Miniature bearings are smaller than traditional bearings and typically have holes with less than 10mm diameters. Miniature bearings are capable of handling smaller torque loads. In general, bearings are small components placed between moving parts in order to reduce friction from movement.
When the two moving parts roll over each other rather than rubbing against each other, the amount of friction created is much smaller. The small balls located in the rings of the miniature bearing "bear" the weight of the load, which permits the machine to run smoothly.
There are two classifications for bearings: linear and rotary. These classifications are based on the motions for which they are designed. A linear miniature bearing moves in a straight line. These bearings are used for pushing and pulling motion, like that of a drawer opening and shutting. A rotary bearing, in comparison, is designed for radial motion, like that of a wheel spinning.
