SKF Seal, 40mm Inside Diameter, 50mm Outside Diameter - 40X50X8 HMS5 RG
This seal is a rotary shaft sealing component designed to retain fluids and exclude contaminants in rotating equipment. It is manufactured by SKF and constructed from nitrile rubber, making it suited to typical shafts where oil sealing and resistance to common industrial fluids are required.
Features and Benefits:
• Nitrile compound resists hydrocarbons and oils for extended service life
• Rotary design ensures continuous dynamic sealing under rotation
• Thin radial profile minimises space requirements within housings
• Robust material behaviour maintains sealing contact under vibration
• Rotary design ensures continuous dynamic sealing under rotation
• Thin radial profile minimises space requirements within housings
• Robust material behaviour maintains sealing contact under vibration
Applications
• Suitable for industrial gearboxes requiring oil retention
• Ideal for electric motor shaft sealing in automation systems
• Used with pumps to prevent lubricant leakage
• Can be used for bearings in mechanical drives to exclude contaminants

What shaft sizes does it accommodate?
It fits shafts with an internal diameter measuring 40mm, providing a precise interference fit for common metric shaft journals.
What external housing considerations are required for installation?
The housing bore must accept an outer diameter of 50mm to ensure correct seating and radial support during operation.
How thick is the sealing element and why does that matter?
The section thickness is 8mm which helps maintain axial stability and effective lip contact under axial and radial loads.
What material characteristics affect chemical compatibility?
The sealing element is MADE from nitrile rubber (NBR), which offers compatibility with mineral oils and many hydraulic fluids while limiting use with certain solvents and high-temperature media.
