SKF Radial Shaft Seal, 20mm Inside Diameter, 35mm Outside Diameter - 20X35X8 HMSA10 RG


This radial shaft seal provides a sealing Interface for rotating shafts in machinery, preventing fluid escape and ingress within bearing housings and similar assemblies. Constructed from nitrile rubber, it is suited to applications requiring resistance to common oils and lubricants while maintaining a continuous running fit around a rotating shaft.

Features and Benefits:


• Nitrile rubber construction resists common lubricants and oils
• Rotary seal design maintains a dynamic shaft Interface
• 8mm thickness supports sustained axial sealing contact
• 20mm inside diameter enables tight bore engagement
• 35mm outside diameter ensures secure housing fit

Applications


• Suitable for sealing motors with small bore shafts
• Used with gearboxes requiring oil containment
• Ideal for rotating pump shaft sealing tasks
• Can be used for reduction gear and actuator shafts

What material properties determine fluid compatibility?


The sealing lip is formed from nitrile rubber which offers resistance to a range of oils and lubricants and is chosen for dynamic sealing against shaft surfaces.

How should the internal bore be prepared before installation?


The housing bore should be clean, free of burrs and slightly larger than the outside diameter to allow a press fit without deforming the seal.

What is the correct shaft fit for optimal performance?


The shaft should match the 20mm internal diameter closely with minimal radial run-out to preserve the sealing lip contact and reduce wear.

How does thickness affect axial performance?


The 8mm cross-section provides sufficient axial bulk to maintain contact pressure and accommodate minor axial movement without Rapid compression set.
