In the global industrial manufacturing sector, the demand for high-quality bearing components continues to grow steadily. As a professional high carbon chromium bearing steel supplier and manufacturer, Changzhou Feige Steel Ball Co., Ltd. has established itself as a key player in the precision steel ball production industry. With 18,000 square meters of manufacturing space across main and subsidiary factories, our annual production capacity reaches 4,000 metric tons, placing us among China’s top steel ball producers.
Core Competencies in Bearing Steel Production
Our manufacturing expertise centers on two primary product lines: bearing steel balls and stainless steel balls. The bearing steel balls utilize high carbon chromium alloy (GCr15), renowned for its exceptional hardness (62-66 HRC), wear resistance, and fatigue life. These properties make our steel balls ideal for demanding applications in automotive, aerospace, and precision machinery industries.
The stainless steel ball production employs materials like 304, 316, and 440C grades, offering excellent corrosion resistance for applications in food processing, medical devices, and marine environments. Our comprehensive material selection ensures we can meet diverse customer requirements across various industrial sectors.
Precision Manufacturing Standards
As a certified ISO9001, IATF16949, ISO14001, and ISO45001 manufacturer, we maintain rigorous quality control throughout the production process. Our precision steel balls cover the complete G3-G2000 grade spectrum, with dimensional tolerances as tight as ±0.001mm for G3 grade products. This precision enables us to serve both micro-precision equipment manufacturers and heavy industrial machinery producers.
The production workflow incorporates advanced cold heading, grinding, lapping, and polishing technologies. Each steel ball undergoes multiple quality inspections using sophisticated equipment like roundness testers, surface roughness meters, and hardness testers. This comprehensive quality assurance system guarantees consistent product performance that meets or exceeds international standards.

FAQ
What makes high carbon chromium bearing steel suitable for precision applications?
High carbon chromium bearing steel (GCr15) contains approximately 1% carbon and 1.5% chromium, creating a martensitic structure after heat treatment. This composition provides exceptional hardness (62-66 HRC), excellent wear resistance, and good dimensional stability under load, making it ideal for precision bearing components that require long service life under high stress conditions.
How does your company ensure consistent product quality across large production volumes?
We implement a multi-layered quality control system that includes: 1) Raw material inspection before production, 2) In-process quality checks during each manufacturing stage, 3) Final product testing for dimensional accuracy, surface finish, and hardness, and 4) Random sampling for destructive testing. All inspection data is recorded in our ERP system for complete traceability.
What is the minimum order quantity for custom steel ball production?
Our MOQ varies based on product complexity and customization requirements. For standard size steel balls, we can accommodate orders as small as 10,000 pieces. For fully customized products involving special materials or processes, the MOQ typically starts at 50,000 pieces. We evaluate each custom request individually to provide optimal solutions.
How long does it take to produce non-standard steel balls?
Production lead time depends on several factors including product complexity, order quantity, and current production schedule. For simple modifications to standard products, lead times range from 15-25 days. For completely new designs requiring tooling development, the process typically takes 30-45 days from design approval to first article inspection.
What certifications do your steel balls comply with?
Our products meet multiple international standards including ISO 3290 (precision steel balls), ASTM F2999 (stainless steel balls), and DIN 5401 (ball bearing quality). The manufacturing facility maintains ISO9001 (quality management), IATF16949 (automotive quality), ISO14001 (environmental management), and ISO45001 (occupational health and safety) certifications, ensuring comprehensive compliance with global industry requirements.
