The RunFine 4 Bolt Flange Bearing Units NAF300 serie 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.



The inside construction of the ball bearing for the unit is such that steel balls and retainers of the same type as in series 62 and 63 of the Deep Groove Ball Bearing are used. A duplex seal consisting of a combination of an oil-proof synthetic rubber seal and a slinger is provided on both sides.
