Alright, for the makers, CNC builders, and automation tinkerers out there – this linear stage is a solid little workhorse. It comes fully assembled with a NEMA23 stepper motor already mounted, so you can basically bolt it into your project and start moving stuff. The travel is 150mm (that's the effective movement length), and it uses a proper SFU1605 ball screw for smooth and precise motion – that's a 16mm diameter screw with a 5mm pitch, so one motor rotation moves the carriage exactly 5mm. The whole thing rides on square linear rails inside an enclosed housing, which helps keep out dust and chips – super handy for CNC routers or 3D printer builds. The stepper motor is a standard NEMA23 size: 57mm flange, 1.8-degree step angle, 1.2 N.m holding torque. It can handle a decent load too – up to 30kg horizontally or 15kg vertically. Positioning accuracy is pretty good for the price, around ±0.03mm repeatable. It's got M4 threaded holes on the carriage to mount your tool or workpiece. Speed range is about 0-100mm/s. Overall length is around 325mm. It's a direct, ready-to-go module for your X, Y, or Z axis, especially if you're building a small CNC machine, laser engraver, or any kind of automated sliding mechanism. Saves you the hassle of sourcing and aligning rails, screws, and motors separately. Just wire up the motor to your driver, bolt the stage down, and you're in business.
