SKF Nitrile Rubber (NBR) Seal, 40 mm ID, 72 mm OD, 10 mm

This seal is a rotary shaft seal designed to separate rotating and stationary machine parts and retain lubricants in moving assemblies. It features a rubber outside diameter and a single sealing lip with an auxiliary non‑contacting lip and garter spring to maintain sealing performance in contaminated environments. The component is intended for oil or grease applications across industrial machinery.

• Permissible circumferential speed 6.93 m/s for high‑speed operation
• Operating temperature range −40°C to 100°C for varied environments
• Short‑term temperature tolerance up to 120°C for transient heat events
• Garter spring maintains lip contact to reduce leakage risk
• Dust auxiliary lip improves exclusion of external contamination
• Accommodates shaft misalignment to reduce installation sensitivity

• Suitable for industrial gearboxes requiring oil retention
• Ideal for electric motor shaft sealing in automation systems
• Used with rotating assemblies in mechanical drives
• Can be used for maintenance replacement in pump shafts
• Used for sealing shafts in electrical drive units

It is intended for shafts with a 40mm diameter and is manufactured to suit a 72mm housing bore.

The lip is MADE from NBR nitrile rubber, which offers compatibility with common oils and greases used in industrial applications.

The seal is rated for up to 3,300 rev/min at the specified shaft diameter and speed limits.

The design withstands a pressure differential of 0.03 N/mm while maintaining dynamic sealing.
