Casting Bronze Bearing Material Selection and Performance Optimization Guide

1. Principles of Selecting Bronze Bearing Materials

In the production of Casting Bronze Bearing, material selection is the core factor to ensure bearing performance. Zhejiang Shuangnuo Bearing Technology Co., Ltd. focuses on the research and production of self-lubricating copper alloy products, using centrifugal casting, continuous casting, and metal mold casting processes. The main materials provided include brass, aluminum bronze, and tin bronze, all conforming to national standard grades. These materials have distinct advantages in bearing applications:

Material Type Main Features Typical Applications Hardness (HB) Density (g/cm³) Friction Coefficient (Dry)
Brass Good machinability, moderate wear resistance, low cost Low to medium load machinery 70–100 8.4–8.7 0.35–0.45
Aluminum Bronze High strength, high wear resistance, corrosion-resistant Marine, metallurgical, heavy-duty machinery 160–240 7.5–7.8 0.20–0.30
Tin Bronze Excellent self-lubricating properties, corrosion-resistant Food machinery, low-speed high-load applications 120–180 8.5 0.15–0.25

2. Performance Optimization Strategies

2.1 Self-Lubrication

Zhejiang Shuangnuo Bearing Technology Co., Ltd. incorporates solid lubricants into the casting process to form self-lubricating composite materials, reducing friction and wear and extending bearing life. For high-load applications, tin bronze or aluminum bronze substrates combined with embedded lubricants are recommended.

2.2 Precise Composition Control

The company ensures product quality by independently casting raw materials. The casting process is fully monitored, and a spectrometer is used to test material composition before, during, and after the furnace to ensure consistency. Regular testing by national authoritative agencies is conducted for material composition and mechanical properties, guaranteeing product reliability.

2.3 Mechanical Processing and Surface Treatment Optimization

With over 80 advanced CNC machines and machining centers, the company ensures high dimensional accuracy of bearings. Combined with self-lubricating material properties, this reduces the friction coefficient effectively. Surface polishing, coating, or special heat treatment can be applied depending on application requirements to improve wear and corrosion resistance.

2.4 Process Optimization

Centrifugal casting is suitable for small to medium bearings, ensuring dense and uniform material with minimal defects. Continuous casting is ideal for mass production, maintaining consistent chemical composition. Metal mold casting achieves high precision for complex bearing shapes, improving machining efficiency.

3. Material Selection and Application Recommendations

  • Low-load, low-speed applications: Brass bearings are cost-effective and sufficient.
  • High-load, low-speed applications: Tin bronze bearings are recommended for self-lubrication and wear resistance.
  • High-load, high-speed or corrosive environments: Aluminum bronze bearings provide high strength and corrosion resistance.
  • Specialized or customized needs: Zhejiang Shuangnuo Bearing Technology Co., Ltd. offers tailor-made self-lubricating bearing solutions based on customer product characteristics and application requirements.
