SKF Radial Shaft Seal, 30mm Inside Diameter, 46mm Outside Diameter - 30X46X7 HMSA10 RG

This radial shaft seal is a rotary sealing component designed to prevent fluid leakage around rotating shafts in mechanical assemblies. It is manufactured from nitrile rubber (NBR) and suited to applications where a resilient elastomeric contact is required to exclude lubricants and contaminants while the shaft is in motion.

Features and Benefits:

• Nitrile rubber construction offers resistance to common oils and greases
• Rotary design maintains continuous dynamic sealing during shaft rotation
• Robust lip geometry supports sustained contact under radial motion
• Thin cross-section reduces space requirement in housing bores
• Compatible with metric shaft installations for straightforward integration

Applications

• Suitable for sealing shafts in general machinery
• Ideal for use in gearboxes with moderate oil exposure
• Used with pump assemblies requiring rotating sealing faces
• Can be used for motor shaft protection against contaminants
• Suitable for bearing housing lubrication retention

What material properties affect chemical compatibility?

The elastomer composition provides resistance to mineral oils and greases and determines compatibility with various fluids.

How does the seal cope with shaft misalignment?

The flexible lip tolerates minor radial run-out by maintaining contact with the shaft surface under rotation.

What installation considerations reduce leakage risk?

Correct press-fit in the housing bore and a clean, undamaged shaft finish reduce extrusion and ensure uniform lip contact.

How does temperature influence sealing performance?

Operating temperature alters elastomer flexibility, elevated temperatures will increase material softness and affect lip sealing force.

What maintenance practice extends service life?

Regular inspection for wear and replacing the seal when lip deformation or hardening is observed prevents progressive leakage.
