BX series bevel jacks (Ball screw)
Features
Easy synchronized operation
System design such as the simultaneous operation of multiple jacks is easy.
Optimal for low-speed operation
The driving system has less noise because machinery can be driven at a lower input speed.
High-efficiency
High efficiency is achieved by driving machinery with a bevel gear.
Easy to use
Easily select the optimal screw for each application with both trapezoidal screws and ball screws standardized.
