Rotary Shaft Seal 30x38x5 NBR AO Oil Seal Double Lip

Construction and design

The Rotary Shaft Seal 30x38x5 NBR AO Oil Seal Double Lip is a reliable sealing component designed for rotating shafts in mechanical systems operating with lubricating oils and greases. Its design allows the seal to retain lubricants inside the system while preventing external contaminants from entering the machine.

The sealing element is manufactured from NBR nitrile rubber, a material widely used in technical sealing applications because of its excellent resistance to mineral oils, lubricants and many hydraulic fluids. NBR elastomer also provides flexibility and durability, ensuring stable sealing performance over long operating periods.

The AO construction features a double lip design. The primary sealing lip retains the lubricating medium inside the system, while the secondary dust lip protects the sealing area from dirt, dust and environmental contamination.
