Bearings Balls
We, at Shreeji Balls, have been manufacturing bearing balls since our inception. Now, the production lines in our plants 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 and surface quality, so that, when used in ball bearings, they demonstrate an extremely low level of running noise.
Raw material also plays a very important role. The dynamical properties of the chrome alloysteel 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.
Material: Chrome alloy steel with uniform carbide distribution and fine grain size in the matrix is used as raw material for all of our chrome alloy steel balls.
