    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)

    JWB Series Ball Screw Worm Gear Screw Jack
    Rotating Ball Screw Jacks use a ball screw and nut made from hardened alloy steel with bearing balls carrying the load between nut & screw. They 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. The ball worm screw jacks are suitable for high services as well as for a very rapid, quick and precise positioning. They can be driven by different motors: electrical, with either alternating or direct current, as well as hydraulic or pneumatic motors. Also they can be driven manually or with any other kinds of transmission. LUDE Transmission ball 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.

    JWB series high-efficiency worm gear ball screw jack
    JWB series high-efficiency worm gear ball screw jack
    JWB type (ordinary ball screw type) is suitable for high-speed, high-frequency and high-performance devices. The main components are precision ball screw pair and high-precision worm gear pair. The use of rolling friction improves the efficiency of the whole machine, and only a small driving source is needed to generate a large driving force. Compared with the trapezoidal screw, the speed is greatly improved, and it can run easily and at high speed. The use of high-quality ball screws increases its working life by more than 3 times. It has no self-locking function, it is necessary to add a brake device or select a drive source with brake.

    Ball Screw Jacks Low-friction ball bearings allow these screw jacks to use half the power required by an Acme screw jack to lift the same load. Typically used as actuators, they run at higher speeds than Acme screw jacks. They come assembled, threaded, and ready for hookup. Connect a motor or hand-crank shaft to the screw jack shaft to lift, hold, position, and level loads. Travel distance per turn, also known as screw lead, is the distance a load moves with one revolution of the shaft.

    Ball screw jacks feature a ball nut with integral ball bearings that circulate along the surface of the ball screw. This significantly reduces friction between the ball nut and the ball screw, resulting in greater efficiency. Ball screw jacks require up to two-thirds less input torque to move the load than similarly rated machine screw jacks. They require a brake motor or external locking device to hold position.
