Electric Cylinders by Joyce

Air-Oil Systems
Manufacturer: Joyce

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.

  1. 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.

  2. 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.

  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 duty cycle. Use JAX® to determine this value.

  4. 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.

  5. 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.
