1.Double row self-aligning bearings utilize an inner ring with two rows of balls in two deep raceways, and an outer ring with a single spherical raceway. In this way, the inner and outer rings can be misaligned relative to each other. The resulting effect is a comparatively large angle imposing moment loads upon the balls.
2.The self-aligning ball bearing has two rows of balls. The raceway of the outer ring has the form of a hollow sphere. The inner ring, the cage and the balls are designed so that they can be pivoted by a few angular degrees from the central position. Misalignments as well as sags of the shaft can thus be equalized by the self-aligning ball bearing. The load can either be carried out axially or radially in both directions.
2.This 1311 self aligning bearing is a high-quality and premium bearing that is manufactured to strict quality control standards. It features a 55 straight bore and will be supplied with the standard C3 internal clearance and W33 Lube Groove unless otherwise requested.
2.Self-aligning Ball Bearing Application:
Aligning ball bearings is used to withstand heavy load and impact load,
low noise motors,
sugar and other industries,
3.Self-aligning Ball Bearing Features:
Self-aligning bearing for applications subject to shaft deflections or misalignments between the shaft and housing Straight bore for fitting on a conventional cylindrical shaft Steel cage evenly spaces balls for reduced friction, vibration and noise Open bearing for lubrication applied in place CN (normal) radial internal clearance for applications that do not involve thermal expansion or atypical precision
