Electric Cylinders

Joyce electric cylinders lift and precisely position up to 20 tons, achieve travel speeds up to 546 inches per minute, and raise loads up to100 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 to 20 ton thrust capacities available
  • 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
  • Custom finishes available

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.Parts list and illustrations are included in the O&M Manual. Serial numbers are attached to the product housing.

Electric Cylinders are available in Standard, Motor Mount, and ComDRIVE models.

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.

What you need to know to specify electric cylinders in industrial application.

Electric Cylinders are rated based on their static thrust capacity from 2.5-tons to 20-tons. But the selection of the best electric cylinder for the application requires further consideration.

  1. First consider the mounting orientation and static load. Vertical mounting and operation permits a longer maximum rise than horizontally mounted and operated electric cylinders. For a given thrust capacity, maximum rise values may also differ based on the specific screw type and lead. Be sure to check the chart at the bottom of the Quick Reference pages.
  2. Consider the travel speed of the DYNAMIC load. The speed at which the load will be moved is a limiting factor. Quick reference pages are arranged from slowest to fastest operation of acme screw (ECA) cylinders and then of ball screw (ECB) cylinders. Scan down the list to the speed you need then check horsepower requirements for the load you will be moving.
  3. 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 their duty cycle. Use JAX® jack selection software to determine this value based on the load and speed of travel.
  4. How long will the electric cylinder be in service? Electric cylinders with Ball screws (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® jack selection software to determine this value based on the load and speed of travel.

Specifying Motors, Brake Motors and gear reducers

Electric Cylinder Quick Reference Charts indicate travel speed as well as how that speed is achieved.

  1. Direct Drive – indicates that a motor is directly mounted to the Electric cylinder. We will provide the motor mount and motor based on the part number specified.
  2. External Gear reducers are indicated numerically by their ratio, 10:1, 7.5:1, and 5:1. Resulting travel speeds are based on the use of a 1750 RPM motor. We will provide the mounted gear reducer and motor based on the part number specified.
  3. Specify a brake motor for all ball screw electric cylinders (ECB) any machine screw electric cylinder (ECA) with an estimated efficiency ≥30%. Or if your application requires a brake motor. Joyce can provide the motor you need. Contact us with questions.

 

Take the work out of using electric cylinders in systems

Tell us what you need or use our exclusive JAX® Jack selection software (it’s free). We will put together complete systems with single or multiple screw jacks for you. The software is great because it calculates motor horsepower and shaft diameters and torques. Their are several common arrangements, but the program is flexible and allows you to design what you need.

Look for our next generation JAX® Online browser-based software soon. It includes the complete electric cylinder product line.

Where are Electric Cylinders used?

Electric cylinders are available as motorized units designed to meet specific travel distance and travel speed requirements. They offer a cleaner, quieter option to hydraulic and pneumatic cylinders. Available with either machine screws or ball screws, their enclosed screw offers added protection in wet and corrosive environments. They are commonly used in Industrial automation, mine door openers, valve adjustments, roller adjustments, engine lifts, and hoppers.
