AO/TC Double-Lip Design

The AO/TC design combines two functional sealing lips.

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

NBR Oil Seal

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 checked against the specific lubricant, temperature and operating conditions.

115x140x12 A vs AO/TC

The complete designation is important when selecting this seal:

GRN® -> 115x140x12 mm -> NBR -> AO/TC -> Double Lip

A 115x140x12 A NBR seal should not automatically be treated as equivalent. The A version is a single-lip design, while AO/TC has an additional dust lip.
