaks down, the needle rollers begin to pit and the cup bore surface begins to spall. Both processes are self-accelerating: damaged surfaces generate abrasive debris that reduces the contact area, raises the local stress, and accelerates further damage.<\/p>\n<p>The critical point for a round baler PTO shaft operating at 1000 RPM is the sheer speed at which lubricant breakdown translates to component damage. At 1000 RPM the cross completes approximately 16 full bending cycles per second \u2014 and each revolution with a dry or degraded grease film deposits a small amount of wear debris in the cup. A cross that runs for two hours with a failed grease film in silage conditions \u2014 where water contamination is washing fresh grease away through the seals \u2014 can accumulate enough cup bore damage to require kit replacement before the end of the cutting shift. Greasing at the correct interval is not optional maintenance; it is the operational variable that most directly determines whether a cross kit lasts one season or four months.<\/p>\n<\/div>\n<p><!-- SECTION 2: MANUFACTURING CONSTRUCTION \u2014 GREASE PATHS --><\/p>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; padding: 32px 24px 0; box-sizing: border-box;\">\n<h2 style=\"color: #1a3a52; border-left: 4px solid #2a5c70; padding-left: 14px; margin-top: 0;\">Manufacturing Construction: Grease Paths Through the Cross Body<\/h2>\n<p>Understanding the physical path that grease takes from the nipple to the needle roller contact zone helps operators confirm that their greasing is actually reaching the right location \u2014 not just filling the cross body cavity without reaching the cups. In a standard agricultural series cross, the grease nipple is threaded into a port at the centre of the cross body \u2014 accessible on one face of the cross without removing the guard. When the grease gun is applied to this nipple, grease flows from the nipple bore into an internal channel that runs through the cross body to each of the four trunnion bases. From the trunnion base, grease enters the cup cavity through the clearance between the trunnion surface and the inner face of the cup, distributing along the needle roller length via the rolling action of the needles.<\/p>\n<p>The seal at each cup end \u2014 a lip seal or triple-lip seal in quality kits \u2014 retains the grease in the cup cavity and excludes water and crop debris. The grease distribution path is correct when fresh grease appears at the outside lip of each seal face during greasing \u2014 this confirms that grease has reached the far end of each cup and that the path through the cross body is clear. If grease does not appear at one or more seal faces after a standard greasing cycle, that cup&#8217;s channel is blocked \u2014 typically by hardened old grease from a previous season&#8217;s accumulation inside the cross body bore \u2014 and the cross must be removed, cleaned, and re-greased or replaced. A blocked channel produces a dry cup even when the operator has applied grease through the nipple, which is why a cross that was greased on schedule can still fail if the internal path has silted up.<\/p>\n<\/div>\n<p><!