Product Description
A tapered roller bearing is a separable rolling bearing, with its core structure consisting of four major components: the inner ring (tapered inner ring), the outer ring (tapered outer ring), the tapered rollers, and the cage. The extension lines of the raceway and the conical surface of the rollers converge at the same point on the bearing's axis of rotation, enabling pure rolling motion. This design significantly reduces friction and wear during operation, effectively extending the bearing's service life and enhancing operational stability.
Leveraging its unique structural advantages, this type of bearing can simultaneously withstand substantial radial loads and unidirectional axial loads. The larger the contact angle, the stronger its ability to withstand axial loads. Therefore, it is widely suitable for various scenarios involving heavy loads, high speeds, and complex working conditions.
Bearings are made of high-purity bearing steel (such as GCr15, GCr15SiMn) through precision quenching and grinding processes. Some high-end models adopt carburizing treatment or special alloy materials, which exhibit excellent wear resistance, corrosion resistance, and impact resistance.
