Set screw ball bearings

For over 70 years, Dodge® has been talking to mounted bearing users and listening to their needs. This experience lead to the design of the optimum mounted ball bearing. A state-of-the-art facility was built to manufacture the new Dodge design. The result is the Dodge SC/SCM line. Its premium features make it the most reliable set screw mounted ball bearing on the market and provides the user unmatched quality and true total value.

Superior locking force
Dodge uses 65º spacing for set screws. This unique design offers an optimum balance between locking force and inner ring stress.

Housing designed for snap-on end cover
SC/SCM bearings contain a machined groove in the housing to accommodate a snap-on style polymer end cover. The end cover provides additional protection from the environment and creates a safer working environment for employees maintaining equipment. Covers are OSHA yellow.

The snap-on style end cover incorporates an additional lip on the mounting surface for a more rigid fit within the housing and enhanced sealing. The design is more durable than a bolt-on style that uses the grease fitting to secure the cover in place and can be easily knocked off the bearing housings. Closed and open end covers are available.

Stronger, more flexible cage
The SC/SCM uses a ball cage that is made of heat stabilized nylon with fiber-glass reinforcement for added strength. The nylon material provides a natural lubricity for longer life. Fiberglass reinforcement allows higher operating temperatures than plain nylon, is more resistant to fatigue than metallic cages, and prevents the cage from retaining moisture in wet environments. Short fiberglass allows greater flexibility than steel or normal fiberglass, especially under misalignment. That means longer life in applications where some degree of misalignment is unavoidable.

Patented DualGuard seal
Dodge SC/SCM products use the patented DualGuard sealing system that offers maximum protection in tough environments. The DualGuard seal consists of two patented features that are unique to Dodge bearings.
• Land-riding single lip seal
   - Made of nitrile rubber
   - Provides positive contact with the inner ring
   - Assures uniform lip contact to keep contaminants out and seal in lubricant
   - Mechanically retained seal adds strength and allows grease to purge

• Rubberized flinger
   - Industry’s first and only patented design
   - Molded rubber provides additional protection against contaminants entering the bearing
   - Baffle design of the rubber on the external surface of the flinger enhances the removal of liquid during rotation
   - Rubber baffles create a turbulent airflow around the seal to help protect against airborne contaminants
   - Grease chambers on the internal surface prevent lubricants from exiting the bearing
