Self-aligning Ball Bearing

Self-aligning ball bearing

Bearing Introduction

The self-aligning ball bearing has two volleyball-shaped rollers, and the outer ring raceway has a spherical shape. It has the ability of self-aligning, which can compensate for the deviation of the concentricity and the error caused by the deflection of the shaft, but the inner and outer rings are relatively inclined. The degree must not exceed 3 degrees.
The inner ring of the self-aligning ball bearing has two structures of a cylindrical hole and a tapered hole, and the taper of the conical inner hole is 1:12 or 1:30. In order to enhance the lubrication performance of the bearing, an annular oil groove and three oil holes are machined on the outer ring of the bearing.
The cage generally uses a steel stamping cage and a synthetic resin cage. Sometimes a polyamide cage or a copper alloy cage is also used.
