Uses 4 screws! About twice the normal speed. Integrated gearbox and screw shaft. A "screw jack" that replaces conventional hydraulic and pneumatic equipment.
The "screw jack" integrates a speed reducer and a screw shaft. It is ideal not only for lifting but also for pushing, pulling, and tilting actions. Synchronous operation is possible, allowing multiple units to be connected and operated together. Of course, it can be powered by a single drive source (such as a motor). It uses high-precision manufactured gears to achieve silent operation and long lifespan. >>> Do you have any of these problems? <<< /By replacing with a jack and electrifying it, all issues can be resolved/ Oil leaks, vibrations, and maintenance work caused by hydraulic products Preparation of auxiliary equipment (compressors, hoses, piping) due to pneumatic and hydraulic products Insufficient power due to pneumatic equipment, etc. ■-----Custom-made products available-----■ Please consult with our sales representative. For example… - I want to use it in high (or low) temperature environments - I want to use it in food machinery - I also want an adapter for the motor - I want to use it outdoors, etc. ■-----We will bring samples!-----■ If you are interested, please contact us below or reach out to our sales office (TEL 03-6363-3163). *For more details, please refer to the PDF materials or feel free to contact us.
