Project Description
This Ball screw jack load capacity from 1 ton to 100 ton. Highly efficient and optimized for higher speed, higher duty circle, and low noise operation.
- Option: Anti-Rotation, higher pitches available
- Translating(traveling screw) and rotating (traveling nut) configurations
- Move loads and apply force more efficiently than other machine screw actuators
- No self-locking! Because of the lack of friction, a motor brake is required.
- Best Material: tough ductile iron housings, high-performance ball screw, ball thrust bearings provide rugged reliability, high strength bronze worm gear
You can trust us on high quality, on-time delivery, controlled costs and reduced risk.
