Trapezoidal-thread spindles and nuts
Trapezoidal-thread spindles usually have an effciency of less than 50 %. They are therefore only suitable for converting a rotary motion into a longitudinal motion. Our standard spindles mated with our standard nuts are therefore generally self-locking unless there are vibrations etc. The precision-rolled design with optimized lead and concentricity accuracy and wear-resistant surface which we have chosen for our stock programm is intended for the general mechanical engineering sector. This design as well as the tolerances chosen make the fnished product a favourably priced solution. The range of application of our trapezoidal-thread spindles is furthermore considerably enlarged as it is possible to choose among nuts of red brass, grey cast iron and steel; steel nuts, however, are not intended for motion screws. Trapezoidal-thread spindles of stainless steel are suitable for even more applications e.g. in the food industry. When used as motion screws, it is important to ensure adequate lubrication.
