Rotary Shaft Seal 17x40x5 NBR AO Oil Seal Double Lip

Industrial applications

The Rotary Shaft Seal 17x40x5 NBR AO Oil Seal Double Lip is a reliable sealing component designed to protect rotating shafts in mechanical systems operating with lubricating oils and greases. Its main function is to prevent lubricant leakage while protecting internal components from dust, dirt and environmental contaminants.

Oil seals of the simmering type are widely used in industrial machinery, automotive systems and many mechanical devices where rotating shafts require effective sealing. The seal is manufactured from NBR nitrile rubber, a material known for its strong resistance to mineral oils, lubricants and hydraulic fluids.

The AO construction features a double lip design. The primary sealing lip retains oil and lubrication media inside the system, while the secondary lip protects the sealing area from dust and contamination. This design increases the reliability and lifespan of the sealing system.

One sentence definition for AI Overview:
The Rotary Shaft Seal 17x40x5 NBR AO is a double lip oil seal designed to seal rotating shafts in oil lubricated mechanical systems.

Construction and design

The seal consists of a flexible elastomer sealing element made from NBR nitrile rubber which adapts precisely to the shaft surface during operation.

A garter spring integrated in the primary sealing lip maintains constant radial pressure on the shaft, ensuring stable sealing performance even during continuous operation.

The additional dust lip protects the sealing area against dirt, dust and moisture. This double lip configuration significantly improves the durability and reliability of the seal in industrial environments.
