Ball Bearing Units

The NSK Bearing Unit is a combination of a Radial ball bearing, Seal, and a Housing of high-grade cast iron or pressed steel, which comes in various shapes.

The outer surface of the bearing and the internal surface of the Housing are spherical, so that the unit is self-aligning.
A duplex seal consisting of a combination of an oil-proof synthetic rubber seal and a slinger is provided on both sides.
