premo® TP Line rotary servo actuators

  • premo® TP Line solves its challenge thanks to the exceptional precision and power density.

  • Less prone to fouling due to smooth surfaces and conical cover without screws.

The dynamic class

  • Perfect for challenging positioning and processing tasks
  • Minimal backlash and maximum torsional rigidity allow for the shortest cycle times and excellent surface finish
  • Mechanical interface with output flange
  • Ideal for connecting lever arms or pinions
  • Electric interface with HIPERFACE® singleturn absolute encoder for high positioning accuracy as standard
  • Optionally extendable with all available encoders and connector versions
