Pinion seals

Pinion seals
SKF pinion seals are built to meet or exceed OE specifications. The complete line of SKF pinion seals includes direct replacement designs, double lip (DL) designs and unitized designs.

The DL pinion seal, made from a proven fluoroelastomer that's been enhanced for improved sealing performance, features a patented Waveseal® bi-rotational design that dissipates heat and reduces wear. A rugged excluder lip and a radial dirt lip offer two barriers against dirt and contamination, while a Bore-Tite® sealant on the outer diameter eliminates oil leaks caused by scratches or minor imperfections in the bore.

The unitized pinion seals offer the optimum sealing performance with extended life. The superior design provides a perfectly matched running surface for the sealing lips made from highly engineered fluoroelastomer. High temperature capable with extensive exclusion properties provides long life in a highly aggressive application. The unitized design incorporates the patented wave seal that sweeps lubricant back to the bearings promoting cooler running operation. Another innovative feature of this seal adding long life is the 1/2 metal, 1/2 rubber ID allows for heat dissipation while holding a positive grip on the shaft.
