FUYU FSL40 Version 2.0 Linear Guide Table with 150mm Stroke
The FSL40 Series uses a fully aluminum linear rail structure paired with a G1610 ballscrew for strength and corrosion resistance. Accuracy is specified up to ±0.02mm, with loading capacities around 25 kg horizontally and 20 kg vertically. A Nema 23 (5756) stepper motor drives the system, with speeds up to 1200 rpm. Maximum speeds reach 255 mm/s without loading. If higher performance is required, a 400W servo motor option is available on request.
Key features include a compact module design, low operating noise, and compatibility with common CNC platforms. The package is suitable for precise positioning tasks in small to mid-size automation projects.
FUYU FSL40 Version 2.0 Linear Guide Table—600mm Stroke
This longer stroke variant extends the same robust construction: a fully aluminum linear rail with a G1610 ballscrew, delivering excellent strength and rust resistance. It shares the ±0.02mm accuracy and 25 kg horizontal / 20 kg vertical loading capacities. Noise remains minimal during operation, and the Nema 23 stepper provides reliable drive performance. For applications requiring faster motion, the provider notes an option to upgrade to a 400W servo motor for higher top speeds.
Applications span CNC milling, laser systems, and robotic positioning where a longer travel range and dependable repeatability are essential.
RATTMMOTOR EBX1605 200mm CNC Linear Stage Actuator
This compact base uses an 2080 profile for structural stiffness, with a Nema23 motor at the front end and a double optical axis design. The 200mm working length suits compact CNC router builds and multi-axis configurations. The stage includes an 80x50mm slider, with embedded linear bearings to maintain uniform axial force and positional accuracy. The design supports easy installation and flexible mounting options for DIY projects and automation setups requiring precise small-range motion.
Performance notes highlight stable operation and robust bearing support to preserve accuracy over time, making it suitable for hobbyist to light-industrial deployments where placement precision matters.
RATTMMOTOR EBX1605 400mm CNC Linear Stage Actuator
The 400mm variant extends the same compact base and double optical axis concept, offering a longer travel option for larger fixtures or gantry systems. It uses an 80x50mm slider to ensure smooth, accurate movement and easy integration with multi-axis configurations. The CBX1605 family’s 1605 ball screw contributes to precise positioning at moderate speeds, while the motor and coupling arrangement maintains alignment under load. This model is suitable for mid-size automation tasks that require more travel without a heavy, bulky actuator.
Considerations for this model include compatibility with existing drive electronics, the need for proper grounding and cooling in higher-speed operation, and attachment methods for reliable mounting in a CNC or robotic setup.
TOSEASTARS 12″ 300mm Stroke Linear Stage
The TOSEASTARS linear stage blends 1605 ballscrew technology with a fully aluminum structure, delivering rigidity and rust resistance. The stage has a 12-inch effective stroke, with a total length of around 16.5 inches. Horizontal loading capacity reaches 88 pounds (40 kg), while vertical loading tops at 20 kg, making it suitable for robotic grippers, CNC secondary axes, and lightweight automation tasks. The design emphasizes high-speed travel up to 500 mm/s and smooth motion at precision-required intervals.
Key considerations include dust protection with the included dust cover, overall footprint, and compatibility with Nema23 motors and standard mounting patterns used in hobbyist and professional CNC builds.
Buying Guide: Key Purchase Considerations
- Stroke length versus travel needs: Match the actuator stroke to your application’s required travel. Longer strokes enable broader work envelopes but may add weight and size.
- Load capacity and orientation: Evaluate horizontal versus vertical loading, ensuring the rail and screw can support operating loads with margin for dynamic motion.
- Accuracy and repeatability: Look for specifications such as ±0.02mm accuracy and low backlash for precise positioning tasks.
- Motor compatibility: Confirm whether your system uses a Nema 23 stepper or a servo motor, and verify screw pitch and mounting compatibility with your drive electronics.
- Material and corrosion resistance: Aluminum rails with rust-resistant screws extend service life in varied environments.
- Noise and thermal performance: Lower noise operation is beneficial for lab or office spaces; consider cooling needs for higher-speed or continuous use.
- Mounting options and versatility: A stage with multiple mounting holes and easy attachment points simplifies integration into multi-axis setups.
- Upgrade paths: Some models offer higher-performance servo options; assess whether future upgrades fit your project roadmap.
- Maintenance and protection: Dust covers and sealed guides reduce debris intrusion, extending screw and bearing life.
