SKF Nitrile Rubber (NBR) Seal, 50 mm ID, 62 mm OD, 7 mm

This seal is a rotary shaft sealing component designed to prevent fluid leakage and exclude contaminants in rotating assemblies. It is intended for use where a resilient sealing lip is required between a shaft and housing, offering compatible material properties for typical industrial environments encountered in automation, electronics, electrical and mechanical systems.

• Nitrile rubber construction resists oils and greases, enhancing service life
• Rotary shaft configuration maintains dynamic sealing under rotation
• 7mm cross-section supports robust axial contact and stability
• Designed for 50mm bore compatibility enabling precise shaft fit
• 62mm outer diameter ensures secure housing retention

• Suitable for hydraulic actuator shafts in automation systems
• Ideal for bearings in electrical motor assemblies
• Used for rotary couplings in mechanical drives
• Can be used for sealing shafts in electronic cooling fans

The elastomer is nitrile rubber (NBR), which provides good compatibility with mineral oils and common lubricants used in industrial machinery.

Ensure the shaft diameter matches the specified bore and that the housing bore closely conforms to the outer diameter to achieve correct interference and prevent extrusion.

It is intended for rotary applications where the sealing lip remains in sliding contact with a rotating shaft.

The 7mm thickness gives axial rigidity that aids correct seating and sustained contact pressure during service.
