A trapezoidal thread has the shape of an isosceles trapezoid and has a flank angle of 30 degrees according to the ISO standard. The threads are often thicker than those of triangular threads. The task of a trapezoidal thread is to transmit movements and forces. A trapezoidal thread is also intended to convert rotary movements into linear movements. It is therefore often used in straight-line drives.
Since trapezoidal thread spindles are mainly in motion and have a lot of friction, the self-locking effect created by the pitch is an advantage. To ensure durability, the spindles are usually made of steel and the nuts are made of gunmetal, brass or bronze.
The possible uses of the trapezoidal thread spindle are very diverse. It can be used for machine tools, as a lifting spindle in presses, in handling equipment and in assembly lines. The trapezoidal thread spindle is also used for the adjustment movement in lifting systems and forklifts.
We manufacture trapezoidal threads or trapezoidal thread spindles with a diameter of 30 mm to 100 mm. The largest thread length is a maximum of 2600 mm when twisted and 500 mm when ground. A pitch is possible on both the right and left. Customer-specific special designs are also possible.
