Electric Cylinders and Actuators
About Electric Cylinders and Actuators
Joyce Electric Cylinder Actuators lift and precisely position up to 20 tons, achieve travel speeds up to 546 inches per minute, and raise loads up to 100 inches. Requiring only electric power, Joyce Electric Actuators are well suited for industrial environments where protection of the lifting screw mechanism and dependable operation are critical.
- Low Maintenance actuator solution.
- Designed to operate at charted capacities in tension and compression.
- Parallel Motor mounts with additional gear reduction help you achieve target speeds.
- Direct Motor mounts increase travel speeds for faster output.
- Choose catalog models or customize to meet your requirements.
- Replace hydraulic actuators with this clean alternative.
- A quieter solution than pneumatic actuators.
How to Size an Electric Cylinder Actuator
Electric Cylinders are sized based on their static thrust capacity, but selection of the best model and configuration of electric cylinder for specific applications requires further consideration.
Joyce’s complementary JAX® Online software makes it easy to size a single unit of a complete system. Contact one of our Application Engineers today.
-
First consider the mounting orientation and static load. Vertical mounting and operation permit a longer maximum rise (stroke) than horizontal mounting and operation of electric cylinders. For a given thrust capacity, maximum rise values may differ based on the screw type and diameter. Be sure to check Quick Reference pages.
-
Consider the DYNAMIC load. The speed at which the load will be moved is a limiting factor. Quick reference pages for are arranged from slowest to fastest operation of acme screw (ECA) cylinders and then ballscrew (ECB) cylinders. Scan down the list to the travel speed you need and then check the horsepower requirements to for the load you will be moving.
-
How frequently will the Electric Cylinder need to move the load? Electric Cylinders with Acme screws (ECA) have a calculated allowable continuous travel that limits duty cycle. Use JAX® to determine this value.
-
How long will the Electric Cylinder be in service? Electric Cylinders with ballscrews (ECB) have a calculated ball nut life, expressed in inches of travel, which can be used to estimate the life of the unit. Use JAX® to determine this value.

Joyce/Dayton offers motor controlsranging from simpleMotor Startersto complexpositioning systemsandCustom 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.

Available Models
Items to consider when selecting motors and mounting configurations:
Use Quick Reference Charts determine the motor horsepower and gear reduction required to reach your target speed. For example, slow travel of just a few inches per minute will require a high ratio electric cylinder paired with a 10:1 ratio external gear reducer. While fast travel up to 546 inches per minute will require a low ratio electric cylinder paired with a direct drive motor.
- Standard model Electric Cylinders are purchased without a motor or external gear reducer.
- Direct Drive models have the motor mounted directly to the input shaft of the Electric Cylinder. The motor extends at a 90 degree angle from eh electric cylinder.
- ComDRIVE models have mounted external gear reducers and motors. The combination of internal and external gear reduction is specified and it accounts for output speed of the specific electric cylinder.
NOTE: Brake motors must be specified for all ballscrews Electric Cylinders (ECB).and for any acme Screw Electric Cylinder (ECA) with an efficiency ratio greater than or equal to 30%.

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.
