Features
- Built upon the 7STA03B series, this model integrates a grating ruler for closed-loop automatic control, enabling micron-level positioning accuracy when used with a motion controller.
- The high-precision ball screw drive system ensures smooth linear motion, excellent repeatability, and long-term stability.
- A three-bearing mounting structure secures the screw rod, minimizing axial displacement and ensuring reliable performance in high-speed reciprocating applications.
- The square-type linear guide, fully integrated with the base plate, provides high rigidity and load capacity, making it suitable for single-axis heavy loads or multi-axis configurations.
