The company has passed the four international certifications of ISO9001, IATF16949, ISO14001, and ISO45001, covering quality management system, automotive industry quality standards, environmental management system, and occupational health and safety management system, ensuring full-process control from raw material procurement to finished product delivery. Its core product, the "Pigeon" brand steel ball, is renowned for its high precision and wear resistance, widely used in automotive bearings, precision instruments, aerospace, and other fields, becoming an important force in the export of high-end steel balls in China.

Technical Layout: Research and production of high-end steel balls across all categories
Feige steel ball's technical layout covers a full range of products including stainless steel balls, carbon steel balls, and alloy steel balls, with the customization technology for stainless steel balls particularly outstanding. The company employs advanced cold heading forming technology, directly processing wire rods into blanks through multiple cold heading machines, reducing material waste and enhancing the density of the balls; coupled with high-precision grinding equipment, it can control the ball roundness within 0.001mm and achieve a surface roughness of Ra0.01μm, meeting the stringent requirements of high-precision bearings. In addition, the company's independently developed vacuum heat treatment technology, through precise control of heating temperature and holding time, eliminates internal stress in the balls, significantly improving their fatigue resistance and extending service life by over 30%.
Application Experience: Full-scenario coverage from automotive bearings to precision instruments
In the automotive field, FeiGe steel balls supply matching ball bearings to many well-known car manufacturers, with their products passing the IATF16949 certification and featuring high-speed rotation and low noise. For instance, the FeiGe steel balls used by a certain new energy vehicle brand have a bearing vibration value below 0.5mm/s at a speed of 120km/h, significantly better than the industry average. In the field of precision instruments, FeiGe steel balls have customized micro stainless steel balls for a medical equipment company, with a diameter of only 2mm yet capable of withstanding a static load of 500N, ensuring stable operation of the equipment under high-frequency vibration conditions. These cases fully demonstrate the advantages of FeiGe steel balls in terms of technical adaptability and scenario-based solutions.

FAQ: Common Issues in Customized Stainless Steel Ball Technology Explanation
Q1: How to determine the precision standard for custom stainless steel balls?
A1: Precision standards should be determined based on the application scenario. For example, steel balls for automotive bearings usually require G10 grade (roundness ≤ 0.001mm), while precision instruments may require G5 grade (roundness ≤ 0.0005mm). Feige steel balls can provide a full range of precision grades from G40 to G5 according to customer requirements.
Q2: How to select the material for stainless steel balls?
A2: Material selection should consider corrosion resistance, hardness, and cost. 304 stainless steel is suitable for general corrosion environments, 316 stainless steel has stronger resistance to seawater corrosion, and 440C stainless steel can reach a hardness of HRC58, suitable for high-wear scenarios. Feige steel ball provides material inspection reports to ensure that the composition meets the ASTM A276 standard.
Q3: What is the customization period and minimum order quantity?
A3: Standard size steel ball customization takes 15-20 days, while special sizes or materials require more than 30 days. The minimum order quantity varies by specification, with steel balls below 5mm diameter requiring 5,000 pieces and those above 10mm diameter requiring 2,000 pieces. Feige steel balls support small batch trial production to reduce customer risk.
