Description

SUNBEARING Cylindrical roller bearing is of high load capacity and can operate at high speeds because they use rollers as their rolling elements. This kind of bearing is generally only used to bear radial load, compared with the same size deep groove ball bearings, have a greater radial load capacity, speed close to the deep groove ball bearings, but with such a bearing with the shaft higher processing requirements shell holes, allowing the inner ring and outer ring axis tilt axis is small as beyond the limits of the two-axis tilted roller in contact with the ring raceway situation will deteriorate severely impact of load-bearing capacity, reduce bearing life. Therefore, these bearings need to be installed, such as the role of the host axial load component, only the simultaneous use of other types of bearings to withstand the axial load premise before use.
