The Brief Description of Pillow Block Insert Ball Bearing :
Pillow block bearing unit is combination of an insert bearing, seal and a housing.The
internal structure of the insert ball bearing is the same with that
of deep groove ball bearing. But the inner race of this bearing is
wider than the outer race. The outer race has the spherical
surface. Insert ball bearings can self aligning with the fit
between the outer race and the bearing block. Insert ball bearings
are compact. It’s easy for loading and unloading.Pillow block bearings are widely used in mining, machinery,
automotive, textile and chenmical industries.
