Comparing Machine Screw Jacks and Ball Screw Jacks for Heavy Lifting Capabilities

When motion system designers want the application flexibility of an electric linear actuator and a hydraulic cylinder's heavy lifting, lowering and tilting capability, they often turn to screw jacks. Where electric actuators might handle up to two tons, screw jacks can handle more than 100. Their high load capacities come from a worm gear configuration that converts energy from motor or manual input. The two main types of screw jacks are machine screw jacks and ball screw jacks.

However, set screws can damage shafts and tend to loosen and slip during clutching and braking. Mechanical shrink fit providing uniform surface contact ensures no relative movement or loss of torque capacity over extended periods, reducing machine downtime and maintenance costs. Using the Concentric Maxi Torque keyless bushing connection system, components maintain their axial and radial position, reduce run out and increase machine efficiency. Reduced inertia results in increased power savings.
