In the global industrial manufacturing landscape, the demand for high-quality, corrosion-resistant steel balls continues to grow across diverse sectors. As a premier manufacturer based in Changzhou, China, Changzhou Feige Steel Ball Co., Ltd. has established itself as a trusted partner for businesses worldwide seeking customized steel ball solutions that meet stringent quality standards and application requirements.
With over 18,000 square meters of production facilities and an annual capacity of 4,000 metric tons, our company stands among China’s top-tier steel ball producers. As a national high-tech enterprise recognized by both national and international standards, we maintain four critical certifications: ISO9001, IATF16949, ISO14001, and ISO45001. These certifications underscore our commitment to quality management, environmental responsibility, and workplace safety throughout our manufacturing processes.

Comprehensive Product Range for Diverse Applications
Our core product portfolio includes both bearing steel balls and stainless steel balls, manufactured to precision grades ranging from G3 to G2000. This comprehensive gradient coverage ensures we can supply components for applications requiring extreme precision (G3-G10) as well as those needing more economical solutions (G1000-G2000). The size spectrum spans from 0.3mm micro balls up to 100mm large balls, accommodating virtually any industrial requirement.
What truly sets us apart is our custom manufacturing capability. We understand that standard products often cannot meet the unique demands of specialized applications. Therefore, we offer complete customization across multiple parameters:
- Material composition: We can create specific alloys or use alternative base materials based on your corrosion resistance requirements
- Surface treatments: From standard passivation to specialized coatings like black oxide, nickel plating, or Teflon coating
- Tolerance precision: We achieve tolerances as tight as ±0.001mm for ultra-precise applications
- Special shapes: Beyond standard spheres, we produce balls with flat spots, grooves, holes, or other custom geometries
This flexibility makes our steel balls suitable for an extensive range of industries including automotive components, aerospace systems, medical devices, food processing equipment, chemical processing machinery, and marine applications where corrosion resistance is paramount.
Advanced Manufacturing Capabilities
Our production process combines state-of-the-art equipment with rigorous quality control at every stage. The manufacturing journey begins with careful material selection, followed by precision cold heading to form the basic ball shape. We then employ advanced grinding and lapping techniques to achieve the required surface finish and dimensional accuracy.
For corrosion-resistant applications, we implement specialized processes including:
- Stainless steel vacuum melting to eliminate impurities that could reduce corrosion resistance
- Controlled atmosphere heat treatment to enhance material properties without introducing surface contamination
- Electropolishing for ultra-smooth surfaces that resist chemical attack
- Advanced passivation techniques to maximize the protective oxide layer on stainless steels

Quality Assurance System
Our four-tier certification system ensures consistent quality across all production batches. Each ball undergoes multiple inspection stages including:
| Inspection Stage | Method | Acceptance Criteria |
|---|---|---|
| Raw Material | Spectral analysis, hardness testing | Meets AISI/ASTM standards |
| In-process | Dimensional measurement, surface inspection | Within specified tolerances |
| Final Inspection | 100% visual inspection, random sampling for lab tests | Zero defects in visual inspection, meets all specs in lab tests |
| Packaging | Weight verification, condition check | Matches order specifications |
Export Services and Global Support
As an established export-oriented manufacturer, we provide comprehensive services to simplify international procurement:
Documentation: We generate all necessary export documents including certificates of origin, quality certificates, material test reports, and packing lists in compliance with international trade regulations.
Packaging Solutions: Our packaging options range from standard plastic tubes to custom wooden crates designed to protect balls during long-distance transportation. We can also implement special labeling requirements or barcode systems for inventory management.
Logistics Coordination: For customers without in-house logistics departments, we offer complete shipping coordination including freight booking, customs clearance assistance, and door-to-door delivery options.
After-Sales Support: Our commitment doesn’t end with delivery. We maintain detailed production records for every batch, enabling quick resolution of any quality concerns. Our 24/7 technical support team assists with application questions, and we offer free replacement for any products failing to meet specifications.
FAQ
What makes your steel balls corrosion-resistant?
Our corrosion resistance comes from multiple factors: material selection (primarily stainless steel grades like 304, 316, 440C), specialized manufacturing processes that minimize surface contamination, and optional protective coatings. For marine or chemical applications, we recommend specific grades and treatments based on the expected exposure conditions.
Can you match existing samples for replacement parts?
Absolutely. We have extensive experience in reverse engineering components. Simply send us your sample and we’ll analyze its material composition, dimensions, surface finish, and other critical parameters to create an exact match or improved version.
What is your minimum order quantity for custom products?
Our MOQ varies based on product complexity. For standard sizes, we can accommodate orders as small as 10,000 pieces. For fully custom designs, we typically require a minimum of 50,000 pieces to justify the setup costs, though we evaluate each request individually.
How do you ensure consistent quality across large orders?
Quality consistency is maintained through several systems: 1) Using the same raw material batch for entire orders when possible, 2) Employing automated production equipment with minimal operator intervention, 3) Implementing statistical process control (SPC) at critical stages, and 4) Conducting final inspections on 100% of products.
What certifications do your products carry?
All our products comply with our ISO9001 quality management system. For automotive applications, we also meet IATF16949 requirements. We can provide material certificates showing compliance with AISI/ASTM standards, and for food-grade applications, we offer certifications proving compliance with relevant regulations.
How long does production typically take?
Standard products from our inventory can ship within 5-7 days. For custom orders, lead time depends on complexity: simple size variations may take 2-3 weeks, while fully custom designs with new tooling might require 6-8 weeks. We always provide accurate delivery estimates before order confirmation.
Do you offer sample testing before full production?
Yes, we encourage sample testing for new customers or complex applications. We can provide free samples of standard products or produce prototypes of custom designs for a nominal fee that’s credited toward future orders.
What payment terms do you accept?
For first-time customers, we typically require 30% deposit with balance before shipment. For established relationships, we offer flexible terms including letters of credit and open account options. We accept major currencies and work with all standard international payment methods.
How do you handle product liability issues?
We maintain comprehensive product liability insurance covering up to $5 million per incident. Additionally, our quality management system includes traceability for every production batch, enabling rapid investigation and resolution of any potential issues.
Can you assist with product selection for specific applications?
Our technical team has extensive experience across industries. We provide free application consulting to help you select the optimal material, grade, and surface treatment based on your operating conditions, load requirements, and environmental factors.
