Linear Positioners

Free Application Review

[Specifications For Series 20A, 40A, 45, and 50]

Comptrol linear positioners combine the mechanical load carrying capacity and positioning accuracy of a ballscrew with the power of programmable motion control capabilities of today's motor, drive and control technology. The result... a motion control package that delivers the positioning accuracy and flexibility needed for:

  • Repetitive, bi-directional linear motion
  • Single or multiple positioning moves per cycle
  • Smooth, precise position control
  • Simple or complex velocity profiles
  • Controlled acceleration and deceleration
  • Load variations
  • Quick job changeover

and a cost-effective alternative for other linear actuator systems which require costly mechanical stops, switches, pumps, cams and reservoirs.

Choose the right combination for your application ^

  • In-line or motor parallel configurations
  • Dynamic load capacities up to 12,900 lbs.
  • Thrust capacities up to 14,800 lbs.
  • Stroke lengths up to 49"
  • Speeds up to 60" per second
  • Any servo or stepper based drive systems
  • Base, foot, front, or clevis mount
  • Home and Over travel Sensor Kit
  • Brake and/or encoder


Rugged Design for superior thermal stability, stiffness, and alignment ^

  • Thick-walled one-piece extruded aluminum body prevents twisting and bending of the unit under load.
  • Bearing and bushing bores are machined into the heavy cross sectional area making these components an integral part of the structure.
  • Dual supports rods reduce the effects of side and overhung loads on ballscrew performance and efficiency. Wide spacing between the rods provides additional torsional stability and support for cantilever loads.

Typical applications involve: ^

  • Material handling
  • Part locating/ejecting
  • Cutting or slitting
  • Programmable stops
  • Incline adjustment
  • Automated assembly
  • Applicators/Dispensers
  • Tool or probe positioning
  • Pick and place
  • Part transfer
  • Robotics
  • Staging
  • Diverters or gates
  • Lifting / height adjustment

Precise, long-lasting positioning accuracy ^

  • Standard high efficiency ballscrew and nut assemblies assure reliable positioning accuracy. Precision ground, preloaded, and higher lead screws are available.
  • All accuracy producing components are protected from dirt and contamination inside the positioners one-piece extruded body.
  • All units feature Comptrol's exclusive lubrication delivery system to the ballnut. The external ports on the load mounting plate accept standard fittings for manually lubricating the system or for connecting to an automatic lubrication system.
  • Optional encoder and/or brake combinations for accurate position feedback and maintaining position.
  • Optional Home/Over travel Sensor Kit includes three proximity sensors which can be wired for NO or NC and sink (NPN) or source (PNP) outputs.

The right combination of speed, power, and torque ^

  • Motor mounting plate adapts easily to any manufacturer's motor.
    In-line motors couple directly to the ballscrew.
  • Parallel motor configurations utilize the latest timing belt technology and offer optional pulley ratios for maximum performance.
  • Gear box arrangements, special motor configurations, or positioners without motors are available.

Easy to install and setup ^

  • Delivered as a complete self-contained easy to install unit.
  • T-slots in the top and bottom of the base for adjustment of sensors and mounting hardware.
  • Load plate mounting holes are counterbored and tapped for threading into or bolting through the plate for attaching the load.
  • Configured for base, foot, clevis, or front flange mounting.
