SKF Radial Shaft Seal, 55mm Inside Diameter, 72mm Outside Diameter - 55X72X8 HMS5 RG

This radial shaft seal is a rotary sealing component designed to prevent fluid leakage and exclude contaminants in rotating assemblies. It is intended for use where a compact, resilient sealing element is required around a rotating shaft, offering a balance of material flexibility and dimensional conformity for routine industrial and automotive service conditions.

Features and Benefits:

• Nitrile rubber material offers resistance to common oils and greases
• Rotary design maintains contact under shaft rotation for continuous sealing
• 8mm thickness provides a robust sealing lip for wear resistance
• 55mm inside diameter ensures secure fit on corresponding shafts
• 72mm outside diameter supports press-fit installation into housings

Applications

• Suitable for automotive driveline and gearbox sealing tasks
• Ideal for light industrial rotating equipment maintenance
• Used with shafts requiring oil retention in mechanical assemblies
• Can be used for replacing worn lip Seals in service kits
• Used for routine refurbishment of rotating housings in workshops

How should it be installed to avoid seal damage?

Use a concentric press-fit tool and apply even axial force to the outside diameter to prevent lip distortion.

What behaviour is expected under moderate shaft speed?

The sealing lip maintains contact during rotation, providing continuous exclusion of contaminants and retention of lubricants at typical service speeds.

How does the material respond to typical hydrocarbon lubricants?

The nitrile rubber construction exhibits compatibility with common mineral oils and greases, preserving elasticity and sealing function.

What tolerances are important for shaft and housing preparation?

Ensure the shaft surface roughness and roundness match typical seal installation standards and that the housing bore diameter matches the outside diameter for secure seating.
