Roller Body: (1) The roller pipe adopts automatic cutting machine, with no deformation or chips when cutting the pipe body; The perpendicularity between the fracture and the pipe is high, and the parallelism between the two ends is high; (2) The roller pipe adopts special boring machine, which can simultaneously bore both ends of the roller pipe where bearings are installed, with high coaxiality; complete the end face flatting and interior angle cutting in one go; (3) Patented Technology of A Reducing Diameter Process: completely eliminates wear on the conveyor belt, greatly imporves the coaxiality of the idler, and effectively reduces the jumping and rotating resistance of the excircle. 4) Anti-rust Painting on the inner wall of the supporting roller: ensure good corrosion resistance. 2. Roller Shaft Use a slot flat double end milling machine to synchronously process the slot flat at both ends, ensuring that the slot flat of the roller shaft is symmetrical. 3. Bearing: 1) domestic and foreign first-class bran
