SKF Nitrile Rubber (NBR) Seal, 35 mm ID, 72 mm OD, 10 mm

This seal is a rotary shaft seal designed to separate rotating and stationary machine elements, preventing lubricant escape and ingress of contaminants in dynamic assemblies. It features a rubber outer diameter with a single elastomeric sealing lip and an auxiliary non‑contacting lip, making it suitable for environments where oil or grease retention and contaminant exclusion are required.

• Garter spring ensures consistent radial load and improved lip contact
• Auxiliary non‑contacting lip enhances dust exclusion in polluted environments
• Nitrile rubber lip offers compatibility with oil and grease media
• Accommodates shaft misalignment to reduce sealing failures
• Permits circumferential speeds up to 6.39 m/s for rotational usage
• Withstands operating temperatures from −40°C to 100°C

• Suitable for sealing shafts in automation gearboxes and drives
• Ideal for rotating actuators in electrical equipment enclosures
• Used with bearings in mechanical transmission assemblies
• Can be used for oil retention in industrial motors and pumps

It is MADE for shafts of 35mm diameter and housings with a 72mm bore.

Short‑duration temperature excursions may reach 120°C without immediate failure.

The design supports rotational speeds up to 3,480 rpm under specified conditions.

It can operate with a small pressure differential of around 0.03 N/mm.

The outside diameter is rubber with metal reinforcement to provide a secure housing fit.
