The advantages of a leadscrew are: Large load carrying capability. All you need is a skate tool, some measuring tape, and your current wheels. *Depends on the manufacturer. Simple to design. Advantages include compact size, high efficiency, low backlash, and a high torque-toweight ratio; disadvantages are a complex and costly design. A smooth wheeled roller has a large steel drum in the front, drums in the back, and one or two wheels. They have two brake arms which mount to studs on the frame and fork. Not feasible where product accumulation is desired. The upper boot tends to come off from the frame. Less frequent replacement of wheels.
