QINIZX 90mm Stroke Linear Rail Actuator
The 90mm stroke rail features a compact metal main body and a plastic slider, designed for small teams and tight spaces. It operates with a DC drive voltage of 5-12V and draws up to 800mA, offering stronger force at higher voltage with increased heat. The 18-degree step angle enables fine positioning. The stage measures 4.31″ x 0.59″ x 0.98″, with an effective stroke of 3.1″. A dedicated stepper motor driver board is required for operation; search for B09BTWQPTB to purchase. Wiring is A and B channels per color: Blue A+, Black A-, Red B+, Yellow B-.
QINIZX 48mm Stroke Linear Stage
This smaller linear rail is designed for compact builds, offering a 48mm stroke and a compact overall footprint. It tolerates 5-12V across 100-300mA, with an 18-degree step angle. The stage includes motor integration with a total size of about 3.2″ x 0.98″ x 0.78″ and a sliding block of 0.98″ x 0.39″ x 0.55″. The drive requires a compatible stepper motor driver board; look up B09BTWQPTB for compatibility. Wiring uses Yellow A+, White A-, Red B+, Black B-.
FUYU FSL40 Linear Guide Version 2.0
The FSL40/FSK40 module uses an all-aluminum linear rail with a G1610 ballscrew, delivering strength and rust resistance with accuracy up to ±0.02mm. It supports horizontal loads up to 25 kg and vertical loads up to 20 kg, with low noise operation. The unit pairs with a NEMA23 5756 motor and can reach speeds up to 1200 rpm, withoretical max speeds up to 255 mm/s without loading. For higher performance, a 400W servo option can be discussed with the seller.
Befenybay 100mm Travel Linear Stage
This 100mm travel stage uses SFU1605 screws with a NEMA17 motor, offering high precision and a horizontal load capacity up to 30 kg. Vertical load capacity reaches 15 kg, with repeat positioning accuracy of ±0.03 mm and speeds up to 100 mm/s. The combination provides stability for CNC routing, milling, or laser engraving tasks requiring reliable linear motion.
RATTMMOTOR ZBX80 600mm Stage
Offering a long 600mm stroke, the ZBX80 stage supports substantial loads with 80 kg horizontal and 20 kg vertical capacity. The unit combines an 80 mm width aluminum base and a robust 80×50 mm slider with a chrome-plated ball screw for improved hardness and load-bearing performance. Total actuator length with motor is 830 mm, enabling larger multi-axis configurations for CNC or automated systems.
RATTMMOTOR EBX1605 100mm Stage
The EBX1605 100mm stage features a double optical axis design with a compact 2080 profile base and a 1605 lead screw, integrated with a Nema23 motor. It is designed for stable operation with side mounting grooves for easy installation and multi-axis expansion. The 100mm travel length provides a versatile platform for precise X-Y Z movements in DIY CNC or robotics projects.
Buying Guide
- Stroke length vs. travel needs: Longer strokes enable larger work areas but may add weight and complexity. Choose a stroke that matches your project’s required travel range.
- Load capacity: Consider horizontal and vertical load requirements. Heavier machines need sturdier rails and ballscrews to prevent deflection and maintain accuracy.
- Motor and drive compatibility: Ensure your driver board supports the chosen stepper voltage/current. Some units require a separate driver module for operation.
- Material and finish: Aluminum rails resist corrosion and weigh less, improving speed and efficiency. Stainless or high-grade aluminum options offer durability for harsh environments.
- Accuracy and repeatability: Look for specs like ±0.02–0.03 mm accuracy for reliable engraving and precise positioning in CNC tasks.
- Modularity: Some systems are designed for multi-axis configurations; check mounting patterns and available adapters to plan future expansions.
- Cost vs. performance: Higher-stroke, higher-load systems cost more but yield better stability for demanding tasks; balance your budget with required precision.
These selections provide a spectrum of capabilities from compact, light-duty stages suitable for small-team projects to robust, multi-axis configurations for more demanding CNC or engraving setups. When choosing, align the actuator’s stroke, load capacity, and motor compatibility with your specific application to optimize performance and reliability.
