Is the conveyor an end drive or a centre drive? Centre drives usually have pinch rollers and therefore the top and bottom surfaces of the belt will make contact with the rollers, unlike with an end drive. What if you want a flighted belt? Not possible with a centre drive for this very reason.
Will the belt get wet or be cleaned frequently? If you are changing the function of the conveyor to say a food environment, then the likeliness is that the conveyor will be frequently washed. If so, then the bearings may well need to be upgraded and some if not all parts be replaced with stainless steel or plastic components.
What kind of belt tracking does the conveyor have? Some bet conveyors have “Crowned rollers” that are a slightly larger diameter in the middle of the roller. This is used to align the belt. Some other conveyors use welded on flights or cleats on the underside of the belt that uses grooves in the bed and the rollers to align the belt.
