SKF Nitrile Rubber (NBR) Seal, 80 mm ID, 125 mm OD, 12 mm

This seal is a rotary shaft sealing component designed to prevent fluid leakage and exclude contaminants in rotating assemblies within industrial equipment. It is intended for use on shafts where a resilient lip material is required to maintain dynamic sealing performance in mechanical and automated systems.

• Nitrile elastomer delivers abrasion resistance and oil compatibility
• Rotary lip design maintains fluid retention during shaft rotation
• Thickness provides consistent axial engagement under load
• Robust sealing reduces ingress of dust and moisture
• Compatible with standard industrial shaft sizes for easy replacement

• Suitable for hydraulic pump shafts in industrial automation
• Ideal for gearbox output shafts in mechanical drives
• Used with electric motor spindles in production equipment
• Can be used for rotating couplings in electrical/mechanical assemblies

The elastomer is nitrile rubber (NBR), which offers good resistance to mineral oils and greases while remaining flexible over typical operating temperature ranges for industrial machinery.

The flexible sealing lip accommodates minor shaft deflections and cyclical motion, maintaining contact to reduce leakage under small misalignment and vibration conditions.

Check outer and inner diameters and ensure the shaft finish and groove geometry match the replacement, proper seating depth and shaft surface condition are critical for optimal sealing.
