SKF Radial Shaft Seal, 75mm Inside Diameter, 100mm Outside Diameter - 75X100X12 HMS5 RG

This radial shaft seal provides fluid retention and contaminant exclusion for rotary shafts in mechanical assemblies. It is intended for use where a sealing element must run against a rotating journal to maintain lubrication and prevent ingress, suited to industrial shaft sealing applications.

Features and Benefits:

• Nitrile rubber material resists common oils and greases
• Rotary seal design accommodates shaft rotation and axial movement
• 12mm thickness offers robust contact and sealing engagement
• Durable construction supports continuous shaft operation
• Compatibility with standard shaft housings simplifies replacement

Applications

• Suitable for industrial gearboxes requiring oil retention
• Used with bearings to prevent lubricant leakage
• Ideal for rotating pump shafts in fluid systems
• Can be used for motor shaft sealing in machinery
• Suitable for maintenance replacement in plant equipment

What are the key material properties relevant to sealing oils?

The lip is formed from nitrile rubber which provides resistance to petroleum-based lubricants and typical industrial greases.

How does the seal integrate with existing shaft assemblies?

It fits over a rotating journal and runs with radial contact to retain lubricant and exclude contaminants from the bearing interface.

What thickness characteristics affect service life?

A 12mm cross-section increases contact area and structural support, helping maintain lip conformity under operating loads.

How should the component be matched to a shaft for replacement?

Select a seal with the same internal and external dimensions and material so the lip fits the shaft diameter and housing bore for proper sealing.

What operational behaviour is expected during continuous rotation?

The rotary lip maintains a dynamic seal during shaft rotation while allowing axial and slight radial movement without losing retention.
