PSG12-400W High Speed Single Axis Linear Stage

The PSG12-400W Series is a servo-driven single-axis linear module engineered for high-speed positioning and precision automation. It features a φ16 mm C7 precision ball screw, a 400 W AC servo motor, and a flexible range of lead options (5–32 mm) that allow users to optimize between speed and thrust. With a maximum stroke of 1250 mm and ±0.01 mm repeatability, it is well suited for pick-and-place, inspection, and multi-axis XYZ platforms.

Core Advantages

• Achieve ±0.01 mm repeatability – holds positioning accuracy across the full stroke for precision automation tasks.
• Reach speeds up to 1600 mm/s – 32 mm lead option delivers high throughput for fast-cycle applications.
• Carry horizontal loads up to 110 kg – 5 mm lead configuration provides ample thrust for heavy payload transfer.
• Support vertical loads up to 33 kg – with appropriate lead selection and brake option.
• Choose from 4 lead options – 5 / 10 / 20 / 32 mm to balance speed and thrust per application.
• Integrate with major servo brands – compatible with Mitsubishi, Panasonic, Delta, and Yaskawa.
• Flexible motor mounting – exposed, bottom folded, left/right folded, or opposite side configurations.

Design & Performance Highlights

The PSG12-400W uses a rigid aluminum extrusion with integrated linear guide ways, machined to maintain parallelism between the screw axis and guide rails. The preloaded ball nut is factory-set to eliminate backlash, while the flexible coupling (10 × 14 mm) accommodates minor motor shaft misalignment and reduces stress on the screw bearings.

The modular motor bracket supports five orientation configurations — exposed, bottom folded, left folded, right folded, and opposite side — allowing the stage to fit into tight machine enclosures or multi-axis gantry arrangements. External sensor mounting grooves simplify the installation of home and limit switches, with NPN-type sensors pre-wired for immediate connection.

Why Choose the PSG12-400W?

For automation engineers seeking a balance of speed, payload capacity, and configuration flexibility, the PSG12-400W offers a practical combination rarely found in a single-axis stage of its footprint. Its φ16 mm screw diameter and 32 mm lead option enable 1600 mm/s travel speed, while the 5 mm lead option delivers 1388 N thrust and supports horizontal payloads up to 110 kg — giving you the flexibility to optimize for speed or force without changing hardware.

Compared to smaller-profile modules with 12 mm screws, the PSG12's larger screw diameter provides better torsional stiffness and resistance to deflection, particularly at extended stroke lengths above 800 mm. The modular motor mounting system allows field reconfiguration between five orientations, reducing the need for custom brackets when adapting to different machine layouts.
