PSG5S-100W Dual Carriage Ball Screw Linear Actuator | High Rigidity Precision Linear Module

PSG5S-100W Dual Carriage Ball Screw Linear Actuator

The PSG5S-100W is a compact, high-rigidity dual-carriage linear actuator built for precision automation applications where space is limited but load capacity and stiffness cannot be compromised. It features a φ12 mm C7 precision ball screw with a 2 mm lead, driven by a 100 W AC servo motor, delivering a rated thrust of 854 N and ±0.01 mm repeatability. The dual-carriage design doubles the guide support points, significantly improving moment stiffness and load distribution compared to single-carriage modules — making it a strong candidate for vision inspection, dispensing, and light assembly tasks.

Core Advantages

• Maintain ±0.01 mm repeatability – ensures consistent positioning for precision inspection and assembly.
• Carry up to 30 kg horizontally – dual carriage design distributes load across two guide blocks for improved stability.
• Generate 854 N rated thrust – 2 mm lead and 100 W servo provide ample force for pressing and light machining.
• Reach 100 mm/s traversing speed – sufficient for short-stroke, high-precision indexing cycles.
• Cover strokes from 25 to 325 mm – ideal for compact workstations and multi-axis systems.
• Support vertical loads up to 10 kg – with appropriate duty cycle and acceleration.
• Integrate with major servo brands – compatible with Mitsubishi, Panasonic, and Delta 100 W servos.
• Flexible motor mounting – exposed, bottom, left, or right positions to fit machine layouts.

Design & Performance Highlights

The PSG5S stands out for its dual-carriage design — two guided blocks mounted on a single carriage plate, effectively doubling the bearing support points compared to conventional single-slider modules. This arrangement significantly improves resistance to moment loads in pitch and yaw directions, making the actuator particularly suitable for cantilevered tooling or applications where the load center is offset from the carriage center.

The φ12 mm ball screw is paired with a preloaded nut to eliminate backlash, and the compact 8 × 8 mm coupling accommodates minor motor shaft misalignment. The extrusion profile is machined with precision reference surfaces, ensuring parallelism between the screw axis and guide rails without field alignment. Four motor mounting configurations (exposed, bottom, left, right) allow the actuator to fit into tight machine enclosures.

Why Choose the PSG5S-100W?

For applications where machine footprint is at a premium but moment stiffness cannot be sacrificed, the PSG5S-100W offers a practical solution. Its 60 mm width and short carriage length allow dense packaging in multi-axis systems, while the dual-carriage design delivers significantly better resistance to moment loads than single-carriage modules of comparable size.

Compared to the larger PSG8S-400W, the PSG5S trades speed (100 mm/s vs. 250 mm/s) and stroke length (325 mm vs. 450 mm) for a more compact footprint and lower system cost — making it an ideal choice for inspection stations, dispensing machines, and light assembly cells where space is limited but precision remains critical.

The 2 mm lead and 854 N thrust combination provides high force density in a small package, enabling pressing or insertion operations that would typically require a larger actuator. And with support for Mitsubishi, Panasonic, and Delta 100 W servos, you can standardize on a single motor family across your machine designs.