-- SECTION 3: MATERIAL SYSTEM \u2014 GREASE SPECIFICATION --><\/p>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; padding: 32px 24px 0; box-sizing: border-box;\">\n<h2 style=\"color: #1a3a52; border-left: 4px solid #2a5c70; padding-left: 14px; margin-top: 0;\">Grease Specification: What to Use at Each Lubrication Point<\/h2>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; overflow-x: auto; -webkit-overflow-scrolling: touch; box-sizing: border-box;\">\n<table style=\"width: 100%; max-width: 100%; min-width: 100%; border-collapse: collapse;\">\n<thead>\n<tr style=\"background: #1a3a52; color: #ffffff;\">\n<th style=\"padding: 12px 16px; text-align: left; white-space: nowrap;\">Lubrication Point<\/th>\n<th style=\"padding: 12px 16px; text-align: left; white-space: nowrap;\">Recommended Grease Type<\/th>\n<th style=\"padding: 12px 16px; text-align: left; white-space: nowrap;\">NLGI Grade<\/th>\n<th style=\"padding: 12px 16px; text-align: left; white-space: nowrap;\">Base Oil Viscosity<\/th>\n<th style=\"padding: 12px 16px; text-align: left; white-space: nowrap;\">Notes<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr style=\"border-bottom: 1px solid #b0ccd8; background: #eaf3f8;\">\n<td style=\"padding: 11px 16px;\">U-joint cross and bearing cups<\/td>\n<td style=\"padding: 11px 16px;\">EP2 lithium complex<\/td>\n<td style=\"padding: 11px 16px;\">2<\/td>\n<td style=\"padding: 11px 16px;\">200 cSt min at 40\u00b0C<\/td>\n<td style=\"padding: 11px 16px;\">Water-resistant; compatible with NBR seals<\/td>\n<\/tr>\n<tr style=\"border-bottom: 1px solid #b0ccd8;\">\n<td style=\"padding: 11px 16px;\">Telescoping tube splines<\/td>\n<td style=\"padding: 11px 16px;\">EP2 lithium complex<\/td>\n<td style=\"padding: 11px 16px;\">2<\/td>\n<td style=\"padding: 11px 16px;\">200 cSt min at 40\u00b0C<\/td>\n<td style=\"padding: 11px 16px;\">Spread evenly on spline profile; not excess-filled<\/td>\n<\/tr>\n<tr style=\"border-bottom: 1px solid #b0ccd8; background: #eaf3f8;\">\n<td style=\"padding: 11px 16px;\">CV joint head (wide-angle)<\/td>\n<td style=\"padding: 11px 16px;\">EP2 lithium complex or OEM-specified CV grease<\/td>\n<td style=\"padding: 11px 16px;\">2<\/td>\n<td style=\"padding: 11px 16px;\">150\u2013220 cSt at 40\u00b0C<\/td>\n<td style=\"padding: 11px 16px;\">Check OEM spec \u2014 some CV heads require molybdenum-fortified grease<\/td>\n<\/tr>\n<tr style=\"border-bottom: 1px solid #b0ccd8;\">\n<td style=\"padding: 11px 16px;\">Lockback collar mechanism<\/td>\n<td style=\"padding: 11px 16px;\">Light machine oil or EP1 grease<\/td>\n<td style=\"padding: 11px 16px;\">0\u20131<\/td>\n<td style=\"padding: 11px 16px;\">Low viscosity<\/td>\n<td style=\"padding: 11px 16px;\">Thin film only; excess attracts crop debris<\/td>\n<\/tr>\n<tr style=\"background: #eaf3f8;\">\n<td style=\"padding: 11px 16px;\">Guard bearing ring (where grease-able)<\/td>\n<td style=\"padding: 11px 16px;\">EP2 lithium complex or specified plastic-compatible grease<\/td>\n<td style=\"padding: 11px 16px;\">2<\/td>\n<td style=\"padding: 11px 16px;\">Standard agricultural<\/td>\n<td style=\"padding: 11px 16px;\">Some guard bearing rings are sealed and pre-filled for life<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p style=\"margin-top: 16px;\">The most critical specification at the U-joint cross is the grease&#8217;s compatibility with the seal material. Agricultural series cross seals are typically NBR (acrylonitrile-butadiene rubber).

