Roller conveyor

摘要

Roller conveyor having load-driving shafts which are arranged between extruded profiled rails and an outside main drive shaft, each profiled rail having, to simplify production, a drawn guiding groove on its exterior on both sides of passage bores for the load-driving shafts in each case and bearing supports being inserted into the said guiding grooves, which supports hold bearings for the load-driving shafts, so that the passage bores can have a diameter which is markedly larger than that of the load-driving shafts.
