SKF Radial Shaft Seal, 20mm Inside Diameter, 42mm Outside Diameter - 20X42X10 HMSA10 RG

This radial shaft seal provides a rotary sealing solution designed to prevent fluid leakage around rotating shafts in mechanical assemblies. It is manufactured from nitrile rubber and intended for use where a resilient, oil-resistant sealing element is required between a shaft and housing during rotation.

Features and Benefits:

• Nitrile rubber material offers resistance to common lubricants
• Rotary shaft design reduces leakage at rotating interfaces
• Compact cross-section supports confined installation spaces
• Durable lip geometry maintains contact under axial movement

Applications

• Suitable for sealing rotating shafts in gearboxes
• Used with light-duty pumps requiring oil containment
• Ideal for bearing housings with moderate shaft speeds
• Can be used for general machine-tool spindle sealing

What shaft sizes does it accommodate?

It matches a shaft with a 20 mm diameter.

What housing bore size is required for installation?

A housing bore of 42 mm is required to locate it correctly.

How thick is the sealing element overall?

The radial profile measures 10 mm in thickness.

What material composes the sealing lip?

The lip is formed from nitrile rubber providing elastic sealing properties.

Is this suitable for use as an oil seal in rotating equipment?

Yes, it is designed to act as an oil seal in rotary applications.
