Self-aligning Ball Bearings Simple Introduction

Self-aligning ball bearings are two raceways of inner ring and between the spherical outer ring raceway, equipped with spherical ball bearings.

The center of curvature of the Raceway surface and bearing the same with self-aligning ball bearing as self-aligning capability. When there are Flex shaft, housing can be automatically adjusted, no increase in bearing the burden. Spherical roller bearings can accommodate radial loads and axial loads in two directions. Large radial load capacity, suitable for heavy loads, shock loads. The inner diameter is tapered bore bearings, can be directly installed. Or using an adapter sleeve, demolition on barrel mounted on a cylindrical shaft. Cage used steel cages, cages of polyamide and copper alloy cages.

Self-aligning ball bearings with a cylindrical bore and tapered bore structure, cages are made of steel sheet, synthetic resins, etc. Its characteristics are spherical-shaped Raceway, Auto-Tune, to compensate for misalignment made self-aligning ball bearings and shaft deflections of errors, but the inner and outer rings relative degree of inclination must not exceed 3.

Can withstand greater radial load, and can bear axial loads. This kind of bearing Raceway is sphere-shaped, it has a self aligning performance, when axial stress in curved or tilted to make the center line and outer centre line relative slope does not exceed 1 ° ~2.5 when bearings are still able to work.

Self-aligning ball bearing bore with both cylindrical and conical. Conical bore taper for 1:1 or 1:30. In order to strengthen bearing lubrication in processing on the outer ring of the bearing oil Groove and three oil holes.
