ActionJac™ Worm Gear Screw Jack systems are ruggedly designed and produced in standard models with load handling capacities from 1/4 ton to 100 tons. Metric capacities are also available from 5 kN to 200 kN.

Joyce worm gear machine screw jacks lift and precisely position loads (250 pounds to 250 tons). Upright or inverted jacks operate at full capacity in tension or compression. WJ and RWJ, single lead jacks are self-locking. DWJ and DRWJ, double lead jacks offer increased travel speed and require a brake or external locking device to hold position.

Worm Gear Screw Jack systems are ruggedly designed and produced in standard models with load handling capacities from 1/4 ton to 100 tons with no "standard" tra

Screw Jacks are mechanical transmission devices used to convert rotational motion into linear motion for wide range of industrial applications. They incorporate a worm gearbox mechanism where an alloy steel worm rotates a high strength bronze worm gear. Rotation of worm gear causes a linear motion of lifting screw or traveling nut on the screw.

The Inch and Metric Worm Gear Machine Screw Jacks incorporate an alloy or stainless steel worm which drives a high strength bronze worm gear (drive sleeve). The worm shaft is supported on anti-friction tapered roller bearings with external seals provided to prevent loss of lubrication.

Joyce/Dayton offers many different types of worm gear screw jacks, which are highly efficient and can precisely lift and position loads. The ball screw worm gear jacks can operate inverted or upright and in compression or tension at full capacity.

LiftingMotion motorized worm gear screw jack is driven by an electric motor to lift, lower, push or pull the object. The motor can be AC motor, DC motor, stepper motor, or servo motor. Load from 0.25T to 120T, the larger load can be custom made. Can be built into many types of …

2023年5月5日 · Worm Gear Screw Jacks Superior flexibility and strength for your linear motion applications Ruggedly designed with load capabilities up to 100 tons, Thomson screw jacks are built to specification to meet your application requirements.

Worm gear screw jack with rotating ball screw spindle provides advantages in relation to efficiency, speed, precision and running time. By using a standard worm gear screw jack with ball screw spindle, you can achieve linear speeds of up to 20,000 mm/min.

Screw jacks (also known as Worm Gear Screw Jack or Machine Screw Jack) consist of a gearbox (worm or bevel gearbox) and a screw (trapezoidal screw, ball screw), which converts a rotary motion into a linear motion with the support of a motor.
