SKF Radial Shaft Seal, 40mm Inside Diameter, 6mm Thickness - 40X52X6 HMS5 RG

This radial shaft seal is a rotary sealing component designed to prevent lubricant leakage and exclude contaminants in rotating shaft assemblies. It is manufactured from nitrile rubber and intended for axial installation to maintain fluid separation between housing and shaft interfaces in industrial rotating equipment.

Features and Benefits:

• Nitrile rubber material offers oil resistance for extended service life
• Rotary seal design minimises leakage under rotational motion
• Robust 6mm cross-section supports pressure containment in housings
• Engineered for rotating shafts to reduce contamination ingress

Applications

• Suitable for Seals on rotating transmission shafts
• Used with pumps requiring fluid retention around shafts
• Ideal for gearboxes operating with lubricated bearings
• Can be used for rotating couplings in machinery assemblies

What shaft-to-housing fit is necessary for reliable sealing?

A precise interference fit between shaft and housing bore is required to maintain radial compression and ensure the seal lip contacts the shaft uniformly.

How does the material behave with standard lubricants?

The nitrile rubber formulation is compatible with common mineral oils and provides resistance to swelling and softening when exposed to such lubricants.

What maintenance considerations apply to the seal in service?

Regular inspection of the sealing lip for wear and verification of lubricant condition are recommended to detect deterioration before leakage occurs.

How is the seal oriented during installation to function correctly?

The lip should face the fluid side so the sealing edge contacts the rotating surface and prevents fluid migration toward the environment.
