Thanks to the processing of solid steel, this precision shaft is particularly robust and offers a high load-bearing capacity. The metal model has a diameter of 12 mm and is axed to the appropriate length before shipping. A deviation of one millimetre is possible. In addition, the model offers a low coefficient of friction against plastic plain bearings. This means that the bearings can be used longer and can be used more economically. The steel shaft is rounded off by a favourable purchase price.
