PSG4-100W AC Servo Linear Stage | High-Speed Precision Ball Screw Actuator

PSG4-100W Compact High-Speed AC Servo Linear Stage

The PSG4-100W is a compact, high-speed single-axis linear stage engineered for precision automation applications where space is limited but throughput cannot be compromised. It features a φ10 mm C7 precision ball screw with selectable leads (2/5/10 mm), driven by a 100 W AC servo motor, delivering speeds up to 500 mm/s and ±0.01 mm repeatability. With a maximum stroke of 800 mm and a slim 44 mm width profile, it fits easily into tight machine enclosures, gantry systems, and multi-axis workstations.

Core Advantages

• Maintain ±0.01 mm repeatability – ensures consistent positioning for precision automation tasks.
• Reach speeds up to 500 mm/s – 10 mm lead option delivers high throughput for fast-cycle operations.
• Choose from 3 lead options – 2/5/10 mm to optimize speed, thrust, and resolution per application.
• Cover strokes from 50 to 800 mm – accommodates a wide range of automation cell sizes.
• Carry horizontal loads up to 25 kg – 2 mm lead configuration provides high thrust for light machining and pressing.
• Fit into tight spaces – 44 mm width profile allows dense packaging in multi-axis systems.
• Integrate with major servo brands – compatible with Mitsubishi, Panasonic, and Delta 100 W servos.
• Simplify installation with four motor mounting configurations (exposed, bottom, left, right).

Design & Performance Highlights

The PSG4-100W is built around a slim 44 mm wide aluminum extrusion that integrates the linear guide ways and ball screw support bearings in a single machined assembly. The entire unit is machined in one setup, which keeps the screw axis and guide rails parallel without requiring field alignment — a time-saver during installation.

The preloaded ball nut eliminates backlash, and the flexible coupling (7 × 8 mm) compensates for minor motor shaft misalignment. The motor bracket supports four orientation configurations (exposed, bottom, left, and right), allowing the stage to adapt to your machine layout without custom parts. External mounting grooves for home and limit switches come pre-machined, with NPN-type sensors offered as standard.

Why Choose the PSG4-100W?

For automation engineers designing compact workstations or gantry systems where every millimeter of width matters, the PSG4-100W offers a combination of slim profile (44 mm) and high speed (500 mm/s) that is difficult to find in competitive modules. Its 10 mm lead option delivers rapid indexing for high-cycle pick-and-place or inspection operations, while the 2 mm lead option provides 854 N of thrust for light pressing or insertion tasks — all within the same compact frame.

Compared to the PSG5S-100W (dual carriage, 60 mm wide, 325 mm stroke), the PSG4-100W trades some load capacity and rigidity for a narrower profile and longer stroke capability (800 mm). This makes it a better fit for single-axis transfer systems or gantry Z-axes where stroke length is the primary constraint and moment loads are moderate.

When compared to stepper-driven modules of similar size, the PSG4-100W delivers significantly smoother motion, better high-speed torque, and closed-loop positioning stability — advantages that translate directly to higher throughput and better process quality in demanding automation cells.
