# Stroke frequency

In drive technology, the **stroke frequency** is the number of strokes in relation to the duration of the count. The numerator of this frequency shows the number of strokes as a dimensionless, mechanical variable, and the denominator shows the time required for this. In some cases, the stroke frequency is also expressed as the number of double strokes per period .

The desired stroke frequency is an important parameter for the design of a linear guide or a linear drive , as this has a considerable influence on the service life of linear technical applications. If the length of a stroke and the stroke frequency are known, the distance that is covered in a given time can be calculated.

Depending on the application, stroke frequencies of a few strokes per hour or day (example: bathtub lifter ) but also of a few hundred or thousand strokes per second or minute (example: high-frequency linear drives in medical technology laboratories) are possible.

Lifting frequency is also used for pumps , presses , lifting platforms and other technical applications.