Shafts with four individual nipples (one per cup) use the same procedure applied at each nipple rather than a single central nipple. Always grease with the shaft stationary and the tractor PTO disengaged.<\/p>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; background: #eaf3f8; border-left: 4px solid #2a5c70; padding: 20px 20px 20px 22px; box-sizing: border-box; border-radius: 0 4px 4px 0; margin-top: 8px;\">\n<p style=\"margin: 0 0 12px;\"><strong>Step 1 \u2014 Disengage the PTO and allow the shaft to stop completely.<\/strong> Greasing a rotating shaft is dangerous and ineffective; the centrifugal force disperses grease away from the needle roller contact zone. Confirm the shaft is stationary before approaching with the grease gun.<\/p>\n<p style=\"margin: 0 0 12px;\"><strong>Step 2 \u2014 Clean the grease nipple on the first cross with a rag.<\/strong> Applying the grease gun to a nipple covered in soil, crop debris, or hardened old grease pushes contamination directly into the cross body bore and the needle roller cavity. A five-second wipe of the nipple face before connecting the gun prevents the most common route of abrasive contamination into the cross.<\/p>\n<p style=\"margin: 0 0 12px;\"><strong>Step 3 \u2014 Attach the grease gun and pump slowly until fresh grease appears at all four seal faces.<\/strong> Pumping quickly generates excess pressure that ruptures the seals \u2014 particularly on worn or older seal kits \u2014 rather than distributing grease evenly through the cross. One slow stroke every two to three seconds is the appropriate rate. Stop pumping immediately when fresh grease is visible at all four seal lips; continuing to pump at that point has no additional benefit and forces grease behind the seal, washing out the old seal lip seal lubricant.<\/p>\n<p style=\"margin: 0 0 12px;\"><strong>Step 4 \u2014 If grease does not appear at one or more seal faces after six to eight pump strokes, flag that cross for inspection.<\/strong> A cup that is not receiving grease through the cross body channel has a blocked internal bore. Continuing to pump adds pressure without distributing lubrication to the blocked cup. Remove the shaft for cross cleaning or replacement before the next operating shift.<\/p>\n<p style=\"margin: 0 0 12px;\"><strong>Step 5 \u2014 Repeat for the second cross (at the implement end).<\/strong> Both crosses on the shaft are serviced at the same interval; skipping the implement-end cross because it is less accessible is a common error that produces asymmetric cross wear \u2014 with the implement-end cross failing first in nearly every case where this approach has been used.<\/p>\n<p style=\"margin: 0;\"><strong>Step 6 \u2014 Grease the telescoping tube splines.<\/strong> Retract the inner tube partially and apply a bead of EP2 grease to the visible spline profile along its full accessible length. Extend the shaft fully and compress it again to distribute the grease across the contact zone. This step is frequently omitted in field service because the guard makes the splines visually inaccessible; the guard must be slid back to access the spline end before greasing.<\/p>\n<\/div>\n<\/div>\n<p><!-- PRODUCT CARD --><\/p>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; padding: 36px 24px 0; box-sizing: border-box;\">\n<h2 style=\"color: #1a3a52; border-left: 4px solid #2a5c70; padding-left: 14px; margin-top: 0;\">EP Round Baler PTO Shaft for Krone Round Balers \u2014 Triple-Lip Seal for Extended Grease Retention<\/h2>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; background: #eaf3f8; border: 1px solid #90bccf; border-radius: 6px; padding: 24px; box-sizing: border-box;\">\n<div style=\"display: flex; flex-wrap: wrap; gap: 20px; align-items: flex-start;\">\n<div style=\"flex: 0 0 auto; width: 180px; max-width: 100%;\"><a href=\"https:\/\/superiortransmissioninc.com\/fr\/produit\/ep-pto-shaft-for-krone-round-balers-round-baler-pto-shaft\/\"><br \/>\n<img decoding=\"async\" style=\"width: 100%; max-width: 100%; min-width: 100%; height: auto; display: block; border-radius: 4px;\" src=\"https:\/\/superiortransmissioninc.com\/wp-content\/uploads\/2026\/07\/superiortransmissioninc-products-EP-PTO-Shaft-for-Krone-Round-Balers-Round-Baler-PTO-Shaft-300x300.webp\" alt=\"EP PTO Shaft for Krone Round Balers\" title=\"\"><br \/>\n<\/a><\/div>\n<div style=\"flex: 1 1 220px;\">\n<h3 style=\"color: #1a3a52; margin: 0 0 10px;\"><a style=\"color: #1a3a52; text-decoration: none;\" href=\"https:\/\/superiortransmissioninc.com\/fr\/produit\/ep-pto-shaft-for-krone-round-balers-round-baler-pto-shaft\/\">EP PTO Shaft for Krone Round Balers<\/a><\/h3>\n<p style=\"margin: 0 0 12px;\">A direct-fit round baler PTO shaft replacement for Krone round baler platforms including the KR and Comprima series.

