    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
