The duty cycle describes the ratio of operating time to idle time and is specified as a percentage. At a duty cycle of 20%, a screw jack operates for 12 minutes within one hour and remains idle for 48 minutes.

Which factors influence the duty cycle?

The influencing factors are:

  • high loads on the screw jack
  • high speeds
  • the choice of screw type

High loads mean high friction. High friction is associated with high heat generation and influences the duty cycle. High speeds have a similar effect. The higher the screw jack speed, the higher the friction and heat generation.

What role does the screw type play?

The choice of screw type also influences the duty cycle. This includes the selection between:

  • ball screw
  • trapezoidal screw
