Are you refering to the roller bearing or the technology that enables the ball point pen to work? The roller bearing is a sphere that sits in a cone allowing smooth movement and a uniform means of distributing the ink within the pen.

Older metallic ball tips were machined by grinding them into a sphere

Powder Metallurgy process is employed to manufacture the current cemented carbide ballpoint tips

for more info google
"ballpoint pen" +grinding
&
"ballpoint pen" +"powder metallurgy"
