Self-aligning Ball Bearings
Self-aligning Ball Bearings mainly
bear radial load, axial load and can be subjected to a smaller. Shaft
(shell) of the axial displacement constraints in the clearance limits,
has self-aligning capability, to allow the inner periphery relative
tilt, not under normal working conditions, suitable for bearing seat
hole can strictly ensure the coaxiality of part. Suitable for precision
instruments, low noise motor, automobile, motorcycles, metallurgical,
mining, petroleum, rolling mill, paper, cement, sugar and other
industries and general machinery etc..
