AO/TC Double-Lip Design

The primary sealing lip operates against the rotating shaft and is supported by a garter spring to maintain sealing contact.

The additional dust lip provides a secondary barrier against dust, dirt and other external contaminants, helping protect the primary sealing area.

NBR Nitrile Rubber

The seal is manufactured from NBR - Nitrile Butadiene Rubber, a material widely used for radial shaft seals operating with compatible mineral oils and greases.

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

Correct Selection of 50x65x8 Oil Seal

Complete product identification:

GRN® -> 50x65x8 mm -> NBR -> AO/TC -> Double Lip

When selecting a replacement, verify all three dimensions together with the material and sealing lip configuration. Matching 50x65x8 mm dimensions alone does not guarantee full interchangeability.
