Self-aligning ball bearings have two structures: cylindrical hole and tapered hole, and the cage is made of steel plate, synthetic resin, etc. Its characteristic is that the raceway of the outer ring is spherical and has self-aligning properties, which can compensate the error caused by the self-aligning ball bearing caused by different concentricity and shaft deflection, but the relative inclination of the inner and outer rings must not exceed 3 degrees.

It can withstand large radial loads, but also can withstand certain axial loads. The raceway of the outer ring of this type of bearing is spherical, so it has self-aligning performance. When the shaft is bent or tilted by force so that the relative inclination between the center line of the inner ring and the center line of the outer ring does not exceed 1° to 2.5°, the bearing can still work. .

There are two types of inner bores of self-aligning ball bearings: cylindrical and conical. The taper of the conical inner hole is 1:12 or 1:30. In order to enhance the lubricating performance of the bearing, an annular oil groove and three oil holes are processed on the outer ring of the bearing.

Product Features:

It mainly bears radial load and can bear small axial load at the same time. The axial displacement of the shaft (housing) is limited within the clearance limit. It has self-aligning performance and allows normal operation under the condition of relatively small inclination of the inner and outer periphery. It is suitable for components whose bearing seat holes cannot strictly guarantee the coaxiality
