SKF Radial Shaft Seal, 70mm Inside Diameter, 12mm Thickness - 70X90X12 HMS5 RG

This radial shaft seal provides a sealing solution for rotary shafts where a resilient contact element is required to retain lubricants and exclude contaminants during rotation. It is constructed from nitrile rubber and intended for use where a flexible elastomeric barrier is needed between rotating and stationary components.

Features and Benefits:

• Nitrile rubber composition resists common oils and greases
• Rotary design maintains continuous dynamic sealing under rotation
• 12mm section thickness supports sustained axial contact pressure
• Designed to fit 70mm internal shafts for secure seating
• Compatible with 90mm housing bores for straightforward installation

Applications

• Used with industrial motors requiring oil retention
• Suitable for gearbox shafts operating under moderate temperatures
• Ideal for pumps where rotating Seals prevent leakage
• Can be used for drive shafts in light machinery
• Used for maintenance replacement of worn shaft Seals

What material determines chemical compatibility?

The seal is formed from nitrile rubber which offers resistance to typical oils and greases.

Which shaft and bore sizes must match for correct fitment?

The internal diameter accepts 70mm shafts while the external diameter seats in 90mm bores.

How does the seal cope with axial loading at the shaft interface?

The 12mm section thickness provides the axial cross-section necessary to maintain sealing contact under axial loads.

Is the component suitable for dynamic rotary sealing applications?

Yes, the design is intended specifically for rotary shaft sealing during continuous rotation.
