Bevel Gear Screw Jack

Bevel Gear Machine Rotating Screw Jack offer higher efficiency and greater speed than other mechanical screw jacks

Bevel gear jacks use the same trapezoidal or acme screws used in machined screw jacks to move the load.

Lude’s Bevel Gear Jack, G Series, combines a Cubic Spiral Bevel Gearbox and Screw Jack resulting in a high speed, very accurate solution for lifting-lowering-pushing-pulling applications.

SWL Stainless Steel Hand Crank Screw Actuator is a basic lifting component. It has many characteristics, such as compact structure, small size, light weight, wide power source, no noise, convenient installation, flexible use, multiple functions, various supporting forms, high reliability and long service life. It can be used alone or in combination. It can accurately control and adjust the height of lifting or propulsion according to a certain program. It can be driven directly by motor or other power or manually. It has different structure type and assembly type, and lifting height can be customized according to user's requirements.  

The cubic compact screw jacks offer versatile mounting options and can be mounted upright or inverted to suit specific requirements.

Small acme Screw jack has compact structure and is a basis jackup part, accomplish the functions such as lifting, drop, push and inverting through  worm gear drives screw.

The cubic screw jacks offer versatile mounting options and can be mounted upright or inverted to suit specific requirements.

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)
