Introduction
GCr15SiMn bearing steel has higher wear resistance and hardenability than GCr15, medium cold working plastic deformation, poor weldability, sensitive to white spot formation, and temper brittleness during heat treatment.
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. It is mainly used to manufacture bearing rings with wall thickness> 12mm and outer diameter> 280mm. Ball diameter> 50mm; cone, cylindrical and spherical roller diameter> 22mm and needle rollers of all sizes.
The bearing steel adopts low temperature tempering. Temperature: 150~250 degrees. Under the premise of maintaining high hardness and high wear resistance, the internal stress and brittleness can be reduced to avoid cracking or premature damage during use.
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.
Application
Our steel balls can be used in many industrial fields, such as rolling media, ball bearings, vibration polishing, linear motion components, check valves and locking structures.

The High Quality Chrome Steel Balls are mainly applied in slewing ring bearing for wind turbines,such as single/double row ball bearing,single cross roller bearing,three roller bearing, double row angular contact ball bearing. and angular contact ball bearings, thrust ball bearings, wheel hub bearings, linear bearings and so on. |
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.
