SKF Nitrile Rubber (NBR) Seal, 45 mm ID, 60 mm OD, 8 mm

This seal is a rotary shaft sealing element designed to separate rotating and stationary components, preventing fluid leakage in machinery. It features a rubber outer diameter and a single elastomeric sealing lip with a garter spring to maintain radial load, making it suitable for retaining oil or grease in assemblies that include relative motion between shaft and housing.

• Nitrile rubber lip resists oil and grease exposure
• Garter spring ensures consistent radial sealing force
• Rubber outside diameter simplifies press-fit housing installation
• Accommodates minor shaft misalignment during operation
• Permissible circumferential speed 7.41 m/s supports moderate rpm

• Suitable for sealing bearings in electric motors
• Ideal for gearboxes requiring oil retention
• Used with rotating shafts in automation equipment
• Can be used for maintenance replacement on mechanical drives
• Used for sealing shafts in electrical actuator assemblies

It operates continuously between −40°C and 100°C with short excursions up to 120°C.

It is rated to a maximum rotational speed of 3120 rev/min with a corresponding circumferential speed limit of 7.41 m/s.

The differential load capacity is 0.03 N/mm across the sealing lip.

The lip is MADE from nitrile rubber (NBR), which is compatible with many oils and greases used in industrial equipment.

A thin inner shaft protection sleeve, such as a Speedi-Sleeve, can be used when the shaft surface is worn prior to fitting.
