Under normal circumstances, the size of the miniature bearing is below 3.175mm. Risheng steel balls are currently the smallest and can produce miniature steel balls with a diameter of 0.5mm. The accuracy reaches G10 level or even G5 level. The miniature steel balls used for miniature bearings are generally 0.8mm, 1.0mm, 1.5mm, 1.588mm, 2.0mm, 2.381mm in diameter.
So what is the role of micro steel balls? Miniature steel balls play an important auxiliary role in miniature bearings.
The Carbon Steel Ball roundness and surface finish of the miniature steel ball affect the noise value of the miniature bearing. If there are strict noise value standards for bearings, G5 grade steel balls can be used. Generally speaking, most of the miniature steel balls we use for miniature bearings are G10 grade steel balls.
