Such bearings should be equipped with the shaft position control system, which adjusts the fluid pressure and consumption according to the rotation speed and shaft load. [4] In fluid-dynamic bearings, the bearing rotation sucks the fluid on to the inner surface of the bearing, forming a lubricating wedge under or around the shaft.
Roller bearings are the earliest known type of rolling-element-bearing, dating back to at least 40 BC. Common roller bearings use cylinders of slightly greater length than diameter. Roller bearings typically have a higher radial load capacity than ball bearings, but a lower capacity and higher friction under axial loads.

Journal (friction, radial or rotary) bearing: This is the most common type of plain bearing; it is simply a shaft rotating in a hole. [3] In locomotive and railroad car applications a journal bearing specifically referred to the plain bearing once used at the ends of the axles of railroad wheel sets, enclosed by journal boxes .
In the case of ball bearings, the bearing has inner and outer races and a set of balls. Each race is a ring with a groove where the balls rest. The groove is usually shaped so the ball is a slightly loose fit in the groove. Thus, in principle, the ball contacts each race at a single point.
A 1903 advertisement for a Haynes-Apperson car. In 1895 the company had about 25 employees and sold about $2,000 of roller bearings each month. [5] That year Hyatt hired the 20-year-old Alfred P. Sloan as a draftsman. Sloan had recently obtained a degree from the Massachusetts Institute of Technology. [6]
