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 Manufacturer of screw jacks have the extra advantage of an integral safety system as standard.
Stainless Steel execution available.
Capacities from 1 Ton to 30 Ton.
Stroke on request.
Body with Base or Pivoting feature.
Upright or Inverted Screw.
Translating or Rotating Screw.
Motor applications.
Joyce Ball screw jacks feature a ball nut with integral ball bearings that recirculate along the surface of the manufacturer of 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 manufacturers, professional encoders, geared potentiometers, direct drive and reducer mounts, and protective professional 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 braking motor or other external braking mechanism is required.
