0730300591 Rear Bearing Circlip of Main Shaft

0730300591 Rear Main Shaft Bearing Circlip is a key locking component of ZF 12TX series 12-speed AMT gearboxes. It is clipped into the groove of the rear main shaft bearing, serving the core functions of axial fixing, anti-disengagement and positioning limiting.

It is integrally precision formed with uniform elasticity and accurate bayonet size. Boasting high tensile strength, it is impact-resistant and not prone to notch breakage or failure.

It adapts to the high-temperature oil-immersed environment inside the gearbox, featuring rust and corrosion resistance, and maintains stable locking force during long-term high-load operation.

With original standard dimensions and good interchangeability, it is easy to disassemble and install. It is an essential original wearing part for gearbox overhaul and assembly, as well as for preventing bearing displacement and damage.

Original ZF rear main shaft bearing circlip is quenched and formed from high-strength spring steel. It features sufficient toughness and constant elastic force, resisting fatigue deformation, loosening and fracture.

With standard precision dimensions, it fits tightly into the groove with reliable locking and limiting performance, firmly securing the rear main shaft bearing to prevent axial play, displacement and falling off during operation.

It is oil-resistant and resistant to high and low temperatures, suitable for harsh working conditions such as heavy-load climbing and frequent gear shifting, and remains free from loosening after long-term service.

Original standard size allows direct snap-fit installation with easy assembly. It effectively avoids bearing looseness, gearbox abnormal noise and transmission faults, delivering excellent cost performance for maintenance and replacement.
