Premium general purpose springless grease seal with integrated metal reinforcement element for press-in fitment in an open housing. Designed to control leakage in grease-packed bearings.
The springless lip imparts low friction and heat generation. The rubber-covered outer diameter creates excellent static sealing without excessive damage to soft alloys. This is an excellent low friction seal for non-pressurized media such as grease or highly viscous fluids.
Size Table (Inch)Standard 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.
