WG99003329213 1st Shaft Bearing

WG99003329213 is a cylindrical roller bearing specially used for the input shaft of heavy-duty truck HW series transmissions. It supports the input shaft, bears radial loads and ensures the concentric rotation of the shaft.

It features dense material and fine processing. Its dimensional tolerance and geometric accuracy fully meet the original factory assembly requirements.

Compatible with mainstream heavy-duty truck models such as Howo and Sitrak, it can directly replace original parts without modification or adjustment.

Adaptable to complex road conditions including long-distance freight and construction site heavy-load operation, it has a compact structure and high reliability, serving as a core high-quality component for transmission repair and maintenance.

WG99003329213 main shaft bearing is forged from high-carbon chromium bearing steel and treated by quenching and tempering. It features high hardness, excellent wear resistance and outstanding radial load-bearing capacity.

Combined with precision rollers and a high-strength cage, it maintains uniform operating clearance and low friction resistance, delivering smooth transmission, low temperature rise and low noise.

Manufactured to OE standard dimensions with qualified precision and good interchangeability, it allows easy installation.

With great impact resistance, fatigue resistance and corrosion resistance, it adapts to the high-load operating conditions of the main shaft in heavy-duty truck transmissions, effectively reducing wear and failure and extending the service life of the transmission.
