Brass ZAxis Screw Coupling material and construction Made from brass to provide low friction, strong torque transmission, and torsional stiffness. Tightens connections with minimal inertial movement and reduces gaps between parts. Protects driven components and support bearings, helping to maintain alignment and performance even under repeated use. Designed to minimize the negative effects of large radial misalignment for more reliable operation. Improved printing performance Specifically designed for the Zaxis screw of the axis system, reducing printing issues caused by hot bed swing during operation. Improves stability and accuracy, contributing to more reliable and precise printing results. Compatibility and installation ready Diameter: 22 mm; center distance between the two mounting holes: 16 mm. Compatible with many devices that use a T8 Zaxis screw and a 16 mm centerdistance mounting hole screw nut. Important: measure your screw nut's installation hole distance before to confirm compatibility. Reliable, longlasting performance Brass construction delivers consistent performance under the continuous demands of use in Zaxis assemblies. Built to withstand regular use without compromising functionality. 23 practical use scenarios Upgrading a desktop 3D printer's Zaxis to reduce bed tilt and improve layer alignment, resulting in steadier prints with fewer quality issues. Replacing or upgrading worn Zaxis couplings in DIY 3D printer builds to restore stability and prolong service life. Integrating into small CNC or multiaxis projects that use a T8 Zaxis screw and a 16 mm hole spacing to achieve smoother motion and reliable coupling.
