SKF Radial Shaft Seal, 40mm Inside Diameter, 72mm Outside Diameter - 40X72X7 HMSA10 RG

This radial shaft seal is a rotary sealing element designed to prevent fluid leakage and exclude contaminants in rotating shaft assemblies, suitable for standard industrial shaft sealing tasks where a robust elastomeric lip is required.

Features and Benefits:

• Nitrile rubber construction resists common oils and greases
• 7 mm cross-section provides Durable sealing pressure
• Rotary shaft design maintains contact at rotational interfaces
• 40 mm internal fit secures onto shafts with concentric stability
• 72 mm external fit integrates with housings for firm seating

Applications

• Suitable for sealing rotating shafts in industrial machinery
• Used with gearboxes requiring oil retention at the shaft Interface
• Ideal for pump shafts operating with lubricants
• Can be used for motor shaft protection against contaminants
• Used for shaft replacements needing matching outside dimensions

What material characteristics affect compatibility with lubricants?

The elastomer is nitrile rubber (NBR), which offers resistance to many oils and greases and provides elastic recovery under shaft movement.

How should I select a replacement based on shaft fit?

Choose one with an internal diameter of 40 mm to match the shaft journal for correct interference fit and radial alignment.

What housing considerations are important for installation?

Ensure the bore accommodates a 72 mm outer diameter to achieve correct seating and avoid lip deformation during press-fit installation.

How does the seal thickness influence operational performance?

A 7 mm thickness delivers adequate radial stiffness to maintain contact under typical shaft rotation while allowing minor shaft misalignment.
