How are steel balls manufactured

Materials :

Most are of stainless or carbon steel, while the rest are from brass, aluminum, chrome steel, precious metals, and offers glass and plastic.

Steps in Steel Ball Manufacturing Process


In the first step, heading machines cut wire into short lengths and form it into spherical shapes between dies.

ball bearing production process


The flash line, a ridge left by the forming dies, is removed as balls roll between heavy, cast iron plates.

Soft Grinding:

Similar to deflashing, except that a grinding stone is used to improve precision.


Carbon steel balls are next carburized and hardened. Heat treatment imparts the desired hardness and case depth.

This step removes the residues and by-products from the heat-treating process.

Hard Grinding:How are steel balls manufactured

Slow, meticulous grinding assures proper sizing and sphericity, with tolerances as close as ±.0001″.

Several proprietary lapping processes can bring balls to the requirements of ISO 3290 Grade 10 – 48.


Proprietary chemical and mechanical processes give the balls their final micro-smoothed finish, for increased wear resistance and product longevity.


All products pass through at least two 100% inspection stages, using proprietary, automated inspection processes.
