Ball Precision Bearings 1mm - 20mm Loose Bike Bicycle Cycle Hub Cone Machinery. This carbon steel ball is a high-precision carbon steel ball, long service life.

High carbon chromium bearing steel; chromium-bearing steel with chromium as a major component. With a carbon concentration of around 1% and a chromium percentage of about 1.5%, Gcr15 produces the most bearing steel in the world, making up over 80% of the total production. As the majority of bearing parts must be pressure formed to fulfill the G5-G40 standard (the smaller the number, the higher the precision), rolling bearing steel balls demand high dimensional accuracy of steel. Application: Bearing steel balls are widely used in high-speed and low noise bearings, bicycles, motorcycles, automobiles, slide rails, universal balls, luggage, electronic industries, and can also be used to grind other media.
