These Joyce electric cylinders lift and position up to 2.5 tons, achieve travel speeds up to 291 inches per minute, and raise loads up to 44 inches. They are well suited for industrial environments where protection of the lifting screw mechanism is critical and low maintenance is desired. Requiring only electric power, Joyce electric cylinders may also be used in place of hydraulic cylinders, eliminating the cost and potential for leaks associated with hydraulic systems.

  • 2.5 ton capacity and available in a variety of ratios and leads
  • Standard, Motor mount, and ComDRIVE models are available
  • Ground and hard-chrome plated inner tubes, alloy steel input shafts
  • All models with efficiencies ≥ 30% require a brake motor to hold position
  • Joyce Dayton can customize electric cylinders to your specifications

Complete dynamic speed/load ratings and maximum rise information can be viewed on our quick reference charts. Both acme (ECA) and ball screw (ECB) electric cylinder actuator models are designed to operate at the charted capacities under both tension and compression loading.

Motor Controls:

Joyce/Dayton offers motor controls ranging from simple Motor Starters to complex positioning systems and Custom controls. Every system that is powered by an electric motor requires a control system. At Joyce, we know that choosing the best option can sometimes be a challenge. That’s why our Engineers are available to help you through the process.

Important Note: Electric cylinders that are ≥ 30% are not self-locking. Brake motors or external locking systems are required.
*W: Load in pounds.
Tare Torque: Initial torque to overcome seal and normal assembly drag. This value must be added to starting torque or operating torque values.
Starting Torque: Torque value required to start moving a given load (dissipates to operating torque values once the load begins moving).
Operating Torque: Torque required to continuously raise a given load at the input RPM listed. 
Translating Tube Torque: Torque required to resist tube rotation.
Lead: The distance traveled axially in one rotation of the lifting screw.
Pitch: The distance from a point on a screw thread to a corresponding point on the next thread, measured axially.
