F-225036 Width - 27mm Needle Roller Bearing Hydraulic Pump Bearing

F-225036 is exclusive split crescent half-race drawn cup needle roller bearing matched for Rexroth A4TG71 axial piston hydraulic pump core rotary assembly Unlike full-circle integral needle bearings, it adopts semi-circular split outer race one-piece stamping forming structure, matched with dense cylindrical needle rollers and stamped steel retainer, perfectly fits the arc mounting cavity inside hydraulic pump housing, only bears heavy alternating radial load under long-term high-pressure hydraulic oil medium environment.

Whole bearing adopts integral GCr15 high-carbon chrome bearing steel, integral quenching and low-temperature tempering treatment, raceway ultra-precision mirror grinding to greatly improve anti-contact fatigue, anti-abrasion and hydraulic oil corrosion resistance. Semi-circular split design allows local disassembly and replacement without complete pump housing splitting, drastically shorten equipment maintenance downtime and reduce overhaul labor cost. Widely applied to Rexroth A4TG71 hydraulic main pump, excavator/loader road roller construction machinery hydraulic pump, industrial heavy hydraulic power unit and engineering vehicle hydraulic drive core wear parts.
