SKF Nitrile Rubber (NBR) Seal, 65 mm ID, 85 mm OD, 12 mm

This seal is a rotary shaft seal designed to separate rotating and stationary machine parts and to retain lubricants while excluding contaminants. It features a rubber outer diameter and a single primary sealing lip combined with an auxiliary non‑contacting lip and a garter spring to maintain contact with the shaft in polluted conditions.

• Nitrile construction resists oil and grease exposure during operation
• Garter spring maintains sealing contact under shaft vibration
• Auxiliary non‑contacting lip improves contaminant exclusion
• Designed to tolerate slight shaft misalignment without failure
• High pumping rate enhances lubricant retention at speed

• Suitable for hydraulic and gearbox assemblies requiring oil retention
• Ideal for rotating motors and pumps in automation equipment
• Used with industrial drives subject to dust and particulate ingress
• Can be used for maintenance replacement in mechanical assemblies

The lip is MADE from nitrile rubber (NBR), selected for resistance to oils and greases and for its reliable elastic sealing behaviour at typical industrial temperatures.

The seal design accommodates slight misalignment by combining elastic lip material with a garter spring that preserves radial contact despite minor shaft eccentricity.

Yes, a dedicated auxiliary lip provides non‑contact protection that reduces ingress of dust and debris while the main lip handles fluid retention.

The outer diameter is formed from elastomeric material to ensure an interference fit in housing bores and to absorb small housing bore variations.
