Bevel jacks (Ball screw)
BX Series
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.
