TR8x8 Metric Anti Backlash Lead Screw Nut

This TR8x8 anti-backlash metric lead screw nut is compatible with our 8mm diameter TR8x8 range of precision leadscrews. The diameter and pitch offer a great combination of high torque and speed capabilities, which is why it is one of the most used and popular leadscrew and nut combination for 3D printers, CNC machines, and other linear motion equipment. All high-end 3D printers make use of TR8x8 leadscrews for their Z-axis motion, resulting in consistent and accurate layer resolution and movement.

This brass nut features a round flanged surface with four 3.5mm holes, making mounting a breeze to the rest of your machine. The nut has a pitch of 2mm, with four starts, resulting in a lead of 8mm. This means that there is 8mm of travel per revolution of the leadscrew.

How the anti-backlash mechanism works?

The assembly consists of a main nut body and a secondary ring. There is a spring in-between the two which force each part against opposing flanks of the screw thread, effectively creating a bias which takes up any backlash during movement.
