SKF Nitrile Rubber (NBR) Radial Shaft Seal, 45 mm ID, 72 mm OD, 10 mm

This radial shaft seal provides a sealing Interface for rotating shafts, designed to prevent fluid leakage and exclude contaminants in industrial rotary assemblies. It is constructed from nitrile rubber and suited for environments requiring a flexible contact seal around a shaft while retaining lubricants and resisting ingress of dirt and debris.

• Nitrile rubber composition offers resistance to mineral oils
• Rotary configuration supports continuous shaft movement
• 10mm wall section sustains contact pressure under load
• Flexible lip design maintains sealing on eccentric shafts
• Elastomeric construction tolerates routine thermal cycling

• Suitable for gearboxes with rotating output shafts
• Used with pumps handling lubricated shafts
• Ideal for electric motor shaft sealing tasks
• Can be used for agricultural machinery drivetrains
• Suitable for general industrial rotating equipment

It fits shafts sized for a 45mm internal bore and should be installed on a shaft matching that diameter to ensure correct lip contact.

The housing should accept an outer diameter of 72mm to allow proper interference fit and secure seating of the seal.

The radial section is 10mm thick which preserves axial stability and maintains effective contact under side loads.

The elastomer is nitrile rubber, which is selected for its compatibility with common mineral-based lubricants and oils.
