Internal Clearance
Normal Clearance (CN)
Standard radial internal clearance. Suitable for most applications under normal operating conditions.
Best forGeneral-purpose use. Normal temperatures, standard fits, moderate speeds.
TemperatureUp to ~70°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
