End caps are made for uses in which the shaft does not go through the housing wall of the bore. The bearings are shielded by the end cover. The covers include housing bores for rotary shaft seals built into their design. The tolerances are the same as those for a seal's O.D. Nitrile rubber serves as the exterior seal, and carbon steel serves as the interior housing.
