Why spheroidising is done for ball in the bearings?

Answer / bajrangi mishra
Spheroidising changes cementite from a lamella formation to
a formation based on an alpha ferrite matrix with particles
of spheroidal cementite (Fe3C)embedded. This resulting
steel has improved ductility and toughness compared to the
original steel with reduced hardness and strength.
This is done for ball bearings to avoid non-elastic
deformation of balls.

Answer / munendra kumar
it is done to reduce stress
concentration by making
spheroidised (round) grain
structure.because bearing are
subjected to the fatigue load
during its operation.stress
conc. is very dangerous in
fatigue load.
