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

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.
