Non-Weding Structure:Changing the way how bearing housing and roller tube connect:Instead of welding, we make the bearing housing bigger, let it be the edge of roller tube, and then connect the steel tube at a 180° angle. The non-welding structure free us from many problems caused by welding, like:Poor Concentricity; the bearing housing and roller tube are easy to separate from the welded Self-Training Return Idler Davis IndustrialApplications. Used to correct belt misalignment on the return side. Return trainers are available for one-way or reversible belts. Normal spacing is 100 to 150 feet apart. At least one return trainer should be used on conveyor lengths of 100 feet or less.
