Designed for industrial gearboxes and reducers, these radial shaft seals focus on reliable sealing stability—helping reduce leakage risk and supporting longer maintenance intervals.
Reliable lip preload through spring-energized structure
Optional dust lip to resist contamination ingress
Material options to match oil types and operating conditions
Custom sizes for hard-to-source replacements
