SKF Nitrile Rubber (NBR) Seal, 100 mm ID, 125 mm OD, 12 mm

This radial shaft seal provides a sealing Interface between rotating and stationary components to retain oil or grease in machinery. It features a rubber outer diameter that allows press-fit installation into bores and a single elastomeric lip with a garter spring to maintain contact against the shaft under dynamic conditions.

• Garter spring ensures consistent radial load at speed
• Permissible circumferential speed 11.71 m/s supports higher rpm
• Operates between −40°C to 100°C for varied environments
• Short-term temperature tolerance up to 120°C for transient conditions

• Suitable for sealing rotating shafts in automation drives
• Ideal for electric motor and gearbox assemblies
• Used with rotating shafts in electrical equipment housings
• Can be used for maintenance replacement on mechanical assemblies

It is intended for shafts with a nominal diameter of 100mm and fits into housings designed for a 125mm bore.

The seal is rated to 2,040 r/min maximum rotational speed and a circumferential speed limit of 11.71 m/s.

The sealing lip MADE from nitrile rubber (NBR) offers resistance to common oils and greases used in industrial drive systems.

The flexible elastomeric lip and garter spring design permit accommodation of slight shaft misalignment during operation.

The seal is designed for low pressure differentials and specified at 0.03 N/mm for its sealing performance.
