Compact 8mm stepper linear slider designed for precise shorttravel positioning in DIY camera and small automation projects. The unit combines a 2phase 4wire stepper drive concept with a screw shaft and moving block to translate rotary steps into smooth, repeatable linear motion over a 10mm stroke. Why you need this Delivers controlled, repeatable linear movement where small, accurate adjustments matter — ideal for focus pulls, microslides, and lens positioning. Compact 8mm form factor fits tight assemblies and lightweight rigs, letting you add motorized linear motion without bulky hardware. Ready for integration into hobby and prototyping systems that use standard 2phase stepper motor control. Key benefits Precise shortstroke motion: 10mm travel provides fine adjustment range for closefocus, calibration, or small mechanical adjustments. Simple electrical interface: 2phase, 4wire configuration lets you drive the unit with common stepper drivers and controllers for accurate step or microstep control. Integrated screw shaft and moving block: converts rotary input into stable linear travel with minimal setup, reducing time spent on mechanical design. Main features and attributes Shaft diameter: 8mm — compact and suitable for small assemblies. Motor configuration: 2phase, 4wire stepping arrangement for straightforward driver compatibility. Linear mechanism: screw shaft with moving block translates rotation to linear motion. Stroke length: 10mm total linear travel for precise micropositioning. Application focus: marketed and sized for DIY camera use but adaptable to other small automation tasks. Compatibility and usage Designed to work with standard stepper motor drivers and controllers that support 2phase, 4wire motors. Use appropriate driver current and stepping settings for performance. Mechanical integration is straightforward: mount the slider in a compact frame, couple the rotary drive to a compatible motor or driver, and adjust motion via your controller. Use cases DIY camera focus/timelapse rail: add motorized microfocus control or fine axial movement for macro or timelapse photography. Small automation and prototyping: precise positioning for sensors, lenses, or test fixtures where a short, repeatable stroke is required. Educational and hobby projects: learn and demonstrate stepperdriven linear actuation in robotics or motioncontrol experiments. What to expect in operation Smooth, incremental linear movement when paired with an appropriate stepper driver and controller. Short, repeatable strokes that simplify fine adjustments and calibration tasks. Compact integration into lightweight rigs without large mechanical overhead. Notes for integration Ensure your stepper driver matches the 2phase, 4wire configuration and is set to suitable current and step settings. Verify mechanical mounting and alignment to avoid binding and to maximize repeatability across the full 10mm stroke. This 8mm, 2phase, 4wire stepping linear slider with screw shaft and 10mm moving block stroke is a compact, practical solution for adding precise shortrange linear motion to DIY camera builds and small automation projects.
