FAQ

What is the difference between a cassette seal and a standard oil seal?

A cassette seal uses a multi element sealing system providing significantly higher contamination resistance and longer operating life.

How do I select the correct shaft seal?

The seal should match shaft diameter, housing diameter, width, operating conditions and lubricant compatibility.

Why is NBR widely used in industrial shaft seals?

NBR provides good resistance to oils, greases and fuels while maintaining stable sealing properties and wear resistance.

Is this seal suitable for rotating shaft applications?

Yes. The cassette design is specifically engineered for rotary shaft sealing systems and industrial drive assemblies.

Where are cassette shaft seals commonly used?

They are widely used in wheel hubs, axle systems, industrial gearboxes, agricultural machinery and heavy duty industrial equipment.
