Available in 10 to 100 kN types! A new integrated design of reducer and screw shaft. A "mechanical screw jack" that replaces conventional oil and pneumatic cylinders.
The "screw jack" integrates a reducer and a screw shaft. It is optimal not only for lifting and lowering but also for pushing, pulling, and tilting. With a self-locking feature (fall prevention), it can maintain its position even without brakes. (Note: In some cases, it may not be able to hold its position.) It uses high-precision manufactured gears, achieving silent operation and long lifespan. >>> Do you have any of these problems? <<< / By replacing it with an electric jack, all issues can be resolved / Oil leaks, vibrations, and maintenance work from hydraulic products Preparation of auxiliary equipment (compressors, hoses, piping) from pneumatic and hydraulic products Insufficient power from pneumatic equipment, etc. ■----- Custom-made products available -----■ Please consult with our sales representatives. 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 motors - I want to use it outdoors, etc. ■----- We will bring samples! -----■ If you are interested, please contact us using the information below or reach out to our sales office (phone 03-6363-3163). * For more details, please refer to the PDF document or feel free to contact us.
