INPUT SHAFT BEARING Parker Hydraulic gear Pump Parts

This high-precision input shaft cylindrical roller bearing is independently manufactured by RCHC, fully drop-in interchangeable with OEM bearings of Parker PGP030, PGP031, PGP050, PGP051, PGP075 and PGP076 hydraulic gear pumps, covering single pumps and piggyback tandem pump assemblies. Installed inside the shaft end cover on both ends of the drive input shaft, it serves as the core load-bearing component supporting the whole driving shaft, bearing heavy radial impact loads and minor axial force generated by PTO power transmission during heavy-duty operation.

RCHC strictly adopts high-chromium bearing steel with standardized quenching and tempering heat treatment. All inner race, outer race and cylindrical rollers are precision ground under micron-level tolerance, verified by professional gear measuring centers before delivery. Tight dimensional accuracy stabilizes shaft concentricity, effectively avoiding gear eccentric meshing, abnormal shaft seal abrasion, pump vibration and loud noise. Unlike thin needle roller bearings only for driven gears, this bearing balances high rotating speed and strong lo

ad capacity, adapting to frequent start-stop and vibration scenarios of dump trucks, loaders, tractors and sanitation vehicles.

All bearings run smoothly relying on internal hydraulic oil lubrication. Our rigorous quality inspection eliminates size deviation, extends bearing service life, stabilizes pump volumetric efficiency and cuts maintenance downtime. RCHC offers stable bulk supply, 12-month quality warranty and complete compatibility with Continental Type 7 long shafts and standard short shafts of PGP pumps for global aftermarket distributors and repair shops.
