SKF Nitrile Rubber (NBR) Radial Shaft Seal, 80 mm ID, 110 mm OD, 10 mm

This radial shaft seal provides a sealing Interface for rotary shafts in rotating equipment where oil retention and contaminant exclusion are required. It is constructed from nitrile rubber and is intended for use on shafts with a specified internal clearance, offering a straightforward solution for maintaining lubrication and preventing ingress in industrial rotary assemblies.

• Nitrile rubber construction resists common mineral oils
• Rotary design reduces leakage during shaft rotation
• Durable 10mm section thickness supports axial load distribution
• 80mm inner diameter ensures accurate shaft fitment
• 110mm outer diameter offers stable housing engagement

• Suitable for rotating pumps and gearboxes in factories
• Used with motor-driven fans and blowers in plants
• Ideal for sealing shaft ends on industrial compressors
• Can be used for rotating couplings and drive assemblies
• Used for maintenance replacement in production-line equipment

Nitrile rubber provides resistance to many mineral-based oils and greases while maintaining flexibility at typical operating temperatures.

The shaft must be machined to the specified inner-diameter tolerance to ensure an interference fit and prevent axial slippage.

The bore accepting the outer diameter must be concentric and sized to receive the seal’s outside dimension for even compression and retention.

The 10mm cross-section distributes axial forces across the seal lip, reducing deformation and helping preserve sealing contact over time.
