Sell INA bearing distributor -self-aligning ball bearing

Description

Self-aligning ball bearing is recommended when alignment of the shaft and housing is difficult and the shaft may flex. The outer ring has a spherical raceway and its center of curvature coincides with that of the bearing; therefore, the axis of the inner ring, balls and cage can deflect to some extent around the bearing center. Pressed steel cages are usually used. Since the contact angle is small, the axial load capacity is low. The permissible dynamic misalignment is approximately 0.*7 to 0.*2 radian (4 to 7 degrees) under normal loads.

This type of bearing has two columns of ball bearing outer ring, have a common concave spherical groove type.So bearing is self-aligning, from shaft bearing the relative to the box in the wrong influence. It is especially applicable to those who may generate a large axis of the bearing or are not bending applications. In addition, self-aligning ball bearings in all the rolling bearing, friction in the lowest it even in high speed can also keep low temperature.
