(1)Cubic housing jack has the small size, compact and robust structure and mounting versatility.


(2)Cubic screw jacks boast an extensive performance range capable of both compressive and tensile loads。

(3)with a cubic housing shape unite the idea of converting a rotary movement into an axial movement with the aesthetic exterior of the cubic housing to form a functional unit, through which the constructive basic idea of a simple and robust Screw jacks design was ideally realised.


(4)Advantages

Minimisation of the necessary components and maximisation of the effectiveness of these components

Relatively large lifting and moving forces can be realised in the smallest of spaces

The spindle is guided through the housing

The cubic housing shape makes attachment to existing construction elements simple

    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)

    SJB Model Ball Screw Jack with Top Plate End
    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. The ball screw jacks are suitable for high services as well as for a very rapid, quick and precise positioning. Ball Screw Jacks use a ball screw and nut made from hardened alloy steel with bearing balls carrying the load between nut & screw. This rolling action reduces the friction between nut and screw, permitting smooth and efficient load movement that requires approximately 1/3 less torque than a machine screw jack with the same load. Ball screw jacks are preferred for:  Long travel lengths . Long, predictable life .  High duty cycles.  Oscillating motion

    SJA/SJB series SJA Control screw rotation Absolute mechanical synchronous lift system Safety nut design, monitoring the wear and tear of the product, eliminate hidden dangers And gear motor and all kinds of accessories module combination to meet customer requirements Load capacity range: 500 kg -100 tons Ball screw jack life calculation Ball screw jack SJB series life mainly depends on the life of the ball screw and worm gear and other components; we mainly check the life of the ball screw, the worm will wear, but life of the worm is generally longer than the ball screw. Life expectancy for ball screws L10 is the operating distance at which 90% of ball screws meet or exceed the fatigue life of metal materials. The unit is millions of millimeters. Ball screw life expectancy L10 is not a promise of durability, while life expectancy should need the correct maintenance, no pollutants and the correct lubrication. If the life expectancy of the ball screw needs to above 90%: then multiply the life expectancy by the following coefficients
