PINSI High Torque Linear Stage PSG15
PINSI PSG15 is a high-performance heavy-load single-axis linear module designed for industrial automation and CNC equipment. It adopts a φ20mm C7 precision ball screw and supports multiple motor power options up to 750W, ensuring strong thrust and stable high-speed motion.
With stroke range up to 1200mm and multiple lead options (5/10/20/32mm), PSG15 provides flexible configuration for different motion requirements. It is widely used in robotic systems, gantry structures, inspection machines, and high-load positioning applications.
PINSL PSG15 High Torque Single Axis Linear Stage
The PSG15 is a heavy-duty single-axis linear module built for high-load and high-speed industrial automation. It features a φ20 mm C7 precision ground ball screw, supports up to 750 W servo motors, and delivers a maximum thrust of 2563 N — making it suitable for demanding applications such as CNC gantries, heavy-load pick-and-place, and large-format machining systems.
Core Advantages
- Generate up to 2563 N thrust – handles heavy payloads and high-resistance machining operations.
- Reach speeds up to 2000 mm/s – selectable lead options (5/10/20/32 mm) optimize speed vs. thrust for your specific cycle time requirements.
- Maintain ±0.01 mm repeatability – ensures consistent positioning accuracy under varying load conditions.
- Cover strokes from 50 to 1200 mm – accommodates a wide range of automation cell sizes.

Product Structure View
Design & Performance Highlights
The PSG15 is built around a high-rigidity aluminum extrusion profile that supports a φ20 mm ball screw and wide-base linear guide system. The carriage is machined with precision reference surfaces, ensuring parallelism between the screw axis and guide rails without requiring shimming or field alignment.
The preloaded ball nut is factory-set to eliminate backlash, while the flexible coupling (12 × 19 mm) 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), allowing the stage to fit into tight machine enclosures or multi-axis gantry arrangements.
Motor Configuration
The PSG15 accepts standard 750 W AC servo motors with 12 mm shaft diameters. Optional mounting brackets are available for Mitsubishi, Yaskawa, Panasonic, and Delta servo series. Four installation modes — motor left, motor right, motor bottom, and exposed (in-line) — provide flexibility for different system layouts.
Typical Applications
- Heavy-duty CNC automation systems (milling, drilling, routing)
- Industrial gantry robots with high payload capacity
- High-speed pick-and-place systems
- Inspection and measurement equipment requiring long travel
- Multi-axis XYZ platforms and custom automation cells
Customization Options
- Custom stroke lengths (outside 50–1200 mm range on request)
- Screw lead selection (5 / 10 / 20 / 32 mm) to optimize speed vs. thrust
- Motor mounting bracket for specific servo brands and models
- Motor orientation (left / right / bottom / exposed) – field configurable
- Integrated limit/home sensor kits (NPN/PNP, magnetic reed, or optical)
- Protective bellows or metal covers for dusty or coolant-laden environments
- Vertical orientation brake kits
- Special lubrication options for cleanroom or food-grade applications
Why Choose the PSG15?
For applications requiring both high speed and high thrust, the PSG15 offers a combination rarely found in a single-axis stage of its footprint. Its 20 mm screw diameter and 32 mm lead option enable 2000 mm/s travel speed, while the 5 mm lead option delivers 2563 N thrust for heavy cutting or pressing operations — giving you the flexibility to optimize for speed or force without changing hardware.
Compared to compact-profile modules with smaller screws (12–16 mm), the PSG15's larger screw diameter provides higher torsional stiffness and better resistance to deflection under load, particularly at extended stroke lengths above 800 mm. This makes it a reliable choice for gantry systems where the stage operates in cantilever or high-moment configurations.
