PINSI PSG8S Precision Single-Axis Linear Module | High-Speed, High-Precision Ball Screw Linear Slide
PINSL PSG8S Precision Compact Single Axis Linear Stage
The PSG8S is a compact, high-rigidity single-axis linear module designed for precision positioning applications in industrial automation, CNC equipment, and inspection systems. It features a φ16 mm C7 precision ball screw with a 5 mm lead, delivering a rated thrust of 683 N and ±0.01 mm repeatability. With a maximum stroke of 450 mm and support for dual-carriage configurations, it is an ideal choice for applications where short travel, high stiffness, and cost-effective precision are required.
Core Advantages
- Maintain ±0.01 mm repeatability – precise positioning for inspection, assembly, and light machining tasks.
- Deliver 683 N rated thrust – 5 mm lead and compatible servo drive provide ample force for most light-to-medium duty automation.
- Maximize stiffness in a compact footprint – 80 mm wide extrusion and short carriage design minimize deflection under load.
- Support dual-carriage configurations – handles horizontal loads up to 50 kg and vertical loads up to 15 kg.
- Reach 250 mm/s traversing speed – sufficient for fast indexing in short-stroke cycles.
- Integrate with major servo brands – compatible with Mitsubishi, Panasonic, Delta, and Yaskawa servos.
- Flexible motor mounting – left, right, bottom, or exposed positions to fit machine layouts.

Design & Performance Highlights
The PSG8S is engineered for applications that prioritize stiffness and positional stability within a compact envelope. Its 80 mm width profile and short carriage length allow dense packing in multi-axis systems, while the wide guide rail base resists moment loads in pitch and yaw directions — essential for single-axis cantilever setups or as a Z-axis in gantry systems.
The 5 mm lead ball screw is paired with a preloaded nut that eliminates backlash and ensures bidirectional positioning within ±0.01 mm. The motor mounting bracket supports four orientation configurations (left, right, bottom, and exposed), enabling the stage to adapt to various machine layouts without custom fabrication. Optional dual-carriage configurations increase load capacity and rigidity for applications requiring heavier payloads or extended tooling.

Why Choose the PSG8S?
For automation engineers designing compact workstations or gantry Z-axes, the PSG8S offers a stiffness-to-footprint ratio that is difficult to achieve with larger-profile stages. Its 80 mm width and short carriage length allow dense packaging in multi-axis systems, while the 5 mm lead delivers 683 N of thrust — sufficient for most pick-and-place, dispensing, and light assembly operations.
Compared to the higher-thrust PSG8S-400W configuration (1388 N), this version offers a cost-effective alternative for applications that do not require maximum force output. It shares the same mechanical structure and rigidity, but is paired with a lower-power motor or drive configuration, reducing system cost while maintaining the same ±0.01 mm repeatability and smooth motion quality.
When compared to belt-driven modules at a similar price point, the PSG8S's ball screw drive provides superior thrust at low speeds and inherent position holding without power — a critical advantage for inspection or assembly stations where part stability is essential.
