1. Self-Aligning Ball Bearing
The self-aligning ball bearing is a bearing in which an inner ring of two raceways and an outer ring of a spherical race are fitted with spherical balls. The self-aligning ball bearing has two structures of a cylindrical hole and a tapered hole, and the material of the cage is steel plate, synthetic resin and the like. The characteristic is that the outer ring raceway has a spherical shape and has self-aligning property, which can compensate for the error caused by different heart degrees and shaft deflections, but the relative inclination of the inner and outer rings must not exceed 3 degrees. Self-aligning ball bearing type code is 1 (1200/1300/2200/2300).
