Quoted from blownfuse:I just looked at the last box I have, no part numbers. All it says on the box is, size 1 1/16", quantity 25, AFBMA GRADE (can't make out the grade # but I bought the highest quality they had), 440C STAINLESS STEEL. I don't know what the price is on them now but 8 years ago, they were about $6.00 each. Like I said, expensive. However, I've never had to replace any of them (just buff them occasionally) since they've been installed so in that respect, they've been cheap. They're made to hold up under a lot of pressure in precision machines so I thought they'd work great in my games. I'll try to get a part number when I order more this time.

Very cool idea. Doing a quick ebay search, I found these: ebay.com link: 100 1 1 16 Inch G25 Precision Chromium Chrome Steel Bearing Balls AISI 52100
Any opinion on them?