Water enters the cup through the seal during wet operations and displaces the grease film from the needle roller contact zone faster than in dry conditions. The confirmation check \u2014 fresh grease visible at all four seal faces after each greasing cycle \u2014 is especially important in these conditions because a cross that appears to have been greased may not have received a full charge if the internal bore has a partial blockage from old grease that water has emulsified and hardened. Using a triple-lip seal cross kit in wet silage operations extends the effective interval, but the 4\u20136 hour check remains the correct practice regardless of seal specification.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; border: 1px solid #90bccf; border-radius: 5px; margin-bottom: 10px; overflow: hidden; box-sizing: border-box;\">\n<details>\n<summary style=\"background: #eaf3f8; padding: 14px 18px; cursor: pointer; font-weight: bold; color: #1a3a52; list-style: none; width: 100%; max-width: 100%; min-width: 100%; box-sizing: border-box;\">What type of grease is best for a round baler PTO shaft used on a John Deere baler in hot, dry harvesting conditions in Australia or South Africa?<\/summary>\n<div style=\"padding: 16px 18px; background: #ffffff;\">\n<p style=\"margin: 0;\">In hot, dry harvesting conditions \u2014 Australian summer hay and straw baling above 35\u00b0C, or South African grain-belt operations \u2014 the grease&#8217;s thermal stability becomes the primary selection criterion alongside its EP performance. An EP2 lithium complex grease with a base oil viscosity of at least 200 cSt at 40\u00b0C and a dropping point above 260\u00b0C is the appropriate specification. Lithium complex greases retain their consistency and film thickness at elevated temperatures better than standard lithium soap greases, whose dropping point is typically 180\u2013200\u00b0C and which can thin significantly at sustained 40\u201350\u00b0C ambient temperatures in Australian and South African field conditions. The greasing interval should be shortened to every 6 hours in these conditions because elevated temperature accelerates base oil evaporation and grease oxidation, depleting the effective lubrication charge faster than the standard 8-hour interval assumes.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; border: 1px solid #90bccf; border-radius: 5px; margin-bottom: 10px; overflow: hidden; box-sizing: border-box;\">\n<details>\n<summary style=\"background: #eaf3f8; padding: 14px 18px; cursor: pointer; font-weight: bold; color: #1a3a52; list-style: none; width: 100%; max-width: 100%; min-width: 100%; box-sizing: border-box;\">Why does grease not come out of all four seal faces when I grease my round baler PTO shaft on a CASE IH baler in Canada \u2014 and what should I do?<\/summary>\n<div style=\"padding: 16px 18px; background: #ffffff;\">\n<p style=\"margin: 0;\">When grease appears at only one, two, or three of the four seal faces after a full greasing cycle, one or more of the internal channels through the cross body has a blockage \u2014 typically hardened old grease from a previous season that has formed a plug in the bore between the central channel and the trunnion base. This is a known issue on round baler PTO shaft crosses that have been in service for multiple seasons without a full cross kit replacement. The temporary field action is to apply additional slow pump strokes with the grease gun maintained on the nipple, which builds pressure behind the blockage and may clear it; if the cup remains ungretased after five to six additional strokes, mark the cross for removal and replacement before the next operating shift. Operating a CASE IH round baler with a dry cup on the implement-end cross \u2014 particularly in dense Prairie crop conditions \u2014 risks the cross fracturing within one to three hours of resuming baling. A cross kit replacement at this point costs significantly less than the yoke ear damage that follows if the cross fractures in service.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; border: 1px solid #90bccf; border-radius: 5px; margin-bottom: 10px; overflow: hidden; box-sizing: border-box;\">\n<details>\n<summary style=\"background: #eaf3f8; padding: 14px 18px; cursor: pointer; font-weight: bold; color: #1a3a52; list-style: none; width: 100%; max-width: 100%; min-width: 100%; box-sizing: border-box;\">How do I grease the telescoping tube splines on a round baler PTO shaft with a Krone baler in Germany when the guard makes the splines hard to reach?