SKF Radial Shaft Seal, 20mm Inside Diameter, 42mm Outside Diameter - 20X42X10 HMS5 RG

This radial shaft seal provides axial sealing for rotating shafts in machinery, preventing fluid leakage and excluding contaminants during shaft rotation. It is intended for rotary sealing duties where a resilient lip material interfaces with a turning shaft to maintain a lubricant barrier and protect internal components.

Features and Benefits:

• Nitrile elastomer lip provides fuel and oil resistance
• Rotary configuration minimises leakage at rotating interfaces
• 10mm radial thickness resists extrusion under static loads
• Designed for shaft applications to reduce contamination ingress
• Robust material delivers consistent sealing across operating cycles

Applications

• Suitable for maintenance replacement in gearboxes and pumps
• Ideal for automotive rotating assemblies requiring oil retention
• Used with industrial drives where lubricant containment is required
• Can be used for light engineering rotating shafts in machinery
• Suitable for workshop spares stock for routine seal changes

What shaft clearance does the seal accept?

It is intended to run on shafts with an internal bore of 20mm.

What external housing size is required for fitting?

The outer diameter measures 42mm so housings must accommodate a 42mm external seal seat.

What material composes the sealing lip and how does it behave?

The lip is MADE from nitrile rubber which resists common oils and retains flexibility for dynamic sealing.

How thick is the sealing body and why does that matter?

The body thickness is 10mm which helps resist deformation and supports the sealing lip under load.

Is this suitable as a direct replacement for worn rotary oil seals?

It is suitable where dimensions and material properties match the original seal specifications.
