WG9003336218 (336218) is a heavy-duty rolling bearing specially designed for Sinotruk, applicable to key transmission positions of gearboxes and axles of Sinotruk Howo and other series models.

Forged from GCr15 high-carbon chromium bearing steel and treated by vacuum quenching and tempering, it features high hardness, good toughness, as well as excellent fatigue resistance and wear resistance.

The rollers and raceways are precisely ground with a large contact area and strong load-bearing capacity, capable of withstanding heavy radial loads and bidirectional axial loads simultaneously.

Adopting an optimized sealing structure, it provides effective dust and contamination prevention and avoids grease leakage. Suitable for harsh working conditions such as mines and engineering sites, it operates stably with low noise and long service life. With original factory quality and good interchangeability, it is a hassle-free option for maintenance and replacement.
