Self-aligining 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..
