Dead Nuts Accurate Cross Roller Motorized Linear Stage With 75Mm Travel And Solid 20Kg Load Capacity Smooth Stepper Motor Drive Aluminum Alloy Platform For Tight Workshop Labs And Precision Tasks

Single motorized cross roller stage for accurate shop tasks
✔️ 75mm stroke, 20kg hold, 90 by 110mm plate, 1.7kg build

This single unit motorized linear stage pairs a ground lead screw with crossed roller guides to deliver smooth, repeatable motion along one axis. You will find it most handy in optical alignment rigs, camera mounts, and compact pick-and-place jigs where steady positioning beats raw speed.

✅ Two phase 1.8 degree stepper motor drives the 1mm pitch screw
✅ Crossed roller bearing setup handles 20kg vertical load smoothly
✅ Hard black anodized aluminum platform measures 90 by 110mm to 3.5 by 4.3 in
✅ 75mm travel rail to 2.95 in stroke pairs with built-in limit switches

💡 Why do engineers swap traditional sliders for crossed roller tracks?
Picking a crossed roller arrangement proves handy whenever you need rigid support without sacrificing micron level tracking.

- The intersecting path spreads rolling friction evenly across four directions to block tilt and yaw drift.
- Paired with a grinding lead screw, it turns steady electrical pulses into exact fractional millimeter jumps.
- Preloaded rail elements lock out play early so repeatability stays inside five micron tolerances.✝️
