Bronze Bushings
-
Maximum Outer Diameter up to 4000 mm
-
Maximum Weight of a Single Piece 5 tons
Bronze bushings are made using 99.99% pure metal materials, carefully blended to meet both industry standards and specific customer requirements. Each batch of bronze bushings is produced using advanced centrifugal casting to keep the material structure consistent. Sample pieces are kept for up to five years so the material can be traced and verified whenever needed. The bushings are then precisely machined on imported CNC equipment. Every stage of production follows ISO9001 and CCS standards and is verified by testing in our CNAS-accredited laboratory.

Bronze bushings provide excellent wear resistance, corrosion resistance, and load-bearing capacity. They are widely used in machinery that operates under continuous or heavy-load conditions, ensuring reliable long-term performance. Some of their features include:
- High wear resistance: Made from durable copper alloys, the bushings maintain stable performance even in high-speed or heavy-load conditions. They reduce friction and surface wear, helping equipment operate smoothly for long periods.
- Corrosion resistance: Bronze performs well in humid or chemically active environments, which makes these bushings suitable for marine, chemical, and other demanding applications. They resist corrosion and extend the service life of machinery.
- Good thermal conductivity: bronze helps release heat quickly from moving parts, keeping the equipment cool and running smoothly, even during long or high-speed operation.
Bronze bushings are widely used in various types of heavy machinery and industrial equipment, including:
- Brake and suspension systems in trucks and other commercial vehicles
- Rotary crushers, single-cylinder and multi-cylinder cone crushers
- Agricultural machines such as tractors and harvesters
- Kaplan, Bulb, and Francis turbines, as well as power generators
- R&D Capability
We handle every production stage independently, from the development and casting of bronze wear parts to machining and quality inspection. This allows us to have full control over product quality and ensures that each process is backed by our proprietary know-how and patented technologies.
- Industry Experience
Backed by more than 40 years of experience, we specialize in bronze wear parts for wind power, mining, hydropower, marine, and oil extraction equipment. Our product catalog includes bronze and steel bearings, bushings, and other wear components. We have long-term partnerships with several Fortune 500 companies within these industries.
- Production Strength
Our workshop is equipped with 20 advanced five-axis machining centers from MAZAK and MAKINO, along with 35 imported turning and milling machines. The 5,000 m² temperature-controlled facility is operated by experienced CNC technicians who make sure every part is machined with accuracy and consistency.
- Quality Control and Certifications
We manage every step of production in-house, following ISO9001 and CCS quality standards to ensure consistent results. Our CNAS-accredited laboratory (CNAS L5937) and skilled inspection team handle all testing and verification, including material composition, hardness, tensile strength, and microstructure, along with non-destructive tests such as UT, PT, and VT. All procedures comply with GB, ASTM, ISO, JIS, and YS standards.
