EP-120-140HP fyrkantsbalpress växellåda (EP-FK270)

1 · 1:1 Direct Drive — Drivetrain Simplicity

A 1:1 gear ratio eliminates the need for compensatory speed adjustments elsewhere in the baler's drivetrain. The PTO shaft runs at 540 r/min, and the baler drive shaft receives exactly 540 r/min — a configuration that simplifies knotter timing setup and reduces the number of variables when diagnosing bale density or tie-failure issues. Operators familiar with the baler's existing drive design benefit most: what they know about the machine at a given PTO speed still applies after fitting this new square baler gearbox.

2 · 140 hp Peak — Headroom for Dense Crop

With a nominal rating of 120 hp and a peak of 140 hp, the EP-FK270 carries a 16% power headroom above the working load. That margin may seem modest in percentage terms, but at 120 hp the absolute energy involved in a surge event is substantial. Dense alfalfa windrows and high-moisture barley straw both generate plunger-stall forces that can spike briefly to 140 hp — and a correctly rated square baler gearbox handles these events without tooth fatigue or oil film breakdown in the bearing raceway.

3 · Compact Proportions for Tight Frame Envelopes

The 208.0 mm housing face width and 270.0 mm depth give the EP-FK270 a lean profile that fits within the mounting envelopes common on mid-size square balers from major agricultural markets. The 4 × Ø17.0 mm base bolt pattern on a 294.0 × 118.8 mm footprint matches widely-used baler mounting flange standards, making this a practical choice when sourcing a kit square baler gearbox for a retrofit or refurbishment project without structural modification to the baler frame.

4 · Gleason Straight Teeth — Controlled Mesh Contact

The Gleason Straight Teeth profile produces predictable, measurable tooth contact patterns that can be inspected and documented. In agricultural settings where gearboxes work far from service centers, a tooth form that degrades gradually and predictably — rather than failing suddenly from fatigue micropitting — gives operators time to schedule maintenance. This characteristic makes the EP-FK270 a defensible choice for buyers sourcing agri supply square baler gearbox components who need documented, repeatable part quality across multiple units.

5 · Verified Under ISO 9001:2015 QMS

Every EP-FK270 exits the manufacturing process through a documented inspection sequence under an ISO 9001:2015 certified quality management system. Dimensional checks, tooth contact pattern verification, and a no-load run-in test are completed before packaging. For agricultural equipment distributors in markets like South Korea, Brazil, Canada, and the Netherlands where import documentation requirements include quality certificates, this certification removes a procurement barrier that informal suppliers cannot address.

Hus

Ductile iron (GGG50 / QT500-7 equivalent), cast to controlled wall thickness. Tensile strength significantly above grey iron grades, with crack-arrest properties that matter when inertia shocks propagate through the housing from sudden plunger-stall events during square baler operation.

Gear Set

20CrMnTi alloy steel, gas-carburized and case-hardened to HRC 58–62 at the tooth surface. Gleason Straight Teeth flanks finish-ground after heat treatment. Contact pattern inspected by CMM prior to assembly — a standard that separates manufactured-to-spec gear sets from machined-to-fit approximations.

Axlar

42CrMo4 alloy steel, quenched and tempered to 280–320 HB. Shaft journals ground to h6 tolerance for reliable bearing seat fit. Splined and keyed end configurations available to match the yoke standards used across major tractor and baler platforms in North American and European markets.

Lager

Heavy-duty tapered roller bearings, selected for combined radial and axial load capacity at 140 hp peak. Pre-assembled with precision spacers to maintain correct axial preload. Bearing bores machined after housing casting to maintain concentricity and ensure long-term shaft alignment.

Tätning

Double-lip NBR oil seals at both shaft exits, rated −20 °C to +125 °C. The double-lip design on the input shaft specifically addresses dust ingress from the baler's crop handling environment — a real-world failure mode on single-lip seals operating in wheat or straw dust during summer harvest.

Kvalitetscertifiering

ISO 9001:2015 certified manufacturing. Incoming material batch-tested for chemical composition and hardness. Finished units pass dimensional inspection, gear contact verification, and a documented no-load run-in test before dispatch. Test records available on request for commercial buyers.

Mid-Size Farm Hay Baling

Farm operations running 100–130 hp tractors across alfalfa, clover, and grass hay crops represent the primary market for the EP-FK270. At this scale, the baler runs 8–14 hours a day during peak cutting windows, and the gearbox must deliver consistent performance without requiring mid-season maintenance stops. The 140 hp peak rating absorbs the density spikes that humid early-cut alfalfa produces reliably, while the 1:1 ratio keeps knotter timing stable shift after shift — a practical benefit that experienced square baler pickup system operators recognize immediately.

Wheat & Rye Straw Recovery

Straw recovery post-harvest is an important secondary income stream for grain farms across North America, the UK, and European markets including the Netherlands and Germany. The EP-FK270 handles straw baling reliably at the 120 hp level where most mid-size square balers operate, delivering consistent torque transfer even when combine-cut straw creates uneven feed rates through the baler's crop intake and square baler pickup mechanism. Its direct-drive ratio means there is no cumulative slippage effect between bale cycles — each plunger stroke starts from the same baseline drive condition.

Refurbished Baler Fitment

A substantial share of square balers in active service globally are second or third-generation machines that have been overhauled and returned to operation. The EP-FK270's base footprint of 294.0 × 118.8 mm and 4 × Ø17.0 mm mounting bolt pattern match the frame geometry common on mid-size balers from the major manufacturers of the past two decades. For dealers and workshops sourcing a replacement square baler gearbox for refurbishment projects in Canada, Australia, and South Korea, this dimensional compatibility is a straightforward procurement advantage.

Specialty Crop Baling

Hemp stalk, switchgrass, and miscanthus baling for biomass and industrial fiber markets are growing applications for mid-size square balers. These crops vary widely in stem stiffness, moisture content, and bulk density. The EP-FK270's 140 hp peak tolerance and robust ductile iron housing provide the physical resilience to handle these materials without the constant monitoring that an undersized gearbox would demand from the operator. Users considering a square baler gearbox for sale for specialty-crop applications find this model covers the realistic load range of most mid-size baler configurations used in these markets.

Export-Market OEM Supply

Agricultural machinery manufacturers in Brazil, Colombia, and Southeast Asian markets who build mid-size square balers for regional distribution need a new square baler gearbox source with documented quality standards, repeatable dimensional tolerances, and reliable production capacity. The EP-FK270 satisfies these requirements under ISO 9001:2015, making it a practical OEM supply option. Custom shaft dimensions and OEM-neutral packaging are available for branded equipment programs where the original equipment identity needs to be preserved.

Kraftuttagsaxel för fyrkantspress

The EP-FK270's 540 r/min input shaft requires a PTO shaft rated for continuous 120 hp operation with a 140 hp surge capacity. Our square baler pto shaft lineup covers wide-angle configurations, shear-bolt overload protection, and friction-clutch variants across the full range of tractor hitch heights and PTO flange standards used in USA, Australian, and European markets. Compatibility data confirming yoke cross size, overall length, and torque rating is available for any specific tractor-baler combination.

Square Baler Machines

For buyers evaluating a complete baling system rather than individual components, our full series square baler range — including hammer-claw type machines with 2200 mm picking width — is manufactured to the same engineering standards as the EP-FK270 gearbox. Sourcing the machine and its drivetrain components from one manufacturing origin eliminates interface uncertainty on shaft diameters, yoke sizes, and frame mounting dimensions. This one-stop supply advantage is particularly valued by importers and distributors in the Netherlands, Canada, and South Korea who manage large equipment inventories across multiple end-user accounts.
