This high-performance seal design incorporates a formed primary seal lip and an opposed secondary lip that provide dirt exclusion and act as a lube retainer, typically used for gearboxes and environmental seals. It may be used either lubricated or unlubricated. It is designed specifically for high-speed and low pressure sealing applications.
Size Table (Inch)Standard Range sizes listed below are preferred sizes for new design applications; however, we offer any other seal size as required.Seals are available for any shaft diameter size in 0.001 inch increments, including Functional Range.
