  • Tapered roller bearing
    Patent number: 10968947
    Abstract: A tapered roller bearing includes an inner ring having a large flange surface, and tapered rollers having roller large end surfaces. The large flange surface has an arithmetic mean roughness Ra of 0.1 ?m?Ra?0.2 ?m. The large flange surface further has a roughness curve skewness Rsk of ?1.0?Rsk??0.3, and a roughness curve kurtosis Rku of 3.0?Rsk?5.0. The tapered roller bearing is capable of realizing both stable rotation torque while the bearing is rotating at a low speed, and excellent resistance.
