3-Bolt Bearing Covers
3-Bolt bearing covers or bearing caps are for covering 3-bolt flanged bearings.
Bearing covers protect bearings from environmental hazards.
3-Bolt bearing covers are usually fastened to the structure the bearing is attached to by the flange, drilling two holes in the flange and the underlying structure. It is advised to use self-tapping screws or nuts and bolts. For further installation instructions, see our flanged bearing cover installation guide.
Available in our standard 3/16″ heavyweight plastic and 1/8″ lightweight plastic.
