Oil seal 70x130x10/17 MSS7 NBR

The MSS7 70×130×10/17 NBR rotary shaft seal by FST is a modular cassette-type radial shaft seal designed for demanding rotating applications. The integrated design combines a spring-loaded sealing lip with additional dust lips, supporting operation in contaminated and industrial environments.

The seal body is made of NBR elastomer and supplied as a complete modular unit, allowing easier installation and tolerance compensation in the housing bore. Factory-applied grease supports proper sealing during initial operation.
