FAQ

What does the B designation mean?

The B designation indicates a 40-degree contact angle, providing increased axial load capacity.

What is the difference between an angular contact bearing and a deep groove ball bearing?

Angular contact bearings are specifically designed to support combined radial and significant axial loads, while deep groove ball bearings primarily support radial loads.

Can the 7203 B MGK bearing be used in machine tool spindles?

Yes, it is commonly used in machine tools and spindle applications requiring precision and rigidity.

Is this bearing sealed?

No, the standard 7203 B MGK is an open bearing and requires lubrication according to the application.

Can angular contact bearings be mounted in pairs?

Yes, they are frequently mounted in matched pairs to support axial loads in both directions and increase system rigidity.
