When it comes to high-performance industrial components, high carbon chromium bearing steel stands out as a critical material for manufacturing precision steel balls used in bearings, automotive parts, and heavy machinery. As a global supplier of industrial steel solutions, Changzhou Feige Steel Ball Co., Ltd. has established itself as a professional manufacturer specializing in high carbon chromium bearing steel production, with an annual capacity of 4,000 tons and a comprehensive range of precision grades from G3 to G2000.
Why Choose High Carbon Chromium Bearing Steel?
High carbon chromium bearing steel, also known as 100Cr6 or SUJ2, represents the gold standard for bearing applications due to its exceptional combination of hardness, wear resistance, and fatigue strength. This material contains approximately 1% carbon and 1.5% chromium, which forms hard carbide particles during heat treatment that significantly enhance the steel’s durability under heavy loads and high-speed operations.
The manufacturing process for high carbon chromium bearing steel balls at Changzhou Feige involves precise control at every stage: from raw material selection to cold heading, grinding, lapping, and final inspection. Our state-of-the-art production facilities in Changzhou, covering 18,000 square meters across main and branch factories, enable us to maintain consistent quality while offering full-spectrum sizes from 0.3mm micro balls to 100mm large balls.
Comprehensive Product Range & Customization Capabilities
As a full-service manufacturer, we understand that different industrial applications demand specific material properties and dimensional tolerances. Our product portfolio includes:

FAQ
What makes high carbon chromium bearing steel superior for industrial applications?
The combination of approximately 1% carbon and 1.5% chromium creates hard carbide particles during heat treatment that provide exceptional wear resistance, fatigue strength, and dimensional stability under heavy loads and high-speed operations, making it ideal for demanding industrial environments.
How does Changzhou Feige ensure product quality consistency?
We implement strict quality control at every production stage, from raw material inspection using spectrometers to final product testing with advanced measurement equipment. Our four international certifications (ISO 9001, IATF 16949, ISO 14001, ISO 45001) guarantee adherence to global standards.
Can you produce steel balls with non-standard dimensions or materials?
Absolutely. Our custom manufacturing capabilities include special sizes outside standard ranges, alternative material compositions (such as different chromium or carbon percentages), and unique surface treatments like black oxide coating or passivation for specific applications.
What is your minimum order quantity for custom steel balls?
While our standard products have flexible ordering options, custom solutions typically require a minimum order quantity (MOQ) that depends on the complexity of specifications. Our sales team works with each client to determine feasible production batches that balance cost efficiency with project requirements.
How do you handle international shipping and customs clearance?
We provide full export services including professional packaging, preparation of all necessary compliance documents (certificates of origin, quality reports, etc.), and coordination with freight forwarders for seamless door-to-door delivery. Our experienced logistics team ensures smooth customs clearance in destination countries.
What warranty do you offer on your steel balls?
All products come with a quality guarantee covering manufacturing defects. We offer free replacements for any items failing to meet specified tolerances or material properties. Additionally, our lifetime process consultation service provides ongoing technical support for clients using our steel balls in their applications.
How quickly can you deliver standard products?
For in-stock items, we typically prepare shipments within 5-7 working days after order confirmation. Custom products require additional production time, which varies based on specifications but generally ranges from 2-4 weeks. Our sales representatives provide precise lead time estimates during quotation.
Do you provide samples before bulk orders?
Yes, we offer sample services for clients to evaluate product quality before placing larger orders. Sample quantities and delivery times depend on availability and customization requirements, with our team working to fulfill sample requests as efficiently as possible.
