TC Double-Lip Design

The TC design features two functional sealing lips.

The spring-loaded primary sealing lip maintains dynamic 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 in radial shaft sealing applications involving mineral oils and greases.

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

Correct Selection of 20x34x7 Oil Seal

For precise identification, verify the complete specification:

GRN® -> 20x34x7 mm -> NBR -> TC -> Double Lip

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