SPM (Super Precision Machine Cut) titanium gear series spur gear screw. Using a lightweight / high-rigidity titanium material, Reve D has designed a screw specialised for attaching the spur gear.
In addition to improving rotational efficiency by reducing weight, the installation accuracy of the spur gear is greatly improved by providing a cylindrical section optimized for fixing the spur gear at the root of the M3 thread, reducing unnecessary vibration!
