Nuts with trapezoidal threads are mainly used as drive or movement spindles. With trapezoidal threads, the profile of the threads has the shape of an isosceles trapezoid. The flank angle is 30 degrees.
Trapezoidal threads are usually self-locking. Due to the geometry of the thread flanks, they can absorb higher forces than, for example, metric screw drives.
Compared to ball screws, the trapezoidal screw drive is significantly less efficient due to the sliding friction between the nut and the spindle. The ideal combination of spindle and nut material can significantly improve the coefficient of sliding friction and thus also the efficiency.
We supply both single and multiple thread nuts in various diameters and pitches. The nuts also differ in their direction of rotation, material, geometry and functionality. It is also possible to manufacture nuts using the injection molding process. The scope of delivery also includes safety nuts and preloaded nuts.
