We,
at Miniature Balls, have been manufacturing bearing balls
since our inception. Now, the production lines in our
plant have been streamlined with the addition of special
grinding and lapping machines. These machines have been
developed as a result of our own technical know-how, which
has accumulated during long years of experience in the
manufacture of steel balls. These machines make it possible
for us to produce high carbon chrome steel balls with
superior quality, both in terms of geometrical shape and
surface quality, so that, when used in ball bearings,
they demonstrate an extremely low level of running noise.
Raw material also plays very prominent role. The dynamic
properties of the chrome alloy steel balls as the rotating
element of ball bearings viz., abrasion resistance,
impact strength, pitting corrosion resistance, etc.
depends upon the metallurgical characteristics of their
raw material in addition to the grinding and lapping
results. We are exclusively using the highest-grade
vacuum degassed chrome alloy steel wires manufactured
in modern electric arc furnaces. All steel wires are
rigidly inspected before approval for use as basic raw
material.
Further, the steel balls are heat-treated in special continuous
furnaces which are managed under strict process control.
Working conditions are maintained so as to enforce the
optimum established limits verified by endurance tests,
x-ray diffraction analysis, etc. While our special grinding
and lapping procedure serve to minimize temper lines &
other surface defects, they also improve the abrasion
resistance of the finished balls. Our manufacturing range
for bearing balls is 1.5 mm diameter to 8.0 mm diameter
for high carbon chrome steel balls.
Material
Chrome alloy steel with uniform carbide distribution and
fine grain size in the matrix is used as raw material
for all of our bearing balls.
