SKF Radial Shaft Seal, 80mm Inside Diameter, 110mm Outside Diameter - 80X110X12 HMS5 RG

This radial shaft seal is designed to maintain fluid retention and exclude contaminants in rotating shaft assemblies. It operates as a rotary sealing element composed of nitrile rubber, suitable for standard industrial shaft interfaces where a resilient lip is required to control leakage and protect bearings from ingress.

Features and Benefits:

• Nitrile compound provides resistance to common oils and greases
• Rotary lip design maintains sealing contact during rotation
• Robust 12mm cross-section offers stable axial support
• Engineered for consistent radial conformity under load
• Compatible with moderate thermal exposure in service

Applications

• Suitable for rotating pump shaft assemblies
• Used with gearbox input and output shafts
• Ideal for motor and alternator sealing tasks
• Can be used for agricultural machinery drive shafts
• Appropriate for industrial rotary equipment maintenance

What shaft clearance should be allowed for installation?

Allowance depends on shaft finish and tolerance, installations typically require a close interference fit on the inner sealing surface to ensure lip engagement without excessive distortion.

How should the seal be oriented during assembly?

Fit the sealing lip facing the fluid or contamination source so the lip pressure acts against the leak direction to preserve the contact surface.

What surface condition is needed on the shaft for optimal performance?

A smooth, unscored shaft with appropriate hardness and fine finish ensures uniform lip wear and prevents Rapid degradation.

How does the material behave under elevated operating temperatures?

The nitrile formulation maintains functional elasticity at moderate temperatures while resisting hardening that would reduce lip conformity.

What inspection should be performed during routine maintenance?

Check the sealing lip for abrasion, cracking, and loss of profile, and verify that the outer housing remains seated without radial distortion.
