Bearing is defined as the acute angle that is measured between the reference meridian and the given line. The line is measured either from the north or south towards east or west that would give an angle less than 360 degrees.

Different bearing types have different operating speed limits. Speed is typically specified as maximum relative surface speeds, often specified ft/s or m/s. Rotational bearings typically describe performance in terms of the product DN where D is the mean diameter (often in mm) of the bearing and N is the rotation rate in revolutions per minute. Generally, there is considerable speed range overlap between bearing types. Plain bearings typ…
