The main feature of our wheels for 3D printers and other projects is unrivaled ease of movement. This became possible with the use of high quality bearings from Japanese manufacturers, made according to ABEC5 (Class-5 / P5) standards.
Bearings of the EMQ (Electric Motor Quality) design are distinguished by their minimum rotation resistance and no pronounced backlash. So our wheels require minimal effort to set them in motion. This minimizes stress on motors, belts, idler rollers and significantly reduces inertia. The quality of our products will allow your projects to run flawlessly at the highest speed with the highest quality and repeatability.
In all other respects, our wheels fully comply with the OpenBuilds drawings and are manufactured with high precision.
