The early form of linear motion bearings was a row of wooden poles placed under a row of pry plates. Modern linear motion bearings use the same working principle, but sometimes balls are used instead of rollers. The simplest rotary bearing is a sleeve bearing, which is just a bushing sandwiched between the wheel and the axle. This design was later replaced by rolling bearings, which replace the original bushing with many cylindrical rollers, each rolling element is like a separate wheel.
