UCP 316 Plummer Block Bearings

 

        Our product is 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.

 

        Depending on the type, the following methods of fitting to the shaft are employed: 

 

(1) the inner ring is fastened onto the shaft in two places by set screws. 

 

(2) the inner ring has a tapered bore and is fitted to the shaft by means of an  adapter.

 

(3) In the eccentric locking collar system the inner ring is fastened to the shaft by  means of eccentric grooves provided at the side of the inner ring and on the collar.
