Joyce Ball Screw ComDRIVEs combine a ball screw jack, motor and gear reducer into a single compact unit. Motorized ComDRIVEs are available in 2-ton through 30-ton capacities. Available in Translating, KFTN, and double clevis designs, they provide travel speeds up to 55.5 inches per minute. Ball screw ComDRIVES require up to two-thirds less input torque to move the load than a similarly sized machine screw jack ComDrive. They require a brake motor or external locking device to hold position.
Parts list and exploded views are included in the O&M Manual. Serial numbers are attached to the product housing.

Important Note: Ball Screw ComDRIVEs are not self-locking. Brake motors or external locking systems are required.
Joyce/Dayton provides 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.
Boots and special finishes are available for Joyce Ball Screw Jacks. Choose from a variety of boot materials and designs for the jacks you select(translating or KFTN). Joyce offers premium finishes, outdoor paint process, and custom finishes to meet your specifications. We have a hassle-free process for delivering what you need.
What you need to know to specify Motorized Ball Screw ComDRIVE jacks in industrial application.
Travel speeds and load capacities of standard ComDRIVE jacks are listed in the catalog. Here are a few tips.
Ball Screw Jacks are rated based on their static thrust capacity from 1-ton to 50-tons. But the selection of the best jack for the application requires further consideration.
Once loads, duty cycles, and travel speeds are established, designers must select which jack design to use.
Special features inherent in wormgear ball screw jacks.
Ball screw jacks include ball nuts that are about 90% efficient so the jacks require much less energy to lift an equal load than their machine screw jack counterpart. They are NOT self-locking so a brake motor needs to be included in the drive system and hand wheels are not a recommended option.
Take the work out of using screw jacks in systems
Tell us what you need or use our exclusive JAX® Online 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. There are several common arrangements, but the program is flexible and allows you to design what you need..
Where are worm gear ball screw jacks used?
Motorized worm gear ball screw jacks are fast and efficient. They can accurately position and hold loads up to 50-tons. Examples include: Platform lifts, Damper adjustments, Ergonomic lifts, Maintenance lifts, Roll adjustments, Earth Station Antennas, Solar Trackers, Conveyor adjustments, Packaging equipment, and Gate adjustments.
