factory price 2mm 5mm 3mm precision bearing ball chrome steel ball
Product Description
Chrome steel balls are also known as high-carbon chromium alloy steel balls. Our factory mainly selects GCr15 raw materials from large steel plants for production in strict accordance with the national standard GB/T308.1-2013. GCr15 is the domestic name, the American standard is AISI52100, the Japanese standard is SUJ2, and the German standard is 100Cr6/1.3506, all of which are a kind of material.
This material has high hardness, tensile strength, contact fatigue strength and wear resistance, and considerable toughness, which meets the requirements for corrosion resistance and high temperature resistance under certain conditions. Bearing steel ball is one of the important parts of ball bearings. The quality of the bearing has a great influence on the dynamic performance and service life of the bearing. The reduction of bearing vibration value and the increase of service life and the improvement of the surface quality of the bearing steel ball Inseparable.

Application
Chrome steel balls are used as rolling elements in ball bearings to carry and transfer loads. Because the steel ball works under bad hand conditions, it is easy to cause fatigue damage. A large number of experiments have proved that in the fatigue-damaged bearings, more than 60% of the bearings are scrapped due to the first failure of the steel ball. At the same time, steel balls are the most critical parts in low-vibration and low-noise bearings. Therefore, choosing high-quality chrome steel balls is the key to ensuring bearing quality and life. In Ball Bearings,Grade 20, hardened chrome steel balls are applicable. Manufactured in high carbon high chrome steel, also called bearing steel (AISI-52100 / EN-31)
Ball Diameter Tolerance: 0.000020 inch or 0.0005 mm or 0.50 microns.Basic Diameter Tolerance: ± 0.0001" or ± 0.0025 mm or ± 2.50 microns
Meanwhile, chrome steel balls are also widely used in ball valve, ball screw, aviation, auto parts, wind power generation, ball pen and home appliance.
