Small axial height bearing grease seal


Small axial height bearing grease seal

A non-metal seal designed to control leakage in grease-packed bearings.

The springless lip imparts low friction and heat generation. The elastomer outer diameter creates excellent static sealing and compensates for thermal cycling.  The small footprint of this seal allows it to be fitted in closed grooves.  This style is available in a wide range of elastomers and small quantities for repairs and seal replacement and can be shipped in 1 to 3 days.
