Description
19000332633331311 main gear bearing is a heavy-duty rolling bearing specially designed for the center axle gearbox of Sinotruk Howo heavy trucks. It is installed on the main gear shaft of the middle axle gearbox, supporting the rotation of the main drive gear and bearing huge radial load and axial load generated during power transmission. Adopting high-quality bearing steel and precision grinding process, together with professional heat treatment, the bearing features high hardness, good fatigue resistance and strong impact resistance. It can adapt to severe working conditions such as heavy load climbing, frequent starting, bumpy mountain roads and long-distance continuous transportation. It keeps the main gear rotating smoothly, ensures accurate gear meshing, reduces friction loss, and protects the gear and shaft from early wear. Each bearing undergoes strict dimensional inspection, rotational flexibility test, noise detection and fatigue test before delivery, effectively avoiding common problems such as bearing heating, noise, pitting and sticking. It is a necessary replacement part during middle axle gearbox overhaul. We maintain sufficient inventory and stable bulk supply for repair workshops, fleet operators, auto spare parts dealers and global cross-border export customers.
