Description

Select Length

These trapezoidal (metric) lead screws pitch and diameter are a perfect combination of high torque and speed. This screw fits the bill for most machine designs and has become a standard on OpenBuilds.

Equipped a high pitch which provides a quick 8mm translation for every single revolution on the screw.

40mm is added to the length by standard. This is to allow the ACME rod to fit a standard length rail and have some extra mm sticking out and reach a pulley, coupler or other drive components.

It's a great power transmition choice for your build!

  • Tr8*8-2p (4 starts)
  • Lead Screw Diameter ∅ 8 (mm)

  • Actual Length: 250: 290mm; 500: 540mm; 750: 790mm; 1000: 1040mm; 1500: 1540mm

Please note: Long screws can wobble - but properly mounted with bearings at both ends and one or preferably two ACME nuts on the gantry plates this should not be any problem. Also you may experience that the bearing can be difecult to slide on. If so please use very fine grade sandpaper to remove and burrs from the threading.

An example steps settings for your control software would be 200 steps per millimeter if you are running the common 1.8 degree steppers and your stepper driver is set to 1/8 step mode.

To calculate different step scenarios for your control software have a look at these handy steps calculators: Here and here

 NOTE: Because this lead has 4 starts with 2mm pitch between each this means the pitch will be 8. So 8 is what you would use for the pitch setting in the steps calculators..
