ABSTRACT
A bearing is a machine element which supports another moving machine element (known as journal). It permits
a relative motion between the contact surfaces of the members, while carrying the load. A little consideration
will show that due to the relative motion between the contact surfaces, a certain amount of power is wasted in
overcoming frictional resistance and if the rubbing surfaces are in direct contact, there will be rapid wear. In
order to reduce frictional resistance and wear and in some cases to carry away the heat generated, a layer of
fluid (known as lubricant) may be provided. The lubricant used to separate the journal and bearing is usually a
mineral oil refined from petroleum, but vegetable oils, silicon oils, greases etc., may be used. Bearings can be
split into two groups: Rolling bearings and Sliding bearings. Rolling bearings attempt to eliminate friction and
sliding between surfaces in a junction by introducing interfaces such as balls or rollers which rotate or roll in
as opposed to sliding. Examples of this type of bearings are axial ball and roller bearings.
