HD series helical gear reducer 90 degree gearbox

Stainless steel screw jack SWL stainless steel screw jacks are specifically designed for positioning and lifting applications that are located in wet, corrosive and harsh environments. Metallurgical properties of stainless steel allow it to remain ductile even atvery low temperatures.All exposed surfaces and components feature stainless steel or bronze construction Nitrile rubber seals protect all internal mechanisms.

Lead screw jack is worm gear screw jack with (acme)lead screw .

An integrated compact combination of ordinary tooth screw/ball screw/planetary ball screw, reducer and motor.

1.Screw jack capacities from 1/4 ton to 350 tons 2.Available in machine screw, ball screw, stainless steel machine screw actuators, micro-miniature actuators, high duty cycle actuators, motorized machine screw and ball screw actuators, electric cylinders and motor control systems   3.Accessories include miter gear boxes, motor adapters, transducers, couplings, ball screws and ball screw systems, and locking rings 4.Can be used as alternatives to hydraulic and pneumatic systems

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.  

This linear servo actuator is available with ball screws , in different sizes and stroke lengths to fit a wide range of applications .

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.

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