SKF Nitrile Rubber (NBR) Seal, 85 mm ID, 110 mm OD, 12 mm

This is a radial rotary shaft seal designed to separate rotating and stationary components and retain lubricants in machines. It features a rubber outside diameter and a single elastomer sealing lip with a garter spring to maintain contact, making it suitable for moderate-speed rotating shafts operating across a wide temperature range.

• Nitrile lip material gives resistance to mineral oils and greases
• Garter spring maintains consistent radial load for sealing integrity
• Accommodates misalignment to reduce leakage risk under shaft runout
• Permissible circumferential speed 9.99 m/s enabling moderate-speed applications
• Operating temperature range −40°C to 100°C supporting varied environments
• Short-term temperature tolerance up to 120°C for occasional thermal excursions

• Suitable for gearbox lubricant retention in automation equipment
• Ideal for motor shafts in electrical drive systems
• Used with industrial actuators in mechanical assemblies
• Can be used for bearing protection in electronic cooling fans
• Used for sealing oil in rotating components of conveyors

It is rated for up to 2220 r/min under specified installation and operating conditions.

The seal tolerates a pressure differential of 0.03 N/mm when installed correctly in a housing bore and on a shaft with appropriate surface finish.

The design fits a housing bore of 110mm when the seal is pressed into place.

A thin-walled speedi-sleeve accessory is listed as an associated product for worn or damaged shafts.
