SKF Radial Shaft Seal, 8mm Inside Diameter, 18mm Outside Diameter - 8X18X5 HMS5 RG

This radial shaft seal is a rotary sealing component designed to prevent lubricant leakage and exclude contaminants in rotating assemblies. It is intended for use where a Compact sealing solution is required around a rotating shaft, providing a tight Interface between the shaft and housing in confined assemblies.

Features and Benefits:

• Nitrile rubber construction provides oil resistance and flexible sealing
• Rotary design supports continuous shaft rotation without fluid loss
• Thin cross-section aids installation in restricted axial spaces
• Precision form delivers consistent contact and minimal leakage
• Suitable for small-bore applications requiring Compact sealing

Applications

• Suitable for miniature gearboxes and micro transmissions
• Used with small electric motors and actuators
• Ideal for handheld power tools with rotating shafts
• Can be used for precision instrumentation rotary Seals
• Used for Compact pumps and miniature hydraulic units

What material characteristics affect chemical compatibility?

The sealing lip is MADE from nitrile rubber which offers resistance to common mineral oils and greases while providing good elasticity for dynamic sealing.

How should the seal be installed relative to the shaft surface?

It should be pressed squarely into the housing bore so the sealing lip makes uniform contact with the shaft to prevent uneven wear.

What shaft fit considerations improve service life?

A smooth, correctly sized shaft with minimal runout reduces lip wear and maintains a stable sealing Interface during rotation.

How does seal thickness influence axial space requirements?

The 5 mm section thickness reduces the axial envelope, allowing use where clearance is limited without altering radial sealing performance.
