FAQ

Question?
What are the required lock nut and lock washer for the FAG H3030 adapter sleeve?

The H3030 adapter sleeve is designed to be used with a KM 30 lock nut and an MB 30 lock washer. These components are necessary to securely fasten the bearing onto the sleeve and the sleeve onto the shaft.

Mounting should be done by either measuring the clearance reduction or by measuring the locknut tightening angle. The most reliable method is measuring the reduction in radial internal clearance using a feeler gauge. This ensures the correct interference fit is achieved without overloading the bearing. Refer to the FAG mounting instructions for detailed values.

Yes, the H3030 is a standard precision component suitable for a wide range of applications, including those with high rotational speeds. However, proper balancing of the entire shaft assembly, correct lubrication, and achieving the right operational clearance are critical for optimal performance and longevity at high speeds.
