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 errors caused by different concentricity and shaft deflection, but the relative inclination of the inner and outer rings must not exceed 3 degrees

Introduction

Self-aligning ball bearing is a bearing equipped with spherical balls between the inner ring of the two raceways and the outer ring with spherical raceways.

The center of curvature of the raceway surface of the outer ring is consistent with the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the shaft and shell are deflected, it can be adjusted automatically without increasing the burden on the bearing. Spherical roller bearings can bear radial loads and axial loads in two directions. Large radial load capacity, suitable for heavy loads and impact loads. The inner diameter of the inner ring is a bearing with a tapered hole, which can be directly installed. Or use an adapter sleeve or a dismounting cylinder to install on a cylindrical shaft. The cage uses steel stamping cage, polyamide forming cage and copper alloy car cage.

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 ability, which can compensate the error caused by different concentricity and shaft deflection, but the relative inclination of the inner and outer rings shall 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 1:1 2 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.

Bearing classification: miniature series: 10x, 12x, 13x
Universal series: 12xx, 13xx, 22xx, 23xx

Main application

Self-aligning ball bearings are suitable for bearing heavy loads and impact loads, precision instruments, low-noise motors, automobiles, motorcycles, metallurgy, rolling mills, mining, petroleum, papermaking, cement, sugar extraction and other industries and general machinery, etc.
