Roller Application: roller against the frictional force between the roller and the tape rolling supply conveyor roller, so as to achieve the purpose of the work. Roller has good waterproof and dustproof performance, small resistance to rotation of conveyor idler price, and running balance conveyor idler processing, long life and other characteristics. Roller axial movement: the conveyor roller at 500N axial load, axial movement of the roller is not greater than 1.2mm. Roller installation: roller assembled commissioning should always check rotation is flexible and immediate adjustment. On-site installation of roller bracket portion to be installed in the conveyor.
