WG9003395320 (Model K455320) needle roller bearing is exquisitely manufactured from premium high-carbon chromium bearing steel. Treated by quenching, tempering and precision finishing, it delivers high hardness, exceptional wear resistance, as well as outstanding impact and fatigue resistance.
It features a compact structure with great radial load capacity, perfectly suited for the narrow mounting space inside gearboxes. The evenly arranged and high-precision needle rollers ensure smooth operation with low friction, achieving quiet transmission without jamming.
Made to original factory standard dimensions, it offers excellent interchangeability for direct vehicle installation and replacement. Compatible with full-range supporting gearboxes of Sinotruk, it withstands high-frequency and heavy-duty working conditions, resists looseness and eccentric wear, and enjoys an extra-long service life, making it an optimal choice for maintenance and replacement.
