FAQ

What bearing series is the H318 adapter sleeve compatible with?

The H318 is typically used with self-aligning ball bearings (series 12, 22), spherical roller bearings (series 222, 232), and CARB toroidal roller bearings with a tapered bore corresponding to a 90mm bore diameter.

What are the required accessories for mounting an H318 sleeve?

For a complete and secure installation, you will need a corresponding lock nut (model KM18) and a locking washer or clip (model MB18). These items are often included but should be verified.

What is the correct procedure for tightening the sleeve?

The correct fit is achieved by driving the bearing up the tapered sleeve, which reduces the bearing’s radial internal clearance. This is typically done by tightening the lock nut and measuring the clearance reduction with feeler gauges until the manufacturer’s recommended value is reached.
