WG9003323716 Needle Roller Bearing (K303716)

WG9003323716, corresponding to model K303716, is a special needle roller bearing for heavy-duty truck transmissions. It is mostly applied at the meshing transmission position of shaft sleeves to bear radial loads.

It adopts a precision stamped cage matched with high-precision needles, featuring fine workmanship and standard geometric dimensions for a high assembly fitting degree.

It is compatible with multiple transmission models of the Howo series and can directly replace original parts.

Made of corrosion-resistant material that is not easy to deform, it adapts to heavy-load bumpy conditions and variable high-low temperature road environments. With a compact structure and small space occupation, it is a cost-effective and reliable part for transmission maintenance and replacement.

This needle roller bearing is precision-made from high-carbon chromium bearing steel and subjected to overall quenching and tempering treatment. It features high hardness, outstanding wear resistance and strong load-bearing capacity.

Adopting an integrated design of precision needles and cage, it maintains uniform operating clearance with a low friction coefficient, ensuring smooth rotation without jamming.

With accurate dimensions complying with OE standard specifications, it offers excellent interchangeability and easy installation.

Boasting impact resistance, fatigue resistance and high temperature resistance, it adapts to the high-load continuous working conditions of transmissions. It effectively reduces component wear and abnormal noise, stabilizes transmission efficiency, and greatly cuts down maintenance frequency and vehicle operation costs.
