F-845889 BR2565DTA2 Double Row Tapered Roller Bearing Automotive Differential

1. Product Overview

F-845889 equivalent BR2565DTA2 is integrated double row tapered roller bearing specially designed for automobile differential pinion shaft. Double row back-to-back internal layout enables simultaneous bearing of large radial load and bidirectional axial thrust generated during vehicle acceleration, deceleration and turning.

All bearing rings and tapered rollers adopt high-purity quenched GCr15 bearing steel, ultra-precision superfinished raceway to reduce friction heat generation during high-speed rotation of transmission system. Built-in multi-layer composite contact seals block gear oil leakage and prevent metal debris, dust from entering bearing interior. Pre-filled high-temperature gearbox extreme pressure grease inside, stable anti-fatigue performance under long-time variable speed and variable load driving conditions. Compact integrated structure saves differential internal layout space, widely matched with passenger car, light commercial vehicle drive axle differential pinion transmission assembly.
