This original ZF 0735 301 275 idler needle bearing is compatible with 12AS series 12-speed AMT transmissions. It is precisely made of high-carbon chromium bearing steel and overall treated by quenching and hardening, featuring strong load capacity, excellent impact resistance and fatigue resistance. The needles are arranged precisely and evenly with a low friction coefficient, ensuring smooth and quiet operation and greatly reducing wear between the idler gear and idler shaft. Manufactured in strict accordance with OEM tolerance standards, it provides high fitting accuracy after installation. It is not prone to disintegration, jamming or overheating under heavy-duty conditions and enjoys a long service life, making it a core precision replacement part for the maintenance of the transmission idler assembly.
0735 301 275 Idler Needle Bearing
Part No. 0735 301 275 Idler Needle Bearing is installed between the idler gear and the idler shaft, serving the critical functions of radial load bearing and rotational friction reduction.
Designed with a precision needle roller structure, it features a compact layout and high radial load capacity, ideal for the limited installation space inside the transmission.
Made of wear‑resistant and high‑temperature resistant material, it can withstand long‑term alternating loads and impact shocks caused by frequent reverse gear shifts.
It is compatible with ZF 12‑speed AMT transmissions such as 12AS2330, 12AS2530 and 12AS2730 used in heavy‑duty trucks and buses. It effectively resolves faults including idler gear abnormal noise, looseness, sticking and excessive wear, delivering stable and reliable transmission performance after installation.
