AO Double-Lip Design

The AO design combines a spring-loaded primary sealing lip with an additional dust lip.

The primary lip provides dynamic sealing against the rotating shaft. The additional lip helps prevent dust, dirt and external contaminants from reaching the main sealing area.

NBR Oil Seal

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

Compatibility should be verified for the actual lubricant, temperature and operating conditions.

Correct Selection

For correct identification, verify:

125x142x13 mm + NBR + AO + GRN®

Dimensions alone do not guarantee interchangeability. Other 125x142x13 mm NBR seals with different sealing designs are available, so the lip configuration must also be considered.
