SKF Nitrile Rubber (NBR) Radial Shaft Seal, 25.4 mm ID, 31.75 mm OD

This radial shaft seal provides a sealing solution for rotating shafts in industrial equipment, preventing fluid leakage and contamination ingress within mechanical assemblies. It is constructed from nitrile rubber and is suitable for use across a broad temperature range in automation, electrical and mechanical systems.

• Nitrile rubber composition resists common oils and greases • Operates up to 100°C enabling high-temperature processes • Functions down to -40°C for low-temperature environments • Meets ISO 6194 for standardised shaft sealing performance • Conforms to DIN 3760 for dimensional and functional compatibility • Thin profile offers Compact installation without compromise

• Suitable for sealing rotating shafts in automation drives • Ideal for bearing housings in electronic cooling fans • Used with gearboxes in light mechanical equipment • Can be used for oil containment in electrical motor assemblies • Used for replacement sealing in industrial maintenance tasks

The sealing lip is formed from nitrile rubber which offers resistance to many mineral oils and greases commonly used in industrial gearboxes and motor bearings.

Its elastomeric properties maintain flexibility from -40°C up to 100°C, preserving sealing contact and preventing hardening or excessive swelling within that range.

The component is produced to comply with ISO 6194 and DIN 3760, which align dimensions and functional requirements for shaft Seals used in European industrial equipment.

The lip geometry and material resilience sustain consistent contact against the shaft surface, reducing particulate ingress and protecting internal components during rotation.
