    are pinballs really balls of steel or just aluminum? if they were real balls of steel do you think it would be hard to hit the ramps or may do damage to the plastics?

    Says the Anti-Friction Bearing Manufacturers Association (AFBMA) has a set of grades for bearing balls. A grade three ball has to be spherical within 3 millionths of an inch and the diameter must be accurate within 30 millionths of an inch. This means that for a grade three quarter-inch ball, the diameter would have to be between 0.24997 and 0.25003 of an inch and the smallest diameter measured on the ball has to be within 3 millionths of the largest diameter.

    Does anyone know the grade of Pinball Balls of Steel?
    I want to make sure mine are round enough. plain and simple.

    Grade 100 carbon steel.

    Grade 100? no wonder why I have so many stwange air bawls. I need rounder ones (more spherical). gimme the sphericallist balls you got! This is bull crap!

    #15 3 years ago

    They look round to me.

    I swear I have lost some HUGE pinball matches due to uneven balls that aren't even Carbon Steel.
    I will have to bring my scale next time, weight the balls and do some density math before the tourney starts.
    I want to make sure they are within IFPA specifications for touwrnaments.

    "Balls of steel" was the best pinball game on P.C back in the day. Played it for years thinking, man it would be cool to own a pinball one day.
