AO/TC Double-Lip Design

The AO/TC design features:

Spring-loaded primary sealing lip - provides dynamic sealing contact with the rotating shaft.

Additional dust lip - helps limit the ingress of dust, dirt and other external contaminants into the primary sealing area.

This additional dust lip distinguishes the design from a corresponding single-lip radial shaft seal.

NBR Nitrile Rubber

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

Material compatibility should always be verified against the specific operating medium and conditions.

How to Select a 32x52x7 Oil Seal

For correct identification, verify the complete specification:

32x52x7 mm + NBR + AO/TC

Dimensions alone do not establish full interchangeability. The elastomer material and sealing lip design must also match the application requirements.
