Bronze Bushings

Wear-resistant copper-based alloy components for industrial equipment

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.

Features

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.

Applications

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

Applications of Copper Alloy Wear-Resistant Parts

In marine propulsion systems, corrosion resistance to seawater is a primary concern. Are bronze nuts and slippers suitable for such environments?

Bronze nuts and slippers are produced from high-strength copper-based alloys that offer excellent resistance to seawater corrosion. These alloys retain their mechanical integrity and surface stability over time, making them well suited for continuous operation in marine, humid, or chemically active environments.

For manufacturers of large CNC machines, guiding components require high-precision bronze bushings. Can the tolerance accuracy and surface finish be guaranteed?

High-precision bushings are manufactured through centrifugal casting, five-axis CNC machining, and polishing. With strict quality control and CNAS-certified testing, tolerance accuracy reaches ±0.025 mm and surface roughness Ra ≤ 0.8 μm, meeting the standards required for CNC systems.

As a trading company dealing in construction machinery components, it is important to know whether the products meet recognized international standards. Do bronze bearings comply with ISO or DIN requirements?

Yes. Bronze bearings are made following ISO and DIN standards for materials, precision, and surface finish. They can be used with equipment that is manufactured under international requirements, ensuring consistent performance across different applications.

As a distributor of copper alloy components for different industries, customers often request customized bronze nuts and sliding bearings. Can production be carried out based on provided drawings?

Bronze nuts, sliding bearings and other wear parts can be manufactured according to customer drawings and specifications. Each wear part will be manufactured with micron-level precision to match specific design or size requirements in different industries.

In excavators and loaders that experience frequent impact, can bronze bearings be made in a reinforced, thick-wall design to improve durability?

Reinforced bronze bearings can be produced with thick-wall construction to handle repeated shock loads. Through the use of composite materials, strengthened structures, and optimized processing, these bearings offer higher impact resistance and longer service life. Custom designs are also available to meet specific equipment requirements.
