Industrial gearboxes need consistent sealing to protect lubrication and minimize downtime. This durability-focused radial shaft seal supports stable fit and long service life with configurable lip and material options.
Stable lip preload with spring energizer
Optional dust lip for contamination defense
Material options to match temperature and lubricant requirements
Custom sizes for replacements and OEM builds
