Bronze slide bearings provide good wear resistance, corrosion protection, and a naturally low friction coefficient. They are hollow cylindrical components, available with one, two, or no flanges, and are designed to extend and support rotating shafts in machinery of all sizes, from light-duty to heavy-duty and even extra-heavy-duty equipment. Made from copper-based alloys, these bearings minimize friction between moving parts and perform reliably under demanding or continuous working conditions. Their self-lubricating properties keep the bearing running smoothly, even when oil lubrication is limited, which helps reduce wear and maintenance frequency. Each bronze slide bearing is custom-made according to specific equipment requirements and intended applications, with micron-level precision that guarantees consistent quality and long service life.
Clients can choose among several bronze alloys, each selected based on performance needs and application type. Commonly used grades include C95400, C91700, and C83600, as they offer the right balance of strength, wear resistance, and stability.

Bronze slide bearings are used in a wide range of industries and operating conditions, including:
They can operate under extreme conditions such as heavy loads, high temperatures, impact, reciprocating motion, and limited lubrication.
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.
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.
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.
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.
From bronze bushings and bearings to customized wear components, we’re here to help you find the right solution for your equipment.
When evaluating new suppliers, buyers usually check ISO9001 quality management, environmental and safety certifications, material traceability, and other industry-specific approvals to ensure product reliability and compliance.
Bronze eccentric bushings are made from high-lead bronze alloys such as ZCuPb10Sn10, ZCuPb15Sn8, and ZCuPb20Sn5. These alloys provide excellent self-lubricating, anti-seizing, and wear-resistant properties, allowing stable performance even under strong impact and heavy dust exposure. The wear resistance can also be enhanced through customized designs to meet the demands of abrasive working conditions.
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.
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.
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.
