SKF Nitrile Rubber (NBR) Radial Shaft Seal, 38 mm ID, 55 mm OD, 10 mm

This radial shaft seal is a rotary sealing component designed to prevent fluid leakage and exclude contaminants in rotating shaft assemblies. It is manufactured from nitrile rubber to Interface between a rotating shaft and a housing bore, maintaining separation of lubricants and external environments in mechanical systems where a compact, resilient seal is required.

• Nitrile rubber construction provides oil resistance and material resilience
• Rotary shaft seal design supports continuous shaft rotation without leakage
• 10mm thickness offers robust axial sealing in confined assemblies
• 38mm inside diameter enables a snug fit on corresponding shafts
• 55mm outside diameter ensures secure retention within the housing bore

• Suitable for sealing bearings in gearboxes and transmissions
• Used with hydraulic pumps to prevent lubricant loss
• Ideal for rotating shafts in industrial motors and gear drives
• Can be used for maintenance replacement on rotating machinery

Use a flat pressing tool and apply even axial force to seat the seal without deforming the lip.

A smooth shaft finish without deep grooves or burrs is necessary to preserve the sealing lip and prevent premature wear.

The nitrile rubber elastomer is formulated for compatibility with common oil-based lubricants and resisting swelling in such fluids.

Machine the bore to concentric tolerance with a clean, dry surface and chamfer the entry to ease installation.
