Joyce/Dayton - Established 1873
Joyce Ball Screw Jacks feature a ball nut with integral ball bearings that recirculate along the surface of the ball screw. The significantly reduced friction between the ball nut and screw results in greater efficiency, with up to 2/3 less input torque required to move the load than a similarly rated machine screw jack.
Compared to Machine Screw Jacks, Joyce Ball Screw Jacks
- Require less motor horsepower
- Allow higher travel speed
- Provide an extended duty cycle
Joyce Ball Screw Jacks are available in translating screw or rotating screw (keyed for traveling nut) designs. Translating screws are available with threaded, load pad, clevis or plain ends. Options include limit switches, encoders, geared potentiometers, direct drive and reducer mounts, and protective boots. Joyce Ball Screw Jacks are ideal for single or multiple jack systems.
Unlike Machine Screw Jacks, Ball Screw Jacks are not self-locking. Because they will lower under load, a brake motor or other external braking mechanism is required.

Nook ActionJac Worm Gear Screw Jacks are mechanical actuators that utilize a bronze worm gear with a screw.
Nook offers a complete line of standard and custom engineered ball screw and machine screw actuators for applications from 1/4 ton up to 100 tons. Standard configurations including upright or inverted units with translating or rotating lifting screws. Top plate, threaded, or clevis ends are available for meeting specific application needs. Actuators can be used individually or in mutliple jack arrangements for a larger mechanical system.

These standard screw jacks use a ball screw shaft and are ideal for high-speed or high-frequency operation.
They are also environmentally-friendly; even when operated at high speeds, and generate little heat, little noise, and no oil leakage.
* Standard Capacity: 10~1000kN
* Rolling motion between the nut and screw is same as ball bearings.
3 times of high efficiency compare with standard screw jacks will provide save energy operation
* No self-lock function; braking mechanism is necessary when retaining the position
* An application to prevent the screw axis from rotating is available
* Bellows for screw axis protection, Trunnion Base, Limit Switch for control, RC Encoder, etc are also available
