bearing

Bearings are common rotating mechanical components in machinery, and their function is similar to the joints of the human body, helping the machinery achieve rotational motion. Bearings can reduce friction through ball bearings, and there are bearings almost wherever there is rotation. Although bearings are small, they encompass comprehensive knowledge from multiple disciplines such as mathematics, physics, materials, heat treatment, precision machining, and numerical control technology.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
