FAQ

What are the required mating components for a complete H308 mounting assembly?

For a complete assembly, you typically need the H308 adapter sleeve, a corresponding KM8 lock nut, and an MB8 lock washer. These components are usually sold separately.

The correct procedure involves tightening the lock nut until the bearing's internal radial clearance is reduced by a specific amount. This should be measured with a feeler gauge. Refer to the bearing manufacturer's handbook for the exact clearance reduction values for your specific bearing type to avoid preloading and premature failure.

No, they are not interchangeable. While both are for a 35mm shaft, the '3' and '2' in the model number denote different dimensional series designed to match different series of bearings (e.g., H3xx for 222xx K series, H2xx for 22xx K series). They have different outer diameters and tapers and are not compatible.
