Festo Rotary Actuators – Semi-rotary Drive DRRS

Festo Rotary Actuators - Semi-rotary Drive DRRS

Technical Specifications – Semi-rotary Drive DRRS

Festo semi-rotary drives DRRS operate on the rack-and-pinion principle and are extremely accurate in the end positions. They offer high load-bearing capacity with precise and backlash-free bearings, high mass moments of inertia, defined interfaces, and are perfectly suited for handling applications.

Key Features

  • Rack-and-pinion principle
  • Extremely accurate in the end positions
  • High load-bearing capacity for the bearing, precise and backlash-free
  • High mass moments of inertia
  • Defined interfaces
  • Compressed air connection on both sides for the larger models
  • Slots on both sides for mounting proximity switches
  • Choice of mounting options
  • Perfectly suited for handling applications
