For other sizes of carbon steel balls or different types of steel (chrome steel, stainless steel) please view my other listings.  If the exact size is not critical the slightly smaller (12.0mm) may work out cheaper per ball - see https://www.ebay.co.uk/itm/175306348141

Please note: dimensions are approximate, there is some tolerance on these relatively inexpensive bearings.  A sample is measured to ensure they are nominally the size indicated - see picture of bearing in calipers.  Expect something in the order of +/-5% - if you require a precise size with no variation please purchase off a supplier that can guarantee this
