SKF Nitrile Rubber (NBR) Radial Shaft Seal, 30 mm ID, 45 mm OD, 8 mm

This radial shaft seal is designed to prevent fluid leakage and exclude contaminants in rotary assemblies where a sealing lip contacts a rotating shaft. It is suited for use in systems requiring a Compact sealing solution between a shaft and housing, operating where oil resistance and moderate thermal performance are needed.

• Nitrile rubber construction offers oil resistance for rotating applications
• Rotary shaft design maintains a dynamic seal during shaft movement
• Thin cross-section reduces radial space requirements in housings
• High-temperature NBR formulation supports elevated operating temperatures
• Robust lip contact minimises ingress of dust and debris

• Suitable for sealing motor shafts with moderate heat exposure
• Used with gearboxes in light industrial equipment
• Ideal for pump shafts handling oil-based lubricants
• Can be used for automotive auxiliary components
• Used for electric motor assemblies requiring Compact Seals

The lip material is nitrile rubber, chosen for compatibility with oil-based fluids and resilience under mechanical wear.

It uses a rotary shaft lip that maintains line contact with the shaft to control leakage during rotation.

The seal has a relatively slim profile, allowing installation where radial clearance is limited.

The NBR composition is formulated for higher temperature endurance compared with standard elastomers, aiding performance in warmer operating conditions.
