Description

Integrated disc harrow bearing hub 45 mm inner diameter - Part number 57244

Replacement integrated bearing hub unit for agricultural disc harrows and soil tillage equipment, commercial part number 57424. Engineered to house and protect internal bearing components while maintaining smooth gang axle rotation, it withstands heavy combined radial and axial loads. The sealed, heavy-duty housing shields rolling elements from dust, sand, mud, and moisture during aggressive field work. It features an internal bore diameter of 45 mm (dimension F), housing outer diameter of 97 mm (dimension A), 26 mm mounting pins, 114 mm hole-to-hole center distance (dimension C), 48.5 mm height (dimension D), and an overall length of 147 mm (dimension E).

Key features

Heavy-duty solid housingRugged cast construction engineered to absorb impacts, torsional shocks, and continuous vibrations from the disc gang.

Sealed protection systemHigh-performance sealing design that prevents abrasive dust, sludge, and crop debris from entering the internal bearing cavity.

26 mm mounting pinsHeavy-duty fastening design ensuring rigid, secure mounting to the harrow gang hanger brackets without mechanical play.

Calibrated mounting dimensions114 mm center distance with a 48.5 mm profile height and 147 mm overall length for standard OEM replacement fitment.

Precision 45 mm internal boreMachined bore for 45 mm shafts ensuring proper coaxial alignment, reduced friction, and balanced rotational operation.

Fitting tipsBefore installing the unit onto the harrow frame, clean the mounting hanger surfaces and shaft contact points thoroughly to remove rust, scale, and soil buildup. Align the hub with the frame brackets using the 114 mm center distance and insert the 26 mm mounting hardware smoothly without cross-binding. Slide the 45 mm gang axle through the unit, ensuring coaxial alignment to avoid premature bearing failure from uneven loading. Torque all frame mounting bolts to the manufacturer's recommended torque specifications, lubricate if greaseable, and recheck fastener tightness after the initial operational hours in the field.
