PSG8 200W Ball Screw Linear Actuator | High Load Precision Linear Motion Stage
PSG8-200W Precision Ball Screw Linear Actuator
The PSG8-200W is a servo-driven linear actuator built for precision automation applications that require a balance of speed, stroke length, and cost-efficiency. It features a φ16 mm C7 precision ball screw with selectable leads (5/10/20 mm), driven by a 200 W AC servo motor, delivering a rated thrust of 683 N and ±0.01 mm repeatability. With a maximum stroke of 1100 mm and speeds up to 1000 mm/s, it is well suited for semiconductor manufacturing, CNC machinery, assembly automation, and inspection systems.

Design & Performance Highlights
The PSG8-200W uses a high-rigidity aluminum extrusion profile with integrated linear guide ways, machined in a single setup to ensure parallelism between the screw axis and guide rails. This manufacturing approach eliminates field alignment requirements and reduces installation time.
The preloaded ball nut is factory-set to eliminate backlash, while the flexible coupling accommodates minor motor shaft misalignment and reduces stress on the screw bearings. The motor mounting bracket supports four orientation configurations (left, right, bottom, and exposed), enabling the actuator to adapt to various machine layouts without custom fabrication. External sensor mounting grooves simplify installation of home and limit switches, with NPN-type sensors available as standard options.

Why Choose the PSG8-200W?
For automation engineers seeking a cost-effective servo-driven alternative to larger 400 W or 750 W stages, the PSG8-200W offers a compelling balance of performance and value. Its 200 W servo provides sufficient thrust (683 N) for most pick-and-place, dispensing, inspection, and light assembly tasks, while the 20 mm lead option enables 1000 mm/s traverse speeds — matching the throughput of many higher-powered stages in short-to-medium stroke applications.
Compared to stepper-driven modules of similar size, the PSG8-200W delivers smoother motion, higher dynamic response, and superior positioning stability at speed, thanks to the closed-loop servo control and encoder feedback. This makes it particularly suitable for applications requiring consistent velocity profiles, such as dispensing, scanning, or laser processing, where speed ripple can affect process quality.
The PSG8-200W shares the same mechanical platform as the higher-thrust PSG8S-400W, allowing engineers to standardize on a single mechanical design while scaling motor power according to application requirements — simplifying spare parts management and machine maintenance.
