Rexroth Hydraulic Pump Bearing F-2603727 Width - 15.35mm Needle Bearing

F-2603727 is special split crescent half-race drawn cup needle roller bearing exclusively matched for Rexroth hydraulic main pump core assembly. Different from integral round needle bearings, it adopts semi-circular split outer race integral stamping structure, matched with dense cylindrical needle rollers and wear-resistant steel retainer, perfectly fits the arc mounting cavity inside hydraulic pump housing, only bears heavy radial alternating load under high-pressure oil medium environment.

The whole bearing is made of integral GCr15 bearing steel, overall quenching and low-temperature tempering treatment, surface ultra-precision grinding to improve anti-fatigue and oil corrosion resistance. Semi-circular split design greatly simplifies pump internal disassembly and maintenance without complete pump housing disassembly, effectively shortening equipment downtime. Widely used in Rexroth axial piston hydraulic pumps, construction machinery main hydraulic pumps, industrial hydraulic power units and heavy equipment hydraulic drive core components.
