Advantages - FPM Material and B1SLRS Construction

Manufactured by CORTECO, a leading global seal supplier, this rotary oil seal is made from FPM FKM (Viton type material). Compared to standard NBR seals, FPM provides superior resistance to oils and grease, higher temperature stability, and improved chemical durability.

The B1SLRS design indicates a single lip oil seal with a metal case and integrated garter spring. The spring ensures consistent radial pressure on the shaft, maintaining optimal contact and sealing efficiency even under dynamic load conditions.

This configuration is particularly suitable for demanding industrial applications where high durability and stable sealing performance are required.
