FC keyless locking bushes

FC keyless locking bushes are thin-walled bushes that allow you to set the pulley in any position on the shaft and only then clamp it. The small wall thickness means they fit in small pulleys and hubs.

FC keyless locking bushes - several shaft diameters in one hub

In the FC type, several shaft diameters share the same outer bush diameter. You can therefore use one hub with shafts of slightly different diameters, replacing only the bush. You save space, keyway machining and assembly time.
