SKF Radial Shaft Seal, 65mm Inside Diameter, 120mm Outside Diameter - 65X120X12 HMSA10 RG

This radial shaft seal provides a rotational sealing Interface designed to prevent fluid leakage and exclude contaminants in rotary assemblies. It is intended for installations where a resilient sealing lip and resistance to common hydrocarbon-based fluids are required, operating as a shaft-mounted seal between rotating and stationary components.

Features and Benefits:

• Nitrile rubber construction resists many oil-based fluids
• Rotary seal form reduces leakage at rotating interfaces
• 12mm cross-section offers robust axial sealing contact
• Designed for continuous shaft rotation under normal conditions
• Compatible with standard shaft bore installations requiring lip Seals

Applications

• Suitable for gearboxes requiring fluid retention at shafts
• Ideal for pump drives handling lubricated media
• Used with motor shafts in industrial drivetrains
• Can be used for rotary couplings in factory equipment
• Appropriate for refurbishment of rotating machine Seals

What material properties influence chemical resistance?

The elastomer is nitrile rubber which provides resistance to many hydrocarbon oils and greases.

How should shaft and housing tolerances be prepared for installation?

Machined bore and shaft surfaces should be concentric and smooth to ensure correct interference and sealing lip contact.

What physical role does the 12mm thickness perform during operation?

The 12mm cross-section maintains axial lip pressure and accommodates minor shaft misalignment while preserving sealing contact.

Which diameters must match mating components for correct fit?

The internal diameter must match the shaft diameter while the external diameter must correspond to the housing bore for proper seating.

How does the seal cope with particulate ingress at rotary interfaces?

The lip profile and resilient material act to exclude contaminants from the lubricated sealing zone during rotation.
