Self Aligning Bearing 1200 Series,1300 Series
Introduction
The Self Aligning Bearing is a bearing equipped with a spherical ball between the inner ring of the two raceways and the outer ring of the spherical raceway. The center of curvature of the outer raceway surface is identical to the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the shaft and outer casing are deflected, they can be adjusted automatically without increasing the bearing load. Spherical roller bearings can withstand radial loads and axial loads in both directions. The radial load capacity is large, and it is suitable for heavy load and impact load. The inner ring inner diameter is a tapered bore bearing that can be mounted directly. Or use the adapter sleeve and the removal cylinder to mount on the cylindrical shaft. The cage uses a steel stamping cage, a polyamide forming cage and a copper alloy cage.
