For industrial equipment where downtime is costly, long-lasting radial shaft seals help keep lubricant in and contaminants out—supporting extended service intervals when selected and installed correctly.
Compound options designed for improved wear resistance
Optional dust lip to reduce abrasive ingress
Stable lip preload via spring energizer
Custom sizing for OEM builds and replacements
