There are at least 6 common types of bearing, each of which operates on different principles:
Plain bearing, consisting of a shaft rotating in a hole. There are several specific styles: bushing, journal bearing, sleeve bearing, rifle bearing, composite bearing;
Rolling-element bearing, in which rolling elements placed between the turning and stationary races prevent sliding friction. There are two main types:
Ball bearing, in which the rolling elements are spherical balls;
Roller bearing, in which the rolling elements are cylindrical, taper or spherical rollers;
Jewel bearing, a plain bearing in which one of the bearing surfaces is made of an ultrahard glassy jewel material such as sapphire to reduce friction and wear;
Fluid bearing, a noncontact bearing in which the load is supported by a gas or liquid (i.e. air bearing);
Magnetic bearing, in which the load is supported by a magnetic field;
Flexure bearing, in which the motion is supported by a load element which bends.
