Screw jacks and accessories - example applications
The range of products offered by NEFF GEWINDETRIEBE is not limited to catalog solutions. Each project can be adapted to the individual needs of the customer, and often completely non-standard executions or unusual ways of using lifts and their accessories are introduced.

Lifting the platform in an industrial AGV vehicle
M-TEG series screw jacks without additional linear guidance, applied in the industrial AGV vehicle. The drives are synchronized by master-slave control. The screw jacks are equipped with a locking nut and can reach a lifting height of up to 700 mm with a mounting height of 300 mm.
Custom lifting drive for pressing processes.
The lifting drive consists of 4 KGS-6310 ball screws and 4 KGF-D-6310 ball nuts, 2 tension rollers and 5 gear wheels, which are connected by a timing belt. The lifting drive is driven by a motor with a cylindrical gearbox. The axle bearings take up tensile and compressive loads of the individual ball screws. The maximum pressing force on the ball nut is 76 kN, a total of 304 kN. The maximum press speed is 370 mm/s, and the maximum stroke is around 180 mm.
A scissor lift table with a trapezoidal screw for carrying heavy loads.
The TGS Tr14x4 trapezoidal screw in right-left (RH/LH) version, in this case with a knob, affects the scissor legs for adjusting the height of the platform.
3D printer with a trapezoidal screw for adjusting the height of the head.
The trapezoidal screw provides precise adjustment of the stroke. In this case, the TGS Tr10x3 trapezoidal screw and the ready-to-mount plastic trapezoidal collar nut TGM-EKM are used.
A scissor lift table.
Two N-type screw jacks connected by Cardan shafts, equipped with GA ends mounted directly on the threaded screw, realize the height adjustment in the scissor lifting arrangement. The kinematics of the jacks generate tension on the screws, so the permissible shear force does not have to be taken into account. The system is driven by 2 three-phase motors in master/slave mode.
Adjustment of the height of the unloading device.
The C-series screw lift mounted on the swivel base is responsible for adjusting the height of the unloading device attached to the swivel arm.
A linear gate robot.
The flexible modular screw jacks series M/J allows for optimal fitting of all sizes to the respective requirements. The 2 screw jacks for the X and Z axes of the linear gate robot solve a wide range of automation tasks. The portals can be flexibly mounted using standard interfaces.
Robot Gripper.
Trapezoidal screw drives can be found as structural elements of stable grippers in robotics. The TGS Tr10x2 trapezoidal screw driven by a stepper motor activates parallel manipulators for precise gripping.
Synchronous Telescopic Screw Drive for Medical Technology.
A two-stage, synchronously extending telescopic screw drive for electromechanical height adjustment of insulating blocks and operating tables. Available in trapezoidal or ball screw version.
Electric window drive for opening and closing hard-to-reach skylights and roof windows.
It consists of a KGS-1610 ball screw and KGM-1610 ball nut, which are powered by a direct current (DC) drive with an integrated limit switch.
Electric mesh cleaning machine
Mobile electric mesh cleaning machine is used to remove contaminants (branches, leaves, civilizational waste, etc.) in a storage power plant. The two C5 size screw lifts (vertical screw version on side E, vertical screw version on side F) used here drive the motors to perform the process of raising and lowering the inlet grate, as well as the mechanism of opening and closing the container for the cleaning agent.
Taking fuel cell production to a new level
4 reinforced screw jacks with ball screws are connected by rigid Cardan shafts to drive a specialized press for the production of bipolar plates. This process is one of the most innovative manufacturing technologies in terms of precision, minimal tolerance, component optimization, and production economy. Bipolar plates are a key component of polymer electrolyte membrane (PEM) fuel cells. The unique advantage is that all internal and external geometries relevant to the stack, as well as the flow field, can be produced simultaneously in an integrated process, providing maximum precision.
Paper Picker
In this system, two TGS Tr55x9 RH/LH trapezoidal screw jacks are connected to a high-performance MH5 screw jack. The screws are supported by special bearing assemblies. The drive is powered by a three-phase motor. Two integrated TGM-EFM trapezoidal thread nuts are used to implement the mechanism of two paper roll holders.
Car simulator
A car simulator with two linear actuators with a 24V BLDC motor and a planetary gearbox for adjusting the height and tilt of the driving simulator. A GT-2050 traction screw with a nominal diameter of 20 mm and a stroke of 50 mm was used. The 54-size actuators with a decentralized control unit can move with a force of up to 15,000 N and are supplied in IP54 protection class.
Automatic bar feeder.
Three M/J screw lifts are used to separate bars from the coil one by one and feed them into the feeder. To accommodate different bar diameters, three more screw lifts are responsible. The screw lifts are connected by RA universal joints. Each of the slow speed transmissions is driven by a diameter adjustment knob.
A manual locking system.
An additional locking system for manual screw jack drive. A specially prepared adapter for locking the drive shaft also enables the installation of a tachometer.
