Unpowered roller

The roller is a cylindrical part, divided into driving and driven rollers. It is widely used in various transmission and conveying systems such as rotary screen printing machines, digital printers, conveying equipment, papermaking and packaging machinery. It is usually made of seamless steel pipes, and depending on the process, such as aluminum alloy 6061T5, 304L/316L stainless steel, 2205 duplex stainless steel, steel castings, and solid forged alloy steel cores are used as materials.

The production of the roller is mainly composed of the initial rolling of the roller body, the preliminary static balance of the roll, the interference assembly and welding of the shaft head, the fine turning and the fine tuning of the dynamic balance. If the behavioral tolerances such as roundness, cylindricity and straightness are required to be less than 0.2mm, it is necessary to use a cylindrical grinder or a roll grinder for grinding after finishing. If the surface hardness is required, it is necessary to increase the heat treatment process. (News recommendation: Size parameters and classification of unpowered rollers)
