0735 301 274 Main Shaft Thrust Bearing

0735 301 274 Main Shaft Thrust Bearing is a key axial load-bearing component for ZF 12TX series 12-speed AMT gearbox. It is mainly used for axial limiting, buffering and pressure reduction of the main shaft.

Adopting precision integral forming technology, it features high flatness and uniform stress bearing to avoid eccentric wear.

It delivers excellent high and low temperature resistance as well as impact resistance, adapting to complex operating conditions such as long-distance logistics and engineering dump trucks.

It precisely matches the assembly clearance of the original factory assembly, effectively preventing axial play, transmission abnormal noise and premature component wear. It is an original supporting core part for the maintenance and replacement of ZF 12-speed automatic gearboxes.

Original ZF main shaft thrust bearing is made of high-precision alloy steel and integrally quenched and hardened, featuring strong pressure resistance, excellent wear resistance and high temperature resistance.

Its flat contact surface is precision ground with a low friction coefficient, which can effectively bear axial thrust and buffer the axial clearance during gearbox operation.

It runs smoothly and quietly, with great fatigue resistance and is not easy to deform or seize. It is perfectly suitable for long-term heavy-load operation and frequent gear shifting conditions.

Made to original factory standard dimensions, it fits the mounting position precisely with no need for adjustment during installation and delivers excellent compatibility. It reduces gearbox housing abnormal noise and component wear, greatly improving the operating stability and service life of the gearbox.
