SKF Radial Shaft Seal, 55mm Inside Diameter, 85mm Outside Diameter - 55X85X10 HMSA10 RG

This radial shaft seal provides a rotary sealing Interface designed to prevent fluid leakage around rotating shafts in mechanical assemblies. It is intended for use where a resilient lip is required to maintain contact with a shaft while compensating for minor shaft movement and ensuring separation between internal and external environments.

Features and Benefits:

• Made from nitrile rubber NBR for oil resistance and longevity
• Rotary lip design maintains consistent shaft contact during rotation
• Ten millimetre section thickness reduces extrusion risk under pressure
• Designed for dynamic sealing to limit lubricant loss during operation
• Suited to repeated start‑stop and continuous rotational cycles

Applications

• Suitable for sealing small electric motors and gearboxes
• Ideal for pump shaft sealing in light industrial equipment
• Used with rotating drives in agricultural machinery
• Can be used for maintenance replacement on workshop machinery
• Suitable for installations requiring oil‑resistant shaft Seals

What shaft size does it fit internally?

It fits shafts with a 55 mm inner diameter.

What external housing bore is required for installation?

It requires an 85 mm outer diameter housing bore.

How thick is the sealing cross‑section for installation clearance?

The sealing element has a 10 mm thickness.

What material composes the lip and body of the seal?

The component is manufactured from nitrile rubber (NBR).

Is this suitable for rotary sealing applications with oil present?

Yes, the material and design are intended for oil‑resistant rotary sealing.
