The surface hardness reaches HRC62-65, and the hardness uniformity is ≤ 3HRC.Can adapt to environments ranging from -40 ℃ to 200 ℃, maintaining stable performance even under acidic and alkaline concentrations ≤ 5%, with a service life of over 8000 hours, and no cracks or deformations after 500 drop hammer impact tests.Accurate roundness, low running resistance, no risk of ball breakage or blockage, with a service life more than 2.5 times that of competitors. The average annual replacement frequency is reduced by 60%, and downtime maintenance time is reduced (saving 40-60 hours per year).Changzhou Feige Steel Ball Co.,Ltd With 36 years of experience in ball manufacturing, we excel not only in steel balls (low-sulfur phosphorus bearing steel balls:hardness up to HRC62-65, service life over 8000 hours; ordinary carbon steel balls: daily output 200,000+ pieces) but also realize standardized production of full-category balls: * Copper balls: High-conductivity type (conductivity ≥98% ), wear-resistant type for mine grinding; * Glass balls: Precision type (roundness error ≤0.003mm ), high-transparency type (transmittance 92%+ ); * Ceramic balls: High-hardness type (hardness ≥HRA88 ), corrosion-resistant type (withstands 200℃ high temperature). Covering scenarios from industrial grinding to precision instrument matching, we provide one-stop solutions. With a stable quality pass rate of 99.8%, you don't need to compare prices across factories—enjoy unified delivery efficiency and quality assurance. Changzhou Feige Steel Ball Co.,Ltd was founded in 1989, it's a professional manufacturer dedicated in pro-ducing precision steel ball. The company is IS0 9001 and lATF 16949 certified. lt covers an area of 18,000 square meters includingoffice, workshop, warehouse and laboratory. The sophisticated laboratory equipped with precised, worldwiderespected machines and is managed by properly trained and qualified personnel. Feige still continues toinvest in equipment to measure and insure that specifications for roundness, surface, diameter and hardnessare achieved. The factory mainly produce chrome steel ball and stainless steel ball in accordance with international stan-dard. Besides, it's extremely flexible and can accommodate orders for non-standard ball sizes and diversematerials such as copper and ceramic. The Monthly production capacity is around 300 tons. These balls arewidely used in precision bearings, bicycle and automotive components, sliding rails, recirculating ball screws,pumps,sprayers, milling machines.F A Q1.
