SKF Nitrile Rubber (NBR) with Steel Element V-Ring Seal Ring Seal, 140 mm ID, 54.5 mm OD

This ring seal provides rotary shaft sealing where a flexible lip element is needed to exclude contaminants and retain lubricants in industrial machinery. It is constructed from a resilient elastomer with an embedded metallic reinforcement and designed for use on shafts of matching diameter. The component’s form and material suit applications in automation and mechanical systems that require a compact, flexible sealing solution.

• Black finish aids Visual inspection and contamination detection
• V-profile lip delivers effective shaft-side exclusion
• Thin cross-section enables installation in constrained housings
• Compatible material reduces chemical swelling in common lubricants

• Suitable for rotating shaft Seals in automation drives
• Ideal for protecting bearings in electric motor assemblies
• Used with gearboxes requiring flexible lip exclusion
• Can be used for sealing spindles in electronics manufacture
• Suitable for retrofitting Seals in mechanical transmission units

It is sized for a 25mm shaft and designed to fit closely to that nominal bore for effective lip contact.

The steel insert provides structural support to maintain profile under dynamic axial forces and reduces deformation at operating speed.

The nitrile rubber compound offers resistance to common oils and greases while limiting swelling from hydrocarbon exposure.

The seal’s outside dimension measures 54.5mm, which should be accounted for when machining the receiving recess.

The component has a cross-sectional thickness of 10.8mm, enabling tight axial packaging while retaining lip flexibility.
