Bearing as generally made using a skew rolling technique or by upsetting. A round rod or wire is fed into the roll gap and the rotating rolls form spherical blanks continuously.
The upsetting method involves taking a small piece of round bar and squashing it into a ball shape using two hemispherical dies. After the ball is initially made it is then ground and polished.
Good Luck
