Self-Alighing Ball Bearing

Self-Aligning ball bearing is between the inner ring of two raceways and the outer ring of the raceway with spherical ball bearing. There are two kinds of structures: cylindrical hole and conical hole. The material of the retaining frame is steel plate and synthetic resin.Its characteristic is that the outer ring raceway is spherical and has automatic centering ability, which can compensate the error caused by dissimilarity and axial deflection, but the relative inclination of the inner and outer ring should not exceed 3 degrees.

Application

Precision instrument, low noise motor, automobile, motorcycle, metallurgy, rolling mill, mining, petroleum, papermaking, cement, sugar press and other industries and general machinery
