When the cantilever roller is under stress for a long time and the stress on the cantilever roller is uneven, the cantilever roller may tilt or be damaged. The tilted cantilever roller cannot rotate around the axis and needs to be replaced. However, replacing the cantilever roller requires removing the cantilever roller from the conveyor belt system, which is cumbersome when disassembling the conveyor belt system.
