Rotary Shaft Seal 11x17x4 NBR SC Single Lip Oil Seal

Main Description

The Rotary Shaft Seal 11x17x4 NBR SC Single Lip Oil Seal is a compact sealing component designed for effective sealing of rotating shafts in industrial, automotive, and mechanical applications. Manufactured from durable NBR nitrile rubber, this oil seal provides reliable protection against oil leakage, grease loss, and contamination in systems operating under standard industrial conditions.

The SC construction features a flexible sealing lip combined with an additional outer dust protection profile, improving sealing stability and helping protect the internal mechanism from dirt and moisture. Thanks to its compact dimensions, the 11x17x4 mm oil seal is commonly used in electric motors, pumps, small gearboxes, agricultural equipment, and precision drive systems.

NBR material offers good resistance to mineral oils, lubricants, and standard industrial media. The flexible sealing lip maintains consistent contact with the rotating shaft surface, reducing leakage risk and extending operational service life.

The 11x17x4 mm size belongs to the category of compact rotary shaft seals used in lightweight mechanical systems and technical devices requiring reliable sealing performance and low operating friction.
