The outer raceway surface of the self-aligning roller bearing is spherical, and the shape of the inner raceway surface is consistent with the two rows of self-aligning roller busbars. The center of the raceway surface of the outer ring is consistent with the center of the bearing, and has the aligning performance to adapt to the application of the shaft tilt. Even if there is installation error with the bearing seat or shaft deflection caused by the inner and outer ring tilt occasions can also operate normally. Bearing can bear large radial load, two-way axial load and their combined load, suitable for bearing vibration, impact load applications. However, in the use of excessive axial load, the roller load of the roller row that does not bear the axial load becomes smaller, and the roller is easy to slide, resulting in poor lubrication. When the ratio of axial load to radial load exceeds the constant E(FA/FR S2E) in the size table, please consult us. In addition to bearings with cylindrical bore bore, bearings with tapered bore bore are also available. Tapered bore bearings are represented by "K" after the basic code, and the standard taper is 1/12, but the taper of 240 and 241 bearing series is 1/30, and is represented by "K30" after the basic code. Tapered bore bearings are almost all fixed to the shaft with tight bushing or disconnecting bushing.
