SKF Radial Shaft Seal, 72mm Inside Diameter, 100mm Outside Diameter - 72X100X10 HMSA10 RG

This radial shaft seal is designed to prevent fluid leakage and exclude contaminants in rotary shaft assemblies within industrial equipment. Constructed from nitrile rubber, it provides a resilient sealing lip for dynamic applications where shaft rotation requires a tight Interface between moving and stationary components.

Features and Benefits:

• Nitrile rubber material offers resistance to oils and greases
• Rotary configuration maintains continuous contact during rotation
• Robust sealing lip reduces ingress of dust and dirt
• Durable construction supports repeated shaft movement

Applications

• Suitable for oil‑sealed gearbox shafts
• Used with motor drive shafts in industrial machinery
• Ideal for pump shafts handling lubricated environments
• Can be used for rotating couplings requiring fluid retention

What internal dimension is the seal designed to fit?

It fits shafts with a 72 mm inside diameter.

What external dimension should the housing accept for correct installation?

The housing bore must accommodate a 100 mm outside diameter.

How thick is the sealing element for axial accommodation?

The seal has a 10 mm thickness.

What compound is the lip MADE from and why is it chosen?

The lip is formed from nitrile rubber to provide compatibility with oils and common lubricants.
