Metric and Imperial Ball Screw Jacks designs in translating and rotating screw formats in upright or inverted types are available in capacities up to 500kN ( 50 Ton). 2 gear ratios and 2 screw leads as standard, Options include Pre-loaded ball nut, Anti-rotation (keyed), 6 mounting options including trunnion and double clevis.
The Metric Ball Screw jacks have the extra advantage of an integral safety device as standard.
|
|
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

Series-S high duty screw jacks are a range of metric cubic screw jacks designed to have a higher duty cycle and mounting flexibility over conventional worm gear screw jacks. Typically the duty cycle can be extended by 50%. The higher duty rating has been achieved by improving the design of the jacks worm gearbox. The screw jacks are available in capacities from 25kN to 200kN in both translating and rotating screw configurations.

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.

Joyce/Dayton - Established 1873
Versatile Joyce Machine Screw Jacks lift and precisely position all kinds of loads from 250 lbs. to 250 tons. Upright or inverted, these precision jacks operate at full capacity whether the load is in tension or compression. WJ series single lead jacks are self locking under full lifting capacity, while DWJ double lead series jacks offer increased travel speed. Heat treated alloy steel worm shafts, aluminum/bronze worm gears and tapered roller or ball bearings provide rugged reliability.
Double extended worm shafts are standard. Joyce screw jacks come in translating screw, rotating screw (keyed for traveling nut) and keyed designs. All screw jack designs can be fitted with a protective boot. Jacks are available with one of four standard screw ends or special ends to meet your requirements.
An optional anti-backlash feature compensates for thread wear, assuring minimum play between lifting screw and worm gear for smooth, precise operation. Jacks equipped with the antibacklash feature are rated at full capacity under static conditions. For jack capacity under dynamic conditions please contact Joyce/Dayton.
Joyce/Dayton will custom design jacks to meet special requirements.
