NBR 120x145x15 AO Double Lip Radial Shaft Seal

Construction and design

NBR 120x145x15 AO is a radial shaft seal designed for industrial applications requiring reliable oil retention and protection against external contaminants.

The AO design features a double lip configuration consisting of a primary sealing lip and an additional dust lip. This construction ensures effective sealing of lubricants while preventing the ingress of dirt, dust and moisture.

The sealing element is made of NBR elastomer, which provides good resistance to oils, greases and typical industrial operating conditions. The integrated garter spring ensures consistent contact pressure on the shaft for stable sealing performance.

Industrial applications

NBR 120x145x15 AO radial shaft seal is widely used in gearboxes, electric motors, pumps and industrial machinery operating in oil lubricated environments.

The 120x145x15 mm oil seal size is commonly applied in equipment requiring durable shaft sealing and protection against contamination in medium and heavy duty industrial systems.
