7/8" Inch Chrome Steel Ball Bearings G25-10 Bearings

I purchased this for use in a baseball pitch and bat pinball machine (1957 Williams Baseball) that uses non-standard pinballs. This is also the typical size that are used in the tilt sensor in the cabinet. This size is not as easy to obtain as the regular sized pinballs.These look great and work perfectly.
