SKF Seal, 45mm Inside Diameter, 58mm Outside Diameter - 45X58X7 HMSA10 RG

This seal serves as a rotary shaft sealing element designed to prevent fluid leakage and exclude contaminants in rotating assemblies within industrial equipment. It is intended for use where a resilient lip material is required to maintain contact with a shaft while operating in mechanical and electromechanical systems.

Features and Benefits:

• Nitrile rubber construction resists oil and hydrocarbons • Rotary shaft design maintains dynamic sealing under rotation • 7mm section thickness gives stable axial support • 45mm bore ensures accurate shaft fit for consistent sealing • 58mm outer form fits housings with minimal play

Applications

• Suitable for hydraulic pump shaft sealing in automation • Ideal for motor and gearbox rotary sealing in electronics manufacturing • Used with rotating bearings in electrical motor assemblies • Can be used for shaft sealing in mechanical transmission systems

What material properties affect chemical compatibility?

The lip compound is nitrile rubber which offers resistance to many oils and common hydrocarbons but has limited compatibility with strong acids, ketones and certain fuels.

How does the seal accommodate shaft runout or misalignment?

The flexible elastomeric lip tolerates small radial runout and light misalignment while maintaining contact pressure against the shaft to preserve the fluid barrier.

What installation considerations ensure effective performance?

Correct interference between bore and housing, careful alignment of the shaft, and avoiding damage to the sealing lip during fitting are essential for optimal operation.

How does the seal behave under rotary motion?

The geometry is intended for dynamic service where the sealing lip maintains a sliding contact to control leakage and prevent ingress of particulates.
