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
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.
