1. Features
High load capacity: The structure of tapered roller bearings enables them to withstand combined radial and axial loads. They can accommodate the diverse complex loads experienced by wheels during operation, including the vehicle's own weight and impact loads caused by uneven road surfaces.
Low friction and high efficiency: Optimised roller end design and flange surface finish promote the formation of a hydrodynamic lubrication film, thereby reducing friction. This not only minimises friction heat generation and flange wear but also enables the bearing to better maintain preload, operate at lower noise levels, and enhance both efficiency and service life.
Quiet rotation: The rollers are manufactured to extremely precise tolerances and dimensional accuracy, achieving near-perfect uniformity. This ensures optimal load distribution, minimising noise and vibration. Concurrently, the convex raceway profile optimises load distribution along the contact surface, reducing stress peaks at the roller ends and further lowering operational noise to meet quiet rotation requirements.
Ease of installation and maintenance: The inner ring, outer ring, and rolling element assembly of tapered roller bearings are separable. This separability facilitates installation, disassembly, and maintenance. When servicing wheel bearings, the inner ring, outer ring, and rolling elements can be easily separated for inspection and replacement, enhancing maintenance efficiency and reducing servicing costs.
