SKF Nitrile Rubber (NBR) Seal, 60 mm ID, 85 mm OD, 8 mm

This seal is a rotary shaft oil seal designed to separate rotating and stationary components and to retain lubricants in machinery. It features an elastomeric sealing lip and a rubber outer diameter to provide a contact Interface with the housing while maintaining a non‑contacting auxiliary lip for improved exclusion of contaminants. The design includes a garter spring to maintain effective lip pressure around the shaft in polluted environments.

• Permits circumferential speed up to 8.58 m/s for high‑speed shafts
• Withstands operating temperatures from -40°C to 100°C
• Garter spring ensures consistent lip force during rotation
• Auxiliary dust lip increases resistance to external contamination
• Accommodates shaft misalignment for flexible installation

• Suitable for gearbox output shafts requiring oil retention
• Ideal for motor‑driven pumps in industrial automation
• Used with rotating assemblies in electrical drive systems
• Can be used for bearings in mechanical manufacturing equipment

It is rated to operate up to 2,760 r/min, matching the permissible surface speed limit.

The material permits short‑duration exposure up to 120°C without permanent alteration of sealing performance.

The outer diameter is rubberised and metal reinforced, so a closely matched bore at 85mm provides a press‑fit seating surface.

The lip is MADE from nitrile rubber (NBR), offering compatibility with oil and grease and resistance to common industrial lubricants.
