Hitachi bearing

Tapered roller bearing mill bearings are generally only used to withstand radial loads. Compared with deep groove ball bearings of the same size, they have large radial load capacity. The limit speed is close to deep groove ball bearings, but it is compatible with such bearings. The machining requirements of the shaft and the housing hole are high, and the inclination of the inner ring axis and the outer ring axis is small (2°-4°). The inclination of the two axes is beyond the limit, and the contact between the roller and the ferrule raceway will deteriorate. , seriously affect the load capacity of the bearing and reduce the service life of the bearing. Therefore, such bearings need to be installed in the main components that are subjected to the axial load, and can only be used if other types of bearings are used simultaneously to withstand the axial load.
