A Screw Jack (also known as a Jack Screw, a Worm Screw Jack, a Machine Screw Jack ) is a devise used to convert rotational motion into linear motion. Machine Screw jack/lift is a basis jack-up part, accomplish the functions such as lifting, drop, push and inverting through worm gear drives screw.

An electric linear actuator is used primarily where an intermittent axial movement and positioning is needed. It is a good alternative to hydraulic and pneumatic cylinders due to the simple connection to electrical operational systems and the hygiene benefits. Electric Linear actuators  we offer is based on a worm gear drive. Such actuator is simple and of a sturdy construction. It is based on our worm gearboxes on which a set of cylindrical aluminum tubes and an inner threaded spindle are mounted.

We offer three types of bevel gear box, HD series,T series and ARA series, and they can be selected according to intended use and load torque.

The slewing drive is a gearbox that can safely hold radial and axial loads, as well as transmit a torque for rotating. The rotation can be in a single axis, or in dual axis together. Lude slewing drive can be driven by hand or by motors,like hydraulic motor,AC motor and DC motor. Slewing drive system are made by manufacturing gearing, bearings, seals, housing, motor and other auxiliary components and assembling them into a finished gearbox. It is easy to install, easy to maintain, and saves installation space to a greater extent. Customers can choose different drive source according to detailed need.
