{{main|Linear-motion bearing}}
Linear motion roller-element bearings are typically designed for either shafts or flat surfaces. Flat surface bearings often consist of rollers and are mounted in a cage, which is then placed between the two flat surfaces; a common example is drawer-support hardware. Roller-element bearing for a shaft use bearing balls in a groove designed to recirculate them from one end to the other as the bearing moves; as such, they are called ''linear ball bearings''<ref>{{Cite web|url=http://www.mcmaster.com/#catalog/116/1070|title = McMaster-Carr}}</ref> or ''recirculating bearings''.