<\/summary>\n<div style=\"padding: 16px 18px; background: #ffffff;\">\n<p style=\"margin: 0;\">Greasing the telescoping tube splines on a Krone round baler PTO shaft requires sliding the guard tube back to expose the spline entry at the inner tube end \u2014 a step that is often skipped because it requires a few additional seconds to move the guard. With the PTO disengaged and the tractor stationary, slide the guard cone at the mid-point of the shaft along the guard tube toward the tractor end until the inner tube spline profile is visible at the implement end of the guard tube. Apply a bead of EP2 grease along the visible spline profile and work the shaft through its full extension range twice by hand to distribute the grease across the contact zone. Slide the guard cone back into its retention collar and confirm it seats correctly before resuming baling. In German operating conditions \u2014 where contour changes and headland angles on smaller parcels produce more telescoping cycles per operating hour than open prairie baling \u2014 the spline lubrication interval should be every 15 hours rather than the 20-hour dry-field standard.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<div style=\"width: 100%; max-width: 100%; min-width: 100%; border: 1px solid #90bccf; border-radius: 5px; margin-bottom: 10px; overflow: hidden; box-sizing: border-box;\">\n<details>\n<summary style=\"background: #eaf3f8; padding: 14px 18px; cursor: pointer; font-weight: bold; color: #1a3a52; list-style: none; width: 100%; max-width: 100%; min-width: 100%; box-sizing: border-box;\">What happens if I use multipurpose grease instead of lithium complex EP2 grease on a round baler PTO shaft used in New Zealand or Brazil?<\/summary>\n<div style=\"padding: 16px 18px; background: #ffffff;\">\n<p style=\"margin: 0;\">Using a calcium-soap multipurpose grease \u2014 the most commonly available all-purpose farm grease in New Zealand and Brazilian agricultural supply chains \u2014 on a round baler PTO shaft cross has two specific adverse effects. First, calcium-soap grease is not compatible with the NBR rubber seal compounds used in agricultural series cross kits; the calcium complex reacts with the NBR material over time, causing the seal to swell and harden. A swollen seal collapses against the trunnion, restricting the grease flow path from the cross body bore to the cup cavity and effectively sealing the cup against both new grease entry and water egress. Second, calcium-soap greases have a lower water resistance rating than lithium complex greases, making them especially unsuitable for the wet New Zealand ryegrass silage and the high-humidity Brazilian sugarcane baling environments. If the correct EP2 lithium complex grease is not available at the point of service, it is better to delay greasing until the correct product can be sourced than to apply an incompatible grease that will accelerate seal degradation.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<\/div>\n<\/div>\n<p style=\"text-align: right;\">\u00c9diteur : PXY<\/p>","protected":false},"excerpt":{"rendered":"<p>LUBRICATION BEST PRACTICE GUIDE A complete lubrication guide for round baler PTO shaft U-joint crosses, telescoping tube splines, and slip clutch components \u2014 covering grease specification, interval, quantity, and the field signs that tell you when the lubrication system has failed. \u00a0Round Baler PTO Shaft Greasing a round baler PTO shaft correctly is not complicated [&hellip;]<\/p>","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"categories":[69],"tags":[],"class_list":["post-2061","post","type-post","status-publish","format-standard","hentry","category-pto-shaft-for-round-baler"],"_links":{"self":[{"href":"https:\/\/superiortransmissioninc.com\/fr\/wp-json\/wp\/v2\/posts\/2061","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/superiortransmissioninc.com\/fr\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/superiortransmissioninc.com\/fr\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/superiortransmissioninc.com\/fr\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/superiortransmissioninc.com\/fr\/wp-json\/wp\/v2\/comments?post=2061"}],"version-history":[{"count":2,"href":"https:\/\/superiortransmissioninc.com\/fr\/wp-json\/wp\/v2\/posts\/2061\/revisions"}],"predecessor-version":[{"id":2063,"href":"https:\/\/superiortransmissioninc.com\/fr\/wp-json\/wp\/v2\/posts\/2061\/revisions\/2063"}],"wp:attachment":[{"href":"https:\/\/superiortransmissioninc.com\/fr\/wp-json\/wp\/v2\/media?parent=2061"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/superiortransmissioninc.com\/fr\/wp-json\/wp\/v2\/categories?post=2061"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/superiortransmissioninc.com\/fr\/wp-json\/wp\/v2\/tags?post=2061"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
