SKF Radial Shaft Seal, 55mm Inside Diameter, 80mm Outside Diameter - 55X80X8 HMS5 RG

This radial shaft seal is a rotary sealing component designed to prevent fluid leakage and exclude contaminants around rotating shafts in mechanical assemblies. It is intended for use where a resilient sealing lip is required to maintain separation between lubricated and non‑lubricated spaces in rotating equipment.

Features and Benefits:

• Nitrile rubber construction resists oil‑based media exposure
• Single‑piece lip design maintains dynamic sealing contact
• Withstands elevated temperatures typical of NBR performance
• Robust tear resistance improves service life under shaft movement
• Compatible with standard shaft housings for straightforward replacement

Applications

• Suitable for automotive driveline and gearbox sealing duties
• Used with rotating pump shafts in oil‑handling systems
• Ideal for industrial gearbox retrofit and repair tasks
• Can be used for agricultural machinery with exposed shafts

What shaft size does this seal accept?

It fits an internal shaft diameter of 55 mm.

What external housing bore is required for installation?

The seal requires an outer bore diameter of 80 mm for proper seating.

How thick is the sealing element for axial space planning?

The component has a thickness of 8 mm for axial accommodation.

What elastomer is used for the sealing lip and why?

The lip is MADE from nitrile rubber, selected for compatibility with oil‑based fluids and mechanical wear resistance.
