Linear Actuators

ServoBelt™ RA Actuator

Actuation redefined.

Based on our proven ServoBelt™ Linear technology, the new ServoBelt™ RA actuator serves as a high-performance, drop-in replacement for applications that have traditionally used rod actuators, pneumatic cylinders or even linear motors.

  • Guided Operation. Unlike traditional rod actuators, ServoBelt RA is fully guided along the entirety of its stroke, making it more resistant to off-axis loads and more stable in on-axis moves.
  • High Performance, Low Cost. With linear forces up to 200 N, speeds up to 4 m/s, accuracy to +/- 4μm per meter and bi-directional repeatability as low as +/- 25μm depending on deceleration profile, ServoBelt RA performance compares favorably to linear motors that cost thousands more.
  • Moving Chassis. The ServoBelt RA has been built from the ground up for moving chassis installation in both horizontal and vertical Z-axis orientations. Its drive unit features standard or custom mounting hole patterns to make it easy to integrate ServoBelt RA into your machines.
  • Drop-in Replacement. A range of standard motor offerings enables the replacement of pneumatic cylinders simply by connecting DC power and rerouting servo-valve signals to the ServoBelt RA.
