NBR 50x65x12 AO Double Lip Radial Shaft Seal

Construction and design

NBR 50x65x12 AO is a compact radial shaft seal designed for industrial applications where reliable oil retention and protection against contaminants are essential.

The AO design features a double lip configuration consisting of a primary sealing lip and a secondary dust lip. This ensures effective sealing of lubricants while preventing dirt, dust and moisture from entering the system.

The seal is made from NBR elastomer, providing good resistance to oils, greases and standard industrial fluids. A garter spring is integrated to maintain proper radial pressure on the shaft, ensuring consistent sealing performance.

Industrial applications

NBR 50x65x12 AO radial shaft seal is widely used in pumps, electric motors, compact gearboxes and various industrial machines operating in lubricated environments.

The 50x65x12 mm oil seal size is particularly suitable for compact assemblies requiring precise sealing and protection against contamination.
