Cubic Ball Screw Jack Supplier
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)

smalll screw jacks in high lead ball screw jack
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.

Hand Crank Table Lift Screw Jack Mechanism
The Crank Handle Screw Jack are ideal solutions for applications where electricity or power generators is inconvenient or dangerous, light weight, low duty cycle, low target cost and short travel length. The working principle of the hand operated worm gear screw jack is that the worm (also called the input shaft) is manually rotated by the hand wheel, the worm wheel is rotated by the worm, and the trapezoidal lifting screw is moved by the rotating worm wheel. The linear motion speed of the worm wheel manual screw jack trapezoidal lifting screw depends on the thread size and the worm gear speed ratio. Hand Operated Screw Jack is composed of hand wheel or hand crank and a worm gear screw jack.It is ideal solutions for applications where electricity or power generators is inconvenient or dangerous.
