Sealmaster® Material Handling Mounted Ball Bearings
Sealmaster material handling mounted ball bearings feature cast iron housings and an extended inner race insert bearing with nylon retainer. The insert features a rivet to help prevent outer ring rotation and is available with setscrew or SKWEZLOC® concentric locking collar designed for commercial tolerance shafting and optional end cap. The contact seal, with black oxide treated flinger, provides a good balance between contaminant resistance, grease loss and friction. These bearings are available in common unit material handling industry bore sizes and housing configurations.
Unit Material Safety Cap for Sealmaster® Material Handling Bearings
The bearings are designed to accept either a plastic snap in or easy-to-install mechanically fastened metal safety caps. The caps are design to protect users from the exposed rotating shafts, reducing safety hazards around various types of equipment. These safety caps allow users to better conform to OSHA requirements.
