7.625 X 8.875 X 0.500" SKF/CR Oil Seal

Radial shaft seals are used between rotating and stationary machine components, or between components in relative motion. HDW1 seals are designed with a sealant coated double metal case. They have an SKF WAVE lip made of nitrile rubber with a higher pumping rate to reduce heat generation. The seal also has a garter spring to optimize sealing against the shaft.

• For oil or grease
• With garter spring
• WAVE lip creates higher pumping rate
• WAVE lip has less friction between shaft and lip
• WAVE lip has a lower temperature at the contact point
