One each 10 start 25mm pitch Anti-Backlash Nut Fast Lead Screw
This leadscrew is custom manufactured for TrinityLabs to our specifications and is taylor made to be used for very fast and precise X and Y axis on 3d printers and CNC mills.
There is 320mm of travel on this screw after accounting for the length of the custom low profile rectangular antibacklash nut. The idler end is turned down to fit inside of a 605zz bearing and the motor end is turned down to 6.35mm or 1/4th" and fit in our Z Axis couplers we sell elswhere in the store.
The screws are 12mm diameter and the 10 start means they require less torque to go faster while the 25mm pitch means that for every 360degree rotation of the stepper shaft the leadscrerw nut moves a full 25mm on the screw. This is the same speed and pitch as the screws we use in the Aluminatus linear actuators on the X and Y axis and give very high speed performance as well as almost a full order of magnitude better repeatability and positional accuracy than GT2 belt driven axis.
+-0.02mm repeatability per meter of travel
Capable of 280mm/sec speed with double stack nema17 stepper motors and 390mm/sec speed with triple stack nema17's. When used with nema23's, speeds above 600mm/sec are easily achievable.
These are some of the fastest and highest quality leadscrews you can find for the best price around. Go ahead and have a look around and price out a 10 start, 12mm diameter, 25mm pitch 320mm travel screw including a constant force anti-backlash nut and you will find that most places want to charge you as much for just the anti-backlash nut as we charge for the leadscrew and the anti-backlash nut!
