General product features

The trapezoidal thread is robust and moderately priced. It is the right choice for most adjustment tasks.

Spindle and nut are exposed to friction and must be well lubricated. Usually it is suitable for applications up to max. 20% of duty cycle. Most single-start trapezoidal threads are self-locking (that means the load is held at engine stop, which is particularly useful in suspended loads or applications where loads are being lifted).

Trapezoidal threaded spindles are also available in stainless material on request. ZIMM offers a wide selection of different nuts which have different advantages. Another aspect is the safety nut systems (SIFA) which are only available in trapezoidal thread design. There is no calculation for the life span of the trapezoidal thread drives as there is for the ball screw drives.
