The ball screw jacks can be employed for lifting, pulling, moving, aligning any kind of load with a perfect synchronism, which is difficult to obtain by means of other handling devices.

5 KN  Small Screw Jacks, also called 5 kN Cubic worm gear screw jack or small worm screw jack.

SWL trapezoidal screw jack is suitable for low speed and low frequency. Lude Transmission trapezoidal screw jacks are designed and manufactured using innovative technology so to supply a product which identifies itself with the state of the art in the transmission devices.The screw jacks can be employed singularly or in groups properly connected with shafts, joints, and/or bevel gearboxes. Screw jack SWL series features: 1.Economical: compact design, easy operation, convenient maintenance. 2.Low speed and low frequency: Be suitable for heavy load, low speed, low service frequency. 3.Self-lock: Trapezoidal screw has self-lock function, it can hold up load without braking device when screw stops travelling .  

Trapezoidal Worm Gear Screws Jacks can provide long duty life, high load capacity and flexible design. They come in two major categories, Ball Screw and Machine Screw.

Screw jack lift system structures include miter gearboxes, screw jacks, electric motor or gear reducer, hand wheel, pillow block bearings, jaw couplings and line shafts.

Ball screw jacks combine the gear unit with a linear drive performed by a ball screw that, in comparison with the traditional acme screw, offers following advantages: • higher total efficiency • longer life of the whole linear drive system The following two comparative examples give an idea of the higher efficiency that can be obtained with this system: • considering a screw jack consisting of a worm gear with linear drive performed by an acme screw,  the total efficiency of the screw jack is between 10 % and 40 % • considering a screw jack consisting of a worm gear with linear drive performed by a ball screw, the  total efficiency of the screw jack is between 30 % and 70 % Our Ball screw jacks are available in two different models: • travelling screw (Model A,namely translating type) • travelling nut (Model B,namely rotating type)

The motor for screw jack can be servo motor,AC motor or DC motor. Its load capacity can be from 2.5ton to 120ton.
