Introduction
High-carbon chromium bearing steel is widely used worldwide. The most commonly used types are GCr15 and GCr15SiMn. The performance of the two steels is basically the same, but the hardenability of GCr15SiMn is better than GCr15, so for larger bearings parts should be made of GCr15SiMn steel. High-carbon chromium bearing steel is widely used to make rolling bearing rings and rolling parts.
GCr15 bearing steel is widely used in the manufacture of spindle bearings, railway bearings, engine bearings, machine tool bearings, mining machinery bearings, general machinery bearings, etc.
GCr15SiMn bearing steel is mainly used to manufacture thick-walled bearings, such as large and super large bearings, used in heavy machinery and rolling mill machinery.
On the basis of GCr15 steel, the content of Si and Mn is appropriately increased to improve its hardenability and elastic limit, and its wear resistance is also better than that of GCr15. The applicable size range for manufacturing rolling elements is larger than that of GCr15.
Mainly used in ball bearing design and various harsh industrial applications. Vacuum degassed AISI E52100 chrome steel is used to obtain high-quality balls with excellent surface finish, through hardness and high load capacity. Can also provide consumable electrode vacuum melting material.
We mainly produce chromium steel with a size of 7.9375mm to 82.55mm. The main material is high chromium GCR15 or GCR15SiMn.
The ball has high precision, good surface smoothness, standard hardness and excellent wear resistance. Our products have been widely exported to Europe, America, Japan, Korea etc.
The best precision, make your bearing roll smoother.

Properties and Advantage
[High-quality material] Made of high-quality chromium steel, high-grade bearing steel, corrosion resistance, high precision and high hardness. Polished surface, smooth without burrs, standard shape and high precision, completely round.
[Anti-rust] Corrosion resistance and high oxidation resistance. It is also suitable for humid environments. The surface is coated with a small amount of grease to improve lubrication and prevent corrosion and rust.
[Long use] The heat treatment process can make the bearing ball stronger and bear high pressure and wear resistance.
[Wide application] Widely used in wind turbine bearings, yaw bearing, slewingring bearing and so on.
