4. A bearing is a machine element that constrains
relative motion and reduces friction between
moving parts to get the desired motion.

6. ROLLING ELEMENT BEARING
A rolling-element bearing, also known as a
rolling bearing, is a bearing which carries a load by
placing rolling elements (such as balls or rollers)
between two bearing rings called races. The relative
motion of the races causes the rolling elements to roll
with very little rolling resistance and with little sliding.
7. TYPES OF ROLLING ELEMENT BEARING
CYLINDRICAL ROLLER BEARING
DEEP GROOVE BALL BEARING
NEEDLE ROLLER BEARING
SELF-ALIGNING BALL BEARING
SPHERICAL ROLLER BEARING
ROLLER THRUST BEARING
8. DEEP GROOVE BALL BEARING
Deep groove ball bearings are probably the most
common rolling element bearings used since they
are durable and easy to maintain.
They are available in single and double row balls, and
open and sealed units.
They are also suitable for high speed applications.
