Description: 1. Product material: bearing steel GCr15 (chemical composition: GC15 refers to a kind of high carbon chromium bearing steel with less alloy content, after quenching and low temperature tempering, it has high hardness, uniform structure and good wear resistance , High contact fatigue performance.) 2. Product attributes: G25 bearing steel ball, high-precision bearing steel ball, bearing steel ball 3. Production process: stamping, annealing, hard grinding, fine grinding and other multiple processes 4. Surface treatment: polishing, demagnetization, fine grinding 6. Product advantages: smooth and flat surface, high strength and wear resistance, super toughness 7. Product features:

1) Bearing steel ball characteristics: good wear resistance, hardness can reach 60-62 (HRC), solid compression; 2. The bearing steel ball is a solid steel ball, which is tough, super-precision wear-resistant, oily packaging, mirror brightness, The material has good abrasion resistance and is processed into finished steel balls with high precision. Bearing steel balls can be used for welding;

2) Nine processes of delicate polishing: stretching, cold forging, light ball, soft ball, heat treatment, hardening, fine grinding, sorting, packaging;

3) High-quality materials: using high-quality materials, exquisite workmanship, quality assurance, suitable for many purposes;

4) Exquisite craftsmanship: After several processes of stamping, annealing, thickening, anti-extrusion testing, durable;

5) Solid compression: The bearing steel ball is a solid steel ball with strong compression resistance; at the same time, it has good toughness, not easy to break, high hardness and high precision, and is suitable for precision instruments and machinery

6) The bearing is working to withstand the extreme pressure and friction, so the bearing steel is required to have high and uniform hardness and wear resistance, and high elastic limit. The requirements for the uniformity of the chemical composition of the bearing steel, the content and distribution of non-metallic impurities, and the distribution of carbides are very strict; 8. Scope of application: motors, aerospace, civil automobiles, CNC machine tools, mechanical engineering, bicycles, motorcycles, ships and yachts, etc. 9.
