59.95mm(2.360236"),59.94mm To 60.06mm, High Chrome Steel Balls
Introduction
The full name of bearing steel is rolling bearing steel. It has high compressive strength and anti-fatigue performance, high hardness, high wear resistance and certain toughness, good hardenability, and extremely strict control of sulfur and phosphorus. It is a high-grade high-quality steel.
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.
We mainly produce chromium steel with a size of 7-82.55mm. 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 precision bearings, automotive parts (brakes, steering systems, spools), bicycles, agitators, electrical appliances, sliders, quick connectors, machine tools, locking mechanisms, conveyor belts, pumps, casters, Measuring instruments, valves, etc.
Ideal applications for chrome balls include rolling media, ball bearings, vibration polishing, linear motion components, check valves and locking structures.
