FAQ

What is the correct procedure for mounting a bearing using this H309 sleeve?

The bearing should be pushed up the tapered sleeve until the required reduction in radial internal clearance is achieved. The final position is secured by tightening the corresponding lock nut (KM9) and bending a tab of the lock washer (MB9) into one of the nut’s slots.

Which lock nut and washer are required for the H309x40mm sleeve?

The standard compatible hardware for an H309 sleeve is a KM9 lock nut and an MB9 locking washer. These components are not included and must be sourced separately.

Can this sleeve be used with any type of bearing?

No, this adapter sleeve is specifically designed for use with bearings that have a tapered bore (taper 1:12), such as certain self-aligning ball bearings, spherical roller bearings, and CARB toroidal roller bearings. It is not suitable for bearings with a cylindrical bore.
