✔️ 25mm lead screw 1960mm span with motor brackets included
This complete motion setup gives you smooth linear travel for your custom machining projects. You can mount it directly onto a standard Nema three four stepper frame. The design keeps vibration down while you cut hard materials.
✅ Core shaft measures twenty five millimeters across which equals one inch thick for rigid load handling ✅ Travel distance hits nineteen hundred sixty millimeters along with seventy seven point one seven inches of total stroke ✅ Lead pitch sets at four millimeters per rotation adding zero point one five seven inches of thread spacing ✅ Coupler bore opens at fourteen millimeters inside matching zero point fifty five one inches for gear inputs💡 What steps help you mount and care for a CNC ball screw linear actuator setup properly? Proper alignment makes a huge difference when you install a heavy duty ball screw drive for fabrication. - Bolt the cast steel supports tight so the shaft runs straight without wobbling under load - Clean the threads daily and pack fresh grease every quarter to stop grinding and heat buildup - Double check the coupler grip if you swap motor plates to keep torque transfer solid - Watch for chip piles near the nut tube to protect the recirculating balls from damage
