At the very outset, I am highly indebted to Dr. R.C.Ramola (Dean,
Faculty of Science and Technology), Dr. T.K.MANDAL (IP CO-
ORDINATOR) for giving me an opportunity to carry out my project at
esteemed organization. I would specially thank Mr. ABHISHEK
TRIPATHI (HR) for giving me time and guidance throughout the
project and I am personally thankful to Mr. JATIN (Senior

A bearing is a machine
element that constrains
relative motion andreduces friction between
moving parts to only the
desired motion.
Generally speaking, abearing is a device that isused to enable rotational orlinear movement, whilereducing friction and
handling stress

TYPES OF BE RING
Ball bearings
are extremely common because
they can handle both radial and
thrust loads, but can only
handle a small amount of
weight.

T PER ROLLER BE RING
This style of bearing is
designed to handle large
radial and thrust loads
as a
result of their load versatility,
they are found in car hubs
due to the extreme amount
of both radial and thrust
loads that car wheels are
expected to carry.

CYLINDRIC L ROLLER BE RING
Cylindrical Roller Bearings areseparable radial roller Bearings.Bearings are available withpressed steel cage or machinedbrass cage.
The Rollers and Cage assemblyis generally located on the
raceway having two integralflanges and the other raceway isseparable.
Thus the O/R and I/R can bemounted separately.

SPHERIC L ROLLER BE RING
Spherical roller bearings are
made for heavy-duty
applications. They feature two rows of
symmetrical barrel rollers
which can align freely in the
spherical outer ring raceway,thus compensating for shaft
deflections and misalignment
of the bearing seats.
