Tapered roller bearings
Tapered roller bearings are manufactured from high-quality, high-carbon chromium bearing steel and undergo precision heat treatment, resulting in high load-carrying capacity and excellent impact resistance. Their unique tapered raceway design ensures pure rolling contact between the rollers and the raceways, enabling them to effectively withstand radial loads and unidirectional axial loads. The products strictly adhere to national standard dimensions, offering smooth operation and low noise levels. They are widely used in automotive wheel hubs, gearboxes, mining machinery and machine tool spindles, providing reliable support that ensures long service life and high precision for equipment.
