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
Open (No Seal)
No seals or shields. Allows external lubrication and cooling. Lowest friction, highest speed capability.
Best forClean environments with external lubrication systems. High-speed applications where heat dissipation matters.
Avoid forDirty, dusty, or wet environments. Applications without planned lubrication maintenance.
Examples
- Machine tool spindles
- Gearboxes with oil bath lubrication
- High-speed precision equipment
