End covers are available in both open-ended and closed-ended styles and are designed to fit both standard and customized Timken spherical roller bearing block units
All auxiliary covers bolt directly onto the bearing block units
This bolt-on cover is made from durable urethane rubber, however steel covers are also available. The steel versions are black-oxide treated for added corrosion resistance in most instances. Nickel plating is available on certain select sizes
The CJ covers are for Timken QM bearing block units that employ eccentric shaft collars
The open-ended urethane covers can be ordered with either a DR nitrile triple lip or VR V-ring nitrile seal
The low speed triple lip DR seal can move within the cover opening to accommodate misalignment while maintaining full contact to the shaft for positive sealing. This seal type is default on HSY backing plates
The high speed V-ring VR seal rides on two surfaces. It seals both axially and radially. This seal type is default on UFP backing plates
Every cover is outfitted with a grease fitting to fill the cover cavity with grease for an added barrier against contamination
