VEVOR Linear Guide: 1000 mm Ball Screw Stage
Key features: 16 mm diameter ball screw with a 1000 mm effective stroke, integrated NEMA 23 stepper motor, high load capacity, and anti-corrosion coating. The unit supports horizontal loads up to 10 kg and vertical loads up to 5 kg, making it suitable for engraving machines, CNC milling setups, and other automated stages that need sturdy, repeatable motion. The anti-corrosion coating helps in humid environments and longer-term use.
Best for: Builders seeking a ready-to-run, motorized linear stage for mid-size CNC or engraving machines. This is a strong all-in-one option when you want a single unit with motor and robust motion.
Caution: The stated load ratings are contextual; ensure your overall system assembles with adequate support to avoid flex under peak travel. Mounting alignment is critical for maintaining precision over long strokes.
FUYU FSL40 Version 2.0: 100 mm Stroke Linear Guide
Key features: Fully aluminum structure with a G1610 ballscrew, accuracy up to ±0.02 mm, horizontal load up to 25 kg, vertical load up to 20 kg, and low-noise operation. This model ships with a version mix (V1 and V2) and uses a NEMA 23 compatible motor with speeds up to 1200 rpm. If you need higher speeds, a 400 W servo motor can be considered separately.
Best for: Projects requiring a compact yet precise linear stage with good load handling and relatively quiet operation, such as small CNC routers, laser engravers, or desktop milling units requiring quick, repeatable axis moves.
Caution: Compatibility with your specific mounting pattern can vary due to backplate differences between V1 and V2 versions. Verify mounting geometry before purchase.
ANWOK Ball Screw RM/SFU1605-600mm
Key features: 16 mm diameter ball screw, 600 mm length, includes a metal deflector ball screw nut housing and end supports. Built with CF54 steel, it offers wear resistance and low operating noise with high transmission efficiency. The system supports high axial forces per ball screw and provides accurate positioning with reduced stick-slip.
Best for: DIY CNC projects that require reliable, longer travel on the linear axis with straightforward installation and robust end supports, suitable for table-top mills or hobbyist CNC routers.
Caution: The package relies on compatible mounting hardware; confirm end supports and brackets match your frame before assembly to avoid misalignment.
TEN-HIGH Ball Screw RM1605: 600 mm
Key features: 16 mm diameter, 5 mm lead, length 600 mm, GCr15 steel, C7 accuracy, rolled thread manufacturing. It emphasizes high precision, low noise, smooth operation, anti-backlash design, and suitability for vertical use. The setup is noted for easy installation and long service life due to low friction and stiff performance.
Best for: Upgrading or building a precise linear stage where a stable, low-friction ball screw pair is preferred and where a motorless screw is acceptable for upgrade onto a separate NEMA motor or servo system.
Caution: As a motorless option, you will need to select and mount your own drive motor and coupler, which adds design considerations for belt or direct-drive setups.
RATTMMOTOR EBX1605: 500 mm Stage
Key features: 500 mm travel with a compact 2080-profile base. Includes a NEMA 23 motor, double optical axis design, and stable bearings for improved accuracy. The combination supports cross-table and multi-axis configurations, making it versatile for small CNC routers, engravers, or robotic arms.
Best for: Small to mid-size systems that demand an integrated motor solution with stable motion, especially when space is constrained or when a dual-axis arrangement is planned.
Caution: Ensure the base and motor mounting align with your frame geometry to avoid misalignment or binding during travel.
Buying Guide: How To Choose The Right Ball Screw Linear Actuator
- What stroke length do you need? Longer strokes enable bigger work areas but require sturdier support and alignment.
- What load will the axis carry? Consider horizontal vs. vertical loading, and factor dynamic forces during rapid moves.
- Do you need a motor integrated or separate? Integrated motors offer plug-and-play convenience; separate motors provide flexibility for upgrades.
- What accuracy and backlash tolerance are required? Higher precision systems reduce play, improving repeatability for engraving and milling tasks.
- What mounting pattern is compatible with your frame? Verify backplates, end supports, and mounting holes to prevent fit issues.
- Noise and speed considerations: If you operate in a noise-sensitive environment, choose models noted for low-noise operation and consider available speed ranges.
- Maintenance and environment: Rust-resistant coatings aid longevity in humid spaces; plan for preventive maintenance in dusty or cool room conditions.

FAQ
- What is a ball screw linear actuator? It combines a ball screw with a linear guide to provide precise, low-friction linear motion for automation and CNC tasks.
- Do I need backlash reduction? For high repeatability, consider models that advertise anti-backlash or preloaded ball nuts.
- Can these act as vertical axes? Yes, several models support vertical use but check their load ratings and mounting requirements.
- Is an integrated motor better? Integrated motors simplify wiring and mounting, but separate motors offer more flexibility for custom torque and speed control.
- What maintenance is required? Regular inspection of mounting, lubrication of the screw and bearings, and checking for corrosion in humid environments help extend life.
- How do I choose between 600 mm and 1000 mm strokes?
- 600 mm suits compact or modular builds; 1000 mm enables larger travel but requires sturdier framing and precise alignment.
