1.Abstract:Self-aligning ball bearings are constructed with the inner ring and ball assembly contained within an outer ring that has a spherical raceway. This construction allows the bearing to tolerate a small angular misalignment resulting from deflection or improper mounting. A self-aligning bearing has an elastic plastic outer layer for engaging a bearing seat, so that it can be tilted. In order to ensure the alignment in a large range, elastically bendable substantially radially directed projections are formed on the plastic outer surface, and are supported on the radial surface of the bearing seat. 2.Specifications:1).strong technology service support 2).low noise and long working 3).competitive price 3.applications:Home appliances, low noise and high speed electric motors, automotive components, pumps, machinery
