SKF Radial Shaft Seal, 38mm Inside Diameter, 52mm Outside Diameter - 38X52X7 HMS5 RG

This radial shaft seal provides a rotary sealing solution for shafts where fluid retention and exclusion of contaminants are required. It is constructed from nitrile rubber and designed to operate around rotating shafts, offering a Compact profile suited to common engineering assemblies.

Features and Benefits:

• Nitrile rubber material resists oils and fuels for extended service life
• Rotary seal design maintains contact with shaft during rotation
• 7 mm thickness gives robust axial sealing capability
• Engineered for tight sealing on shafts with close tolerances
• Balanced lip geometry reduces leak paths during shaft movement

Applications

• Suitable for sealing oil in gearboxes and transmissions
• Used with rotating shafts in pumps and motors
• Ideal for maintenance replacement in industrial drives
• Can be used for shaft-end protection in agricultural machinery

What inner shaft size does it fit?

It fits shafts with a 38 mm inner diameter to ensure correct lip engagement.

What external housing size is required?

The seal requires a 52 mm outer diameter bore for proper seating.

How thick is the sealing element for axial clearance planning?

The sealing element measures 7 mm thickness for axial space calculation.

What compound is the lip MADE from and why is it chosen?

The lip is MADE from nitrile rubber chosen for its compatibility with oils.

Is the seal intended for rotary motion or static sealing?

It is designed specifically for rotary shaft sealing applications.
