AO/TC Double-Lip Design

The AO/TC design combines two functional sealing lips.

Spring-loaded primary sealing lip - maintains sealing contact with the rotating shaft and provides the main sealing function.

Additional dust lip - helps prevent dust, dirt and other external contaminants from reaching the primary sealing area.

NBR Nitrile Rubber

NBR is widely used for radial shaft oil seals operating with mineral oils and greases.

Compatibility should always be verified for the specific operating medium, temperature and working conditions.

How to Select a 28x52x10 Oil Seal

For correct identification, verify the complete specification:

28x52x10 mm + NBR + AO/TC + GRN®

Matching dimensions alone do not guarantee full interchangeability. The elastomer material and sealing lip design must also correspond to the application requirements.
