0735 301 599 Small Rear Thrust Bearing of Main Shaft

0735 301 599 Small Rear Main Shaft Thrust Bearing is a critical limiting and load-bearing component inside the ZF 12TX series 12-speed automatic transmission. It is mounted at the rear end of the main shaft and undertakes the functions of axial buffering and positioning support.

Adopting precision stamping, gear grinding and polishing processes, it features high flatness and uniform stress distribution, fully complying with the original assembly precision of the gearbox.

It adapts to complex working conditions such as long-distance trunk transportation, mountain heavy-load driving and frequent start-stop operation. It effectively eliminates axial play, operating abnormal noise and abnormal component wear. With original universal specifications, it is easy to disassemble and install, making it an essential original part for gearbox maintenance and replacement.

This small rear thrust bearing for the main shaft is an original supporting part for ZF 12-speed AMT gearbox. It is precisely forged from high-carbon chromium bearing steel and integrally quenched and tempered, featuring high hardness, outstanding wear resistance and compression resistance.

The contact surface is precision lapped with low frictional resistance, which can accurately bear the axial thrust at the rear of the main shaft and achieve stable limiting without axial displacement.

It performs well in high and low temperature resistance and anti-fatigue deformation, and is not prone to seizing or eccentric wear under frequent gear shifting and heavy-load working conditions.

With original factory standard dimensions that perfectly fit the assembly clearance, it can be directly installed in place. It effectively reduces gearbox abnormal noise, protects the shaft and gears, and extends the service life of the assembly.
