SKF Radial Shaft Seal, 30mm Inside Diameter, 47mm Outside Diameter - 30X47X8 HMS5 RG

This radial shaft seal provides a sealing solution for rotating shafts in mechanical assemblies, designed to prevent fluid leakage and exclude contaminants in rotary applications. It is intended for use where a resilient lip material is required to maintain contact with a moving shaft while operating within typical industrial rotary environments.

Features and Benefits:

• Nitrile rubber material resists common oils and fuels
• Rotary seal design maintains dynamic shaft contact
• 8mm thickness gives robust axial sealing pressure
• Suits 30mm bore shafts for precise fit and centring
• 47mm outer diameter allows secure housing seating

Applications

• Suitable for electric motor shaft sealing in machinery
• Used with gearboxes requiring oil retention under rotation
• Ideal for pumps handling lubricated rotational components
• Can be used for sealing axles in small industrial drives

What material construction provides chemical resistance?

The sealing element is MADE from nitrile rubber which offers resistance to oils and typical lubricants.

How does the seal mount within a housing?

The external diameter is sized to be press-fitted into a bore so it remains located under radial load.

What shaft size must be used for correct operation?

A shaft with a 30mm outer diameter is required to match the seal's internal bore and ensure proper lip contact.

How thick is the sealing section that provides axial pressure?

The radial section measures 8mm in thickness which establishes the axial sealing force.

What external housing dimension should be prepared for installation?

The housing or bore should accommodate a 47mm outer diameter to accept the seal.
