Overview of 2-Stage Telescope Actuators
The 2-stage telescope actuator is a linear drive system, which offers the right solution for various application areas in mechanical engineering for large travels with limited spatial requirements.
The compact design elements of A.MANNESMANN offer small structural dimensions with the highest precision in performance.
High Flexibility in Application
The linear actuator is a functional unit that can be used to implement demanding drive and positioning tasks. These tasks include displacement movements of components with complex, path-dependent processes as well as pressing and joining tasks with direct force-path evaluation.
The compressed design opens up a variety of opportunities. The 2-stage telescope actuators achieve both precise travel movements in machine tool precision as well as the high power transmissions that are required in press and jig construction.
2-stage telescope actuators are used in a variety of ways in mechanical and plant engineering where more space is required, such as in aerospace, special machine construction or process engineering.

- Constant torque
- Very low power losses
- Uniformly low operating temperatures
- Can be used in all installation positions
- The highest power transmission rates
- Extremely high degree of efficiency (up to 98%)
The 2-stage telescope actuator is marked as follows:
- Telescopic ball screws
- Compact design
- High extension ratio
- High effective pitch
- Central torque introduction
- Driven spindle
- Driven nut
In the event of a space gain of up to 262%, A.MANNESMANN telescope actuators work with large axial load capacity with extreme precision. The patented 2-stage telescope actuators convert the central rotatory drive motion of the motor into an axial translation movement through a telescopic ball screw.
Telescopic ball screws consist of two nested precision ball screws. The resulting partial movements split according to the thread pitches and occur absolutely synchronously.
The highest precision positioning and repeat accuracies are achieved through backlash-free, preloaded double nuts and ball screw spindles with ground precision in the accuracy quality IT 3.
High long-term durability is formed by perfect machining at A.MANNESMANN with high quality materials and heat treatment with the highest hardness.
The torque and the very high degree of efficiency of the telescopic levels of more than 90% are constant across the entire travel. Only in this way do very low power losses and evenly low operating temperatures result.
