Shaft Seal – Simering 69x85x10 BO NBR Simmering 69mm 1pc.

Type BO – shaft seal in open metal housing with additional dust lip.

NBR rubber – also known as acrylonitrile-butadiene rubber or nitrile rubber for short. One of the most popular polymer grades currently used for the production of technical seals. Excellent resistance to mineral oils and greases, very good stability at low temperatures (down to -30°C), not recommended at very high temperatures (>100°C). High resistance to oils and non-flammable hydraulic fluids, resistant to abrasion. Not resistant to ozone, brake fluids, hot water.

Simmer rings / Simerings are technical seals used for radial sealing of rotating shafts. The purpose of the Simering seal is to prevent oil or grease from leaking where the rotational motion is transmitted. Color black.
