SKF Radial Shaft Seal, 30mm Inside Diameter, 55mm Outside Diameter - 30X55X10 HMSA10 RG

This radial shaft seal provides a sealing solution for rotating shafts, designed to prevent fluid leakage and exclude contaminants in rotary assemblies. It is intended for applications where a polymer lip contacts a moving shaft to maintain oil retention and environmental exclusion during shaft rotation.

Features and Benefits:

• Nitrile rubber construction resists common oils and greases
• Rotary lip geometry supports continuous shaft motion
• 10mm wall section offers robust axial sealing force
• 30mm inside diameter enables tight shaft conformity
• 55mm outside diameter allows secure housing fit

Applications

• Suitable for sealing rotating shafts in gearboxes
• Ideal for oil retention in pump assemblies
• Used with motor shafts requiring oil exclusion
• Can be used for maintenance replacements in industrial drives
• Suitable for use where contaminant exclusion is required

What material composes the sealing lip and why is it chosen?

The lip is MADE from nitrile rubber which provides compatibility with petroleum-based lubricants and general-purpose hydraulic fluids.

How should the component be installed to ensure correct sealing?

It should be pressed into the housing bore evenly so the outside diameter seats uniformly and the inner lip contacts the shaft without distortion.

What shaft size tolerance should be considered for optimal performance?

The inside diameter is specified at 30 mm, so a matching shaft diameter with minimal radial runout and appropriate interference ensures effective lip contact.

How does the seal accommodate rotary motion during operation?

The design relies on a flexible elastomer lip that maintains contact with the rotating shaft, creating a dynamic barrier against fluid escape and ingress.
