SKF Nitrile Rubber (NBR) Seal, 30 mm ID, 42 mm OD, 6 mm

This radial rotary shaft seal is designed to separate rotating and stationary components, preventing loss of lubricant and ingress of contaminants in rotating assemblies. It features a rubber outer diameter and a single elastomeric sealing lip with an auxiliary non-contacting lip and garter spring to maintain effective shaft contact in polluted environments. The seal is suitable for oil or grease sealing tasks within mechanical and automation systems.

• Auxiliary non-contacting lip improves contamination exclusion
• Garter spring maintains consistent lip pressure at speed
• Rubber outer diameter allows secure press-fit in housings
• Withstands circumferential speeds up to 5.77 m/s
• Operates across −40°C to 100°C continuous temperatures

• Suitable for bearings in automation drive units
• Ideal for electric motor shaft protection in electronics equipment
• Used with gearboxes requiring grease retention
• Can be used for rotating shafts in industrial pumps

It fits shafts with a diameter of 30mm, providing a close-running contact surface for effective sealing.

It tolerates short periods up to 120°C without immediate material failure, enabling brief thermal excursions during operation.

The seal supports rotational speeds up to 3,660 r/min while maintaining sealing performance at the specified circumferential speed.

The primary lip is MADE from nitrile rubber (NBR) and the outside is rubber-reinforced for housing retention.

A thin-walled sleeve such as the compatible Speedi-Sleeve can be used where shaft repair or local sleeve fitting is required.
