In the global industrial supply chain, steel balls play a crucial role in various applications from precision machinery to heavy-duty equipment. For international buyers seeking reliable wear-resistant steel ball solutions, Changzhou Feige Steel Ball Co., Ltd. stands as a premier choice among Chinese manufacturers. As a national high-tech enterprise with 18,000㎡ production facilities and 4,000 tons annual capacity, we specialize in manufacturing high-precision steel balls that meet diverse industrial requirements worldwide.
Comprehensive Manufacturing Capabilities
Our core strength lies in our vertically integrated production system covering the entire manufacturing process from raw material selection to final product inspection. The factory operates two dedicated production zones equipped with advanced CNC grinding machines, lapping machines, and precision inspection equipment imported from Germany and Japan. This enables us to maintain consistent quality across all product lines while achieving production efficiency that supports our 4,000 tons annual output capacity.
The production workflow follows strict ISO-standardized procedures: raw material testing → cold heading forming → heat treatment → rough grinding → fine grinding/lapping → final inspection → anti-corrosion treatment → packaging. Each step incorporates multiple quality checkpoints to ensure product compliance with international standards including ISO 9001, IATF 16949, ISO 14001, and ISO 45001 certifications. Our quality control system implements statistical process control (SPC) methods and uses advanced measuring instruments like roundness testers and surface roughness meters to guarantee dimensional accuracy within ±0.001mm for critical parameters.
Product Range & Customization Options
As a full-service manufacturer, we offer an extensive product portfolio covering all standard and specialty steel ball requirements:
- Material Types: Chrome steel (GCr15), stainless steel (304/316/440C), carbon steel, brass, and custom alloy compositions
- Precision Grades: Complete coverage from G3 (general industrial) to G2000 (ultra-precision) standards
- Size Range: 0.3mm to 100mm diameter, with special capability for micro balls below 1mm

FAQ
What makes your steel balls suitable for high-wear applications?
Our wear-resistant steel balls undergo specialized heat treatment processes that achieve hardness levels between HRC 58-65, combined with precision grinding to maintain surface roughness below Ra 0.01μm. The material selection process prioritizes chrome steel (GCr15) and stainless steel (440C) with high carbon content, while our proprietary surface coating technology can further enhance wear resistance by 3-5 times compared to standard products.
How do you ensure quality consistency across large production batches?
We implement statistical process control (SPC) throughout manufacturing, with real-time monitoring of critical parameters like roundness, surface finish, and hardness. Each production line uses automated sorting equipment that rejects any balls deviating beyond ±0.001mm from specified dimensions. Our quality management system is certified to IATF 16949 automotive industry standards, requiring 100% inspection of key characteristics for every batch.
What is your minimum order quantity for custom steel balls?
Unlike many manufacturers with high MOQ requirements, we accept orders starting from 1kg (approximately 5,000-10,000 pieces depending on diameter) for standard sizes. For fully custom specifications involving non-standard materials or shapes, the minimum order typically ranges from 100kg to 500kg based on production complexity. We maintain dedicated small-batch production lines to support R&D projects and prototype development.
How do you handle urgent orders requiring short delivery times?
Our production system maintains 15% spare capacity at all times to accommodate urgent orders. For standard products in common sizes, we can typically ship within 3-5 working days after order confirmation. Custom orders usually require 2-4 weeks depending on specification complexity, but we offer expedited processing for priority clients through our VIP service channel. All shipments use premium logistics providers with real-time tracking updates.
What warranty do you provide for your steel balls?
We offer a 24-month quality warranty covering all manufacturing defects. During this period, any product failing due to material or workmanship issues will be replaced free of charge. Our after-sales team provides 24/7 technical support in multiple languages, with average response time under 2 hours for urgent inquiries. For large-volume clients, we assign dedicated account managers to handle all service requests directly.
