Product Range: Comprehensive Solutions for Diverse Applications
Our core product offerings include two main categories: bearing steel balls and stainless steel balls, each available in a complete range of precision grades and sizes to meet virtually any industrial requirement. The precision grades we offer span the entire G3-G2000 spectrum, while our size range covers 0.3mm to 100mm diameters, making us one of the few manufacturers capable of supplying such comprehensive specifications.
Standard Product Specifications
Our standard product line includes:
- Bearing Steel Balls: Made from high-carbon chromium steel (GCr15), these balls exhibit excellent hardness, wear resistance, and fatigue life, making them ideal for precision bearings and mechanical components.
- Stainless Steel Balls: Available in grades 304/304L and 316/316L, these corrosion-resistant balls are perfect for applications in chemical processing, food processing, medical equipment, and marine environments.
- Carbon Steel Balls: Offering good mechanical properties at lower cost, these balls find applications in valves, locks, and other general industrial uses.
For each material type, we maintain strict control over chemical composition and heat treatment processes to ensure consistent quality across all production batches. Our in-house testing laboratory is equipped with advanced instruments for material analysis, dimensional measurement, and surface inspection.
Customization Capabilities: Beyond Standard Solutions
Understanding that many industrial applications require specialized solutions, we offer comprehensive customization services that set us apart from standard manufacturers. Our non-standard customization capabilities include:
| Customization Aspect | Available Options |
|---|---|
| Material Composition | Special alloy steels, brass, aluminum, ceramic, plastic, and other materials upon request |
| Surface Treatments | Polishing, grinding, passivation, plating (nickel, chrome, zinc), blackening, and other coatings |
| Precision Grades | Custom grades beyond standard G3-G2000 range based on specific application requirements |
| Special Shapes | Flat balls, satellite balls, cylindrical rollers, conical shapes, and other custom geometries |
| Tolerances | Tighter tolerances than standard specifications for ultra-precision applications |
Our engineering team works closely with clients during the customization process, from initial design consultation to prototype development and final production. This collaborative approach ensures that the final product perfectly matches the application requirements while maintaining cost-effectiveness.
