Main characteristics of chrome bearing steel balls

- Dec 18, 2018-

Because in practical applications, bearings need to withstand great working pressure and friction, chrome bearing steel balls are required to have high and uniform hardness and wear resistance, as well as high elastic limit. The uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides are very strict. The bearing steel is also called high-carbon chromium steel, the carbon-containing Wc is about 1%, and the chromium Wcr is from 0.5% to 1.65%.

The hardness of the chrome bearing steel balls is high, and the material has good wear resistance. After cold working into a steel ball, the precision can reach one ten-thousandth of a millimeter, and the surface has a mirror effect. The color is chrome, but it cannot be soldered. The product has strong anti-corrosion, not easy to slip, high hardness, strong wear resistance, low roughness, and will not wear the ball seat.

For the time being, chrome bearing steel  balls are mainly used to assemble high-speed low-noise bearings to meet the high nutritional requirements of bicycles, motorcycles, automobiles, rails, universal ball, luggage, electronics industry, and can also be used to grind other media. .
