Round Cap Cover
Round flanged covers can be used to cover protruding shafts and gears. Significant extra height can be gained by manufacturing the covers in a stacked manner. Round flanged covers are also called bearing caps or shaft caps
Round flanged 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.
Available in 3/16″ heavyweight plastic and 1/8″ lightweight plastic. The lightweight material is intended for less abusive environments.
Note: Part of the flange can be trimmed if there are interference issues.
