ComDRIVEs are available in both "machine screw" and "ball screw". Both types combine a jack, motor and gear reducer into a single compact unit. ComDRIVEs are available in 2-ton through 30-ton capacities. ComDRIVEs can power an entire jacking system, reduce the number of components that must be specified, and simplify designs.
Alternate terminology: Machine Screw ComDRIVEs, Ball Screw ComDRIVEs.
