Questions tagged [bearings]
A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts. The main use of bearings is to support a rotating shaft. There are several types of bearings, with different principles and rolling elements, for example: Ball bearing and roller bearing.
