SKF Nitrile Rubber (NBR) Seal, 30 mm ID, 52 mm OD, 10 mm

This radial shaft seal is designed to provide a sealed Interface between rotating and stationary components in mechanical and electromechanical equipment. It uses a nitrile elastomer lip and a rubber outer diameter to maintain fluid retention and exclude contaminants in systems running with oil or grease, suitable for applications where a non-contacting auxiliary lip and spring-loaded sealing are advantageous.

• Nitrile lip provides oil resistance and wear performance
• Garter spring maintains consistent contact pressure
• Rubber outside diameter enables secure housing fit
• Operates up to 100°C with short peaks to 120°C
• Permissible circumferential speed 5.77 m/s supports moderate shaft speeds

• Suitable for sealing shafts in industrial gearboxes
• Ideal for bearings in automation equipment
• Used with electric motor drives requiring oil sealing
• Can be used in servo assemblies subject to contamination

It is intended for shafts with a 30mm nominal diameter.

It is rated for rotational speeds up to 3,660 r/min.

The seal withstands a differential of 0.03 N/mm across the sealing lip.

The sealing lip is MADE from nitrile rubber and the outside diameter is rubber with metal reinforcement.

Yes, the combination of an auxiliary non-contacting lip and a garter spring helps accommodate misalignment and improves performance in polluted environments.
