AO/TC Double-Lip Design

The AO/TC design incorporates two functional sealing lips.

The spring-loaded primary sealing lip maintains sealing contact with the rotating shaft. The additional dust lip helps prevent dust, dirt and other external contaminants from reaching the primary sealing area.

NBR Nitrile Rubber

The seal is manufactured from NBR nitrile rubber, a material widely used for radial shaft seals operating with mineral oils and greases.

Actual compatibility should be verified against the specific lubricant, temperature and operating conditions.

Correct Selection of 105x125x12 Oil Seal

For precise identification, verify the complete specification:

GRN® -> 105x125x12 mm -> NBR -> AO/TC -> Double Lip

Matching dimensions alone do not guarantee full interchangeability. The material and sealing lip configuration should also correspond to the requirements of the application.
