In the global industrial supply chain, stainless steel balls play a critical role in applications ranging from precision instruments to heavy machinery. As a specialized manufacturer, Changzhou Feige Steel Ball Co., Ltd. has established itself as a benchmark in the industry through technical innovation, quality assurance, and customized solutions. This article explores the company’s capabilities, product range, and service advantages that make it a preferred partner for international clients.

Company Overview: A Foundation of Scale and Certification
With a total production area of 18,000 square meters split between a main factory and subsidiary plant, Feige Steel Ball operates at an annual capacity of 4,000 metric tons – positioning it among China’s top three producers by volume. The company’s “Saige” brand has gained international recognition through consistent delivery of high-performance products across 30+ countries.
Four critical certifications underpin the company’s quality commitment:
- ISO 9001: Quality management system
- IATF 16949: Automotive industry standards
- ISO 14001: Environmental management
- ISO 45001: Occupational health and safety
These accreditations enable Feige to serve clients in regulated sectors including automotive, aerospace, and medical devices while maintaining compliance with international trade requirements.
Product Range: Precision Across All Dimensions
The company’s core product lines address both standard and specialized needs through two material categories:
1. Bearing Steel Balls
Engineered for high-load applications, these balls feature:
- Hardness: HRC 60-66
- Surface finish: Ra ≤ 0.01μm
- Grade range: G3-G1000
- Applications: Automotive transmissions, wind turbines, mining equipment
2. Stainless Steel Balls
Designed for corrosion-resistant environments, these products offer:
- Material grades: 304, 316, 440C, 420
- Grade range: G10-G2000
- Special treatments: Passivation, electro-polishing, black oxide coating
- Applications: Food processing machinery, chemical equipment, marine components

Dimensional Capabilities
Feige’s production flexibility accommodates:
- Diameter range: 0.3mm (micro-balls) to 100mm (large balls)
- Tolerances: ±0.001mm for ultra-precision grades
- Batch sizes: 1,000 pcs to 10 million pcs per order
Customization: Engineering Solutions for Specialized Needs
Beyond standard products, the company specializes in non-standard solutions through:
1. Material Engineering
Clients can specify custom alloys with adjusted carbon content, chromium ratios, or molybdenum additions to achieve specific mechanical properties. For example, a European automotive supplier collaborated on a 440C variant with enhanced impact resistance for shock absorber components.
2. Geometric Modifications
The in-house CNC machining center produces:
- Flat-ended balls for valve applications
- Hollow balls for lightweight structures
- Drilled balls for fluid passage systems
- Satellite balls for planetary gear systems
3. Surface Enhancements
Advanced treatments improve performance in specific environments:
| Treatment Type | Benefit | Typical Application |
|---|---|---|
| Electro-polishing | Reduces surface roughness by 50% | Pharmaceutical equipment |
| Black oxide coating | Prevents galvanic corrosion | Marine hardware |
| Teflon coating | Reduces friction coefficient by 30% | Textile machinery |
Export Services: Streamlining Global Supply Chains
Feige provides end-to-end export support through:
- Compliance Documentation: REACH, RoHS, Conflict Minerals reports
- Packaging Solutions: Vacuum-sealed plastic tubes, rust-proof cartons, wooden crates
- Logistics Coordination: FCL/LCL shipping, air freight, DDP/DDU terms
- Customs Clearance: HS code classification, duty optimization advice
A recent case involved a Middle Eastern client requiring 50,000 pcs of G100 316 stainless steel balls (6mm) with electro-polishing. Feige completed production in 12 days, arranged air freight, and delivered the cargo to the client’s warehouse in 18 days total – beating the competitor’s quoted lead time by 40%.
FAQ
What is the minimum order quantity for customized stainless steel balls?
Our MOQ starts at 1,000 pieces for standard dimensions and 5,000 pieces for customized specifications. Smaller trial orders may be accepted for new clients after technical evaluation.
How do you ensure dimensional consistency across large batches?
We implement three-level quality control: 1) Incoming material inspection using spectrometers, 2) In-process monitoring with laser micrometers, and 3) Final inspection via random sampling per ISO 3290 standards.
What lead time should I expect for a first-time order?
Standard products ship within 7-10 days. Custom orders require 15-25 days depending on complexity, with tooling preparation accounting for 5-7 days of that period.
Do you provide material certificates with each shipment?
Yes, every delivery includes Mill Test Certificates (MTC) from our steel suppliers and in-house inspection reports traceable to specific production batches.
How does your after-sales service work for defective products?
We maintain a 24-month warranty period. Clients must submit photographic evidence of defects within 30 days of discovery. After verification, we offer free replacements or credit notes within 5 working days.
