SKF Nitrile Rubber (NBR) Radial Shaft Seal, 48 mm ID, 70 mm OD, 10 mm

This radial shaft seal is a rotary sealing component designed to prevent fluid leakage and exclude contaminants around rotating shafts in mechanical systems. Constructed from nitrile rubber, it operates as an oil-retaining Interface between a shaft and housing, suitable for standard rotary sealing duties in industrial equipment where a resilient elastomeric lip contact is required.

• Nitrile rubber construction resists common oils and greases
• Rotary lip design maintains dynamic shaft contact under rotation
• 10mm radial thickness provides robust axial sealing force
• Seated on shafts with 48mm inner diameter for secure fit
• Profiles to Interface with 70mm outer housings for stable seating

• Suitable for sealing transmission and gearbox assemblies
• Used with motor shafts in factory machinery
• Ideal for rotating pump and compressor shafts
• Can be used for maintenance replacement in conveyors
• Suitable for bearing housing oil retention tasks

The elastomer is nitrile rubber so it is compatible with many mineral oils and greases commonly used in industrial systems.

It is press‑fitted into a housing bore sized to the 70mm outer diameter and slid over a 48mm shaft until the sealing lip engages the rotating surface.

The 10mm thickness provides axial rigidity that helps maintain contact pressure and prolongs lip conformity under rotational wear.

The elastomeric lip offers limited tolerance to minor shaft run‑out and angular misalignment while preserving sealing contact.
