Internal Clearance
Greater Than Normal (C3)
Increased radial internal clearance. Required when bearings operate at elevated temperatures or with tight shaft fits.
Best forHigh-temperature applications. Tight interference fits. Electric motors with frequent starts/stops.
Temperature70-150°C operating temperature
Seal Type
Rubber Sealed (2RS)
Rubber contact seals on both sides. Superior protection from contaminants. Pre-lubricated, maintenance-free.
Best forDirty, dusty, or wet environments. Applications requiring long maintenance-free operation.
Avoid forVery high-speed applications (seal friction limits top speed). Environments exceeding 110°C.
Examples
- Agricultural machinery
- Conveyor rollers
- Automotive components
- Outdoor equipment
- Washing machines
