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

ENGINEER), for giving me such a great inspiration for successful

completion of my project without whom it would have been impossible

to attain success.

I would also like to express my profound sense of gratitude to Mr.

UMED SINGH (Faculty in Charge) who gave me guidance for

successful completion of report.

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.

Rollers is high carbon

high chromium i.e. SAE

52100. And for cage orretainers low carbon

steel is used.

The material required forInner ring, outer ring and

roller is SAE 52100.

Chemical composition ofSAE 52100 is

Carbon -0.95 to 1.05%

Silicon -0.25 to 0.40%

Chromium -1.40 to 1.60%

Sulphur -0.020% max.

Phosphorous -

0.025% max.


11/14

Nickle - 0.35% max.

Copper - 0.25% max. Lead - 0.02% max.

Material required for cages are cold rolled

carbon steel strip.

Chemical composition of CRCS strip is,

Carbon - 0.10%

Manganese - 0.25 to 0.50%

Sulphur - 0.40% max. Phosphorous - 0.04% max.

Chromium - 0.10% max.
