Trapezoidal thread spindles are mainly used as drive or movement spindles. Trapezoidal lead screw are mainly used as drive or movement spindles. The flank angle is 30 degrees.
Trapezoidal lead screw 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 multi-start threaded spindles in various diameters and pitches. The threaded spindles also differ in terms of their direction of rotation, accuracy, material, length, and possible journal machining.
