Abbott manufactures over five billion balls each year in a range of sizes and materials. Most are of stainless or carbon steel, while the rest are from brass, aluminum, chrome steel, precious metals, offers glass and plastic.

The balls are measured with very accurate machinery to determine if they meet the required tolerances. For instance, the Anti-Friction Bearing Manufacturers Association (AFBMA) has a set of grades for bearing balls. A grade three ball has to be spherical within 3 millionths of an inch and the diameter must be accurate within 30 millionths of

To make balls the easy way: Start with a rod of steel, and cut off little pieces slightly larger than the volume of the ball. Then progressively forge them slightly round with little dies, then roll them through 2 parallel plates, one of which ha

Precision balls are used in critical aeronautical bearings, guidance system balls for space and military applications, precision valves, automotive bearings and other applications where higher precision is necessary. Precision balls are defined by grade: The lower the number of the grade, the more precision to which the ball is manufactured.

Ball Screws. Ball screws are very similar to ball bearings in that they generally use either chrome steel or type 440C hard stainless steel. A peculiarity of ball screws is that they typically have a load ball and the next ball is a .001-inch undersized spacer ball, and so on.

Bearing balls are special highly spherical and smooth balls, most commonly used in ball bearings, but also used as components in things like freewheel mechanisms. The balls come in many different grades.These grades are defined by bodies such as the American Bearing Manufacturers Association (ABMA), a body which sets standards for the precision of bearing balls.

Bearings made from this material are generally more expensive than chrome steel bearings. Martensitic Stainless Steel Bearings– ACD34 / KS440 / X65Cr13 Many miniature bearing manufacturers make their rings and balls with a stainless steel material with slightly lower carbon and chromium content than AISI 440C known under several names including ACD34, KS440, and X65Cr13.

Who knows why steel balls were not machined, from the very beginning, to a principle similar to that of stone ball production. This production method guarantees for a large number of balls equal diameters when machined between two plates, since only the ball contacting the upper and lower rotating surface simultaneously with a certain load can be ground.

Steel ball bearings have been the standard bearings used in industrial electric motors for many years. When one particular product has been used for so long, we understand that it can be difficult for people to make the switch to something else, even if it may be a better product that offers superior performance.

Almost all parts of all ball bearings are made of steel. Since the bearing has to stand up to a lot of stress, it needs to be made of very strong steel. The standard industry classification for the steel in these bearings is 52100, which means that it has one percent chromium and one percent carbon (called alloys when added to the basic steel).
