SKF Nitrile Rubber (NBR) Seal, 25 mm ID, 42 mm OD, 6 mm

This radial shaft seal is designed to separate rotating and stationary machine components, retaining lubricants and excluding contaminants in industrial equipment. It employs an elastomeric sealing lip and a non-contacting auxiliary lip to maintain protection in environments with oil, grease and particulate exposure, making it suitable for use in automated and mechanical systems where reliable shaft sealing is required.

• Garter spring maintains consistent lip contact under shaft movement
• Auxiliary dust lip improves exclusion of external contamination
• Rubber outside diameter ensures secure housing fit and vibration damping
• Accommodates shaft misalignment to reduce wear and leakage
• High pumping rate supports effective fluid control at speed

• Suitable for oil-sealed rotary bearings in automation systems
• Ideal for gearbox and motor shaft sealing in electrical drives
• Used with rotating assemblies in electronics cooling fans
• Can be used for sealing greased shafts in mechanical plant

It operates continuously from −40°C up to 100°C with short excursions to 120°C.

It functions up to a circumferential speed of 5.03 m/s and a rotational speed of 3,840 r/min.

The auxiliary non-contacting lip reduces ingress of dust and debris, preserving primary lip integrity.

It handles a pressure differential of 0.03 N/mm, suitable for low-pressure shaft sealing tasks.

The sealing lip is MADE from nitrile rubber (NBR) to provide oil and grease compatibility.
