When working with Linear Motion Components or CNC machines like engravers or 3D Printers, the ability to translate the rotational torque from a stepper motor into linear motion along a straight line is invaluable. This is why, in addition to our metal leadscrew nuts, we are also eager to offer customers an alternative choice in the form of POM or Delrin leadscrew nuts.

This Leadscrew nut, however, when compared to the standard TR8x8 Leadscrew POM Nut that we also stock, is designed with an extra part that is connected to the base unit via a spring, and then installed alongside the nut on the leadscrew. This is a relatively simple way of adding anti-backlash capabilities, as the secondary unit helps prevent any slippage or accuracy loss that inertia and weight can cause, which then translates to better z-accuracy and overall better quality prints. This is a great alternative to the classic Brass Anti-Backlash Leadscrew Nut, but also offers a lower friction coefficient and as such also typically lasts for a longer lifespan than brass as well.

The benefits of using POM (Delrin) instead of brass include the fact that Delrin offers reduced resistance due to friction, as well as a longer lifespan since POM is naturally self-lubricating. This results in less wear and tear but more consistent accuracy over time when compared to harder materials like brass.

Typical Applications for these TR8x8 Metric Lead Screw Anti-Backlash POM Nut:

These TR8x8 Metric Lead Screw POM Nut are typically used in CNC machine applications, and have been appearing more and more in 3D Printing due to the ever-increasing popularity of the industry. However, they are certainly not limited to this application, and many people argue that POM is actually far better than brass for actual CNC engravers and cutters, since the longer lifespan and low coefficient of friction ensures consistent accuracy even after months of solid usage.
