Screw Jacks
Screw jacks are an ideal electromechanical alternative to hydraulic or pneumatic systems. They provide precise control and inherent safety through self-locking gearboxes while significantly reducing energy consumption. Their robust design ensures a long service life and reliable operation, even under demanding industrial conditions.
They are available in various designs and performance classes to meet specific needs, including compact and flexible housings for easy integration, classic heavy-duty gearboxes for high loads, and high-performance and high-speed versions for short cycle times and fast lifting movements. Depending on the application, systems can be configured with different spindle concepts, such as basic or traveling nut versions, and can be complemented with options like motors, rotary encoders, and limit switches for automated operation. Explore our extensive product range, which includes cubic, classic, high-performance, and high-speed screw jacks, as well as spindle actuators, available in various configurations or as custom solutions.
Cubic Screw Jacks
MJ and BJ Series Cubic Screw Jacks are available in a total of 11 different types. Each of these types is available with both a basic and a traveling nut version. The load capacity varies depending on the type and can range from 2.5 kN to an impressive 500 kN.
The cubic housing design impresses with its flexibility for attaching useful components such as rotary encoders, motors, inductive gearbox switches, etc., and offers space for special solutions.
3 reasons why Cubic Screw Jacks are perfect for your project:
- Cost savings due to 70% less energy consumption compared to conventional hydraulic or pneumatic systems
- Standard gearboxes provide greater safety due to self-locking
- Low installation effort

The Classic Screw Jacks (MC) are available in a total of 14 different sizes. Each of these sizes are available in both a basic version (lifting spindle) and a traveling nut version (rotating spindle and running nut). The load capacity varies depending on the size and can range from 5 kN to an impressive 2,000 kN.
Here are three reasons why Classic Screw Jacks are a perfect fit for your project:
- Cost savings due to 70% less energy consumption compared to conventional hydraulic or pneumatic systems
- Standard gearboxes provide greater safety due to self-locking
- Low installation effort
High-Performance Screw Jacks
When short cycle times are important and large loads need to be moved quickly, High-Performance Screw Jacks are the solution.
With a total of 9 different versions, we offer you the optimal solution for your requirements. Our gearboxes start with a load capacity of 5 kN, depending on the size, and can handle impressive loads of up to 1,000 kN.
The gearbox housing, equipped with cooling fins and oil filling, ensures particularly good heat dissipation and thus enables a shorter cooling time or a longer usable operating time.
3 reasons why High-Performance Screw Jacks are the perfect fit for your project:
- Produce more in the same time compared to conventional hydraulic or pneumatic systems
- Fast load movement due to double input speed
- Shorter cycle times
Screw Jacks are available in basic and traveling nut version.
High-Speed Screw Jacks
High-Speed Screw Jacks achieve high speeds thanks to bevel gear transmissions while consuming minimal energy. They are specifically designed for fast lifting movements and allow for rapid and efficient adjustments, significantly reducing stroke times, while offering fast responsiveness and precision for quick adaptation to changing loads. This ensures effective adjustment and control, even with shifting requirements.
3 reasons why High-Speed Screw Jacks are perfect for your project:
- Enables short cycle time
- Low assembly and maintenance effort
- Low installation effort
Spindle Actuator
The new Spindle Actuator is a highly advanced electromechanical drive that is extremely eco-friendly and low-maintenance due to its fully sealed design. Additionally, it only requires a power cable for installation, making setup incredibly simple.
3 reasons why the Spindle Actuator is perfect for your project:
- Can replace hydraulic and pneumatic systems 1:1
- Only a power cable required for installation
- Precise control even under high loads

Your advantages
High safety
In the event of a power outage, the Screw Jack can't reset itself, thereby protecting both the machine and the operator.
Saving costs
Screw Jacks have up to 70% lower energy consumption compared to pneumatic and hydraulic systems.
High service life
For example, an HMC gearbox can achieve a long lifespan through a longer screw thread in the worm gear and the use of wear-resistant copper alloys.
Short cycle time
The High-Speed Screw Jack (KH) easily achieves stroke speeds of over 300 mm/s due to its bevel gear transmission.
High efficiency
The high efficiency of the gearbox in a High-Speed Screw Jack reduces heat generation, allowing for continuous operation in 24/7 shifts.
Easy installation
Screw Jacks are delivered as a complete system and can be directly integrated at the installation site.
