3. Definition
• Bearings are used in engine to support and protect
the rotating parts allowing them to turn freely.
• Connecting rod bearings and the crankshaft main
bearings are called split-sleeve types, which mean
they are in two halves, called inserts, slippers or
shells.

4. MaterialUsed
• Cummins main bearing is manufactured
using sintered bronze, which holds oil to reduce
friction, and various metals which are cast in
place to make a soft slippery surface for really
heavy shafts.

5. Features:
• Anti-corrosive
• Anti-friction resistant
• Good tensile and compressive strength
• Thermal resistant property

6. Functions:
• Reduces Friction
• It holds the crankshaft in place and prevents the forces
created by the piston, transmitted to the crankshaft by the
connecting rods from dislodging it.
• It forces the crank to convert the reciprocating movement
into rotation.
