Rotary Shaft Seal 25x35x7 B1 NBR - Oil Seal

Rotary Shaft Seal 25x35x7 B1 NBR - One-Lip Oil Seal with Metal Outer Surface

The Rotary Shaft Seal 25x35x7 B1 NBR SC is a high-performance one-lip oil seal designed to provide reliable radial sealing of rotating shafts. Manufactured from NBR (nitrile butadiene rubber), this seal offers excellent resistance to oils, greases, and light chemicals, making it ideal for use in demanding industrial and automotive environments.

This seal features a metal outer surface (type SC/B1) that ensures a tight fit in the housing, especially where high forces push the seal out of the bore. It withstands working pressures of up to 0.05 MPa, making it a solid choice for a wide range of machinery and equipment.

Designed in accordance with DIN 3760 / ISO 6194, the 25x35x7 B1 NBR shaft seal can be mounted in standard open grooves. The integrated spring-loaded sealing lip guarantees long-term performance and secure operation even under continuous use.
