SKF Nitrile Rubber (NBR) Seal, 24 mm ID, 35 mm OD, 7 mm

This seal is a rotary shaft sealing element designed to separate rotating and stationary machine parts and retain lubricants in dynamic assemblies. It features a flexible sealing lip formed from nitrile rubber and an elastomeric outer diameter that adapts to a housing bore, providing a Compact solution for oil or grease retention in mechanical systems.

• Garter spring maintains consistent radial load for sealing integrity
• Permissible circumferential speed 4.86m/s supports moderate shaft speeds
• Operating temperature range −40°C to 100°C suits varied environments
• Short-term temperature tolerance up to 120°C allows occasional heat spikes
• Accommodates shaft misalignment to reduce leakage risk
• Rubber outside diameter reduces need for interference-fit housings

• Suitable for sealing rotating shafts in automation actuators
• Ideal for retaining lubricant in electric motor assemblies
• Used with bearings where Compact oil sealing is required
• Can be used for shaft protection in small gearboxes
• Used for maintenance replacements in industrial drives

It is designed to fit a shaft diameter of 24mm and a housing bore of 35mm.

The maximum recommended rotational speed is 3,840 r/min based on circumferential speed limits.

The seal is rated for a pressure differential of 0.03 N/mm across the sealing lip.

The lip is MADE from nitrile rubber (NBR), chosen for compatibility with oil and grease and resistance to wear.

A thin protective sleeve can be used to restore worn shaft surfaces prior to fitting to prevent premature lip damage.
