I used to be a salesman for a large industrial distributor. Over the years I have accumulated a large quantity of Chrome Bearing Balls in vast array of sizes, in both inch and metric sizes. All are NEW and never used. They are made of AISI 52100 Chrome Alloy Steel. Almost all are Grade 25.
I also have STAINLESS STEEL balls.
Prices are well below anything on ebay or anyplace else I've found on the internet.
I can ship these via the US Postal Service if you want to save some gas.
Let me know what SIZE and quantity you are looking for. I will promptly email you the price.
Below are the sizes I have. I will update them as they sell.
