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)
