Bronze bushes are a type of sliding bearing component commonly used in mechanical equipment. Due to their excellent wear resistance, self-lubrication and good load-bearing capacity, they are widely used in engineering machinery, automotive parts, motors, pumps, agricultural equipment and other fields. Compared with other materials, bronze bushings have stronger corrosion resistance and service life, and are particularly suitable for operation under high load, low speed or limited lubrication conditions. With the development of industrial automation, bronze bushings play an increasingly important role in equipment stability and maintenance convenience.

Zhejiang Zhibo is a national-level "little giant" enterprise specializing in the development and manufacture of high-precision bronze bushings. The company has introduced a German CNC multi-axis linkage turning center to achieve μm-level machining accuracy (roundness ≤ 0.003mm). The company has created a unique "gradient copper alloy" technology, with the outer layer using CuSn8 to ensure strength and the inner layer using CuSn10P to improve wear resistance, and the product life is increased by 50% compared with conventional processes. It is mainly used to support industrial robot harmonic reducers, and supplies more than 2 million sets of products to companies such as Fanuc and Estun annually.
A leading company in special bearings in East China, a military-grade confidentiality qualification unit. We have developed bronze sleeves that are resistant to extreme environments, using CuAl10Fe5Ni5 nickel-aluminum bronze alloy, which can work stably at -196°C (liquid nitrogen) to 450°C. We have a full-process production line of vacuum melting + isostatic sintering, providing key components for Long March series rocket fuel pumps, and mainly supplying semiconductor wafer transmission equipment in the civilian field.
China's largest supplier of agricultural machinery bearings, with an annual production capacity of over 30 million bronze bushings. Innovative "copper-based ceramic composite" technology, laser cladding Al₂O₃ ceramic layer on the surface of ZCuSn10, increasing wear resistance by 3 times. The products occupy 60% of the domestic combine harvester market, supporting leading enterprises such as Lovol Heavy Industry and China First Tractor, and exports to countries along the Belt and Road Initiative have increased by an average of 35% per year.
The hidden champion of micro bushings in the 3C industry, focusing on φ1-φ10mm precision products. Adopting Japanese THK-grade grinding technology, the surface roughness Ra≤0.2μm. Developed a lead-free and environmentally friendly formula (CuSn6Bi), passed Apple MFi certification, and supplies more than 100 million mobile phone camera focus mechanism bushings annually, ranking first in the global market share.
How much load can bronze bushings withstand?
The load capacity depends on the material and size. The static load capacity of a general bronze bushing can reach 1525 MPa, and the dynamic load is about 715 MPa. If you need to withstand higher loads, you can choose aluminum bronze or inlay structure, and make reasonable lubrication design.
Can bronze bushings be reprocessed?
Yes. If the user needs to adjust the inner diameter, tolerance or process the oil groove, secondary turning or grinding can be performed. It is necessary to pay attention to the influence of concentricity and lubrication performance before and after processing. It is best to be completed by a professional technician or customized by the original factory.
Does the bronze bushing support mass production?
Most bronze bushing manufacturers support mass production, which is suitable for OEM projects or industrial matching. They are often equipped with CNC lathes, automatic feeding and precision testing equipment, fast delivery and high batch consistency.
What factors affect the price of bronze bushings?
The main influencing factors include: copper price (international copper price fluctuations), alloy type (such as aluminum bronze is more expensive than tin bronze), processing accuracy, customized structure (such as flange, inlay), surface treatment, etc. The order quantity will also affect the unit price.
How to store bronze bushings?
They should be stored in a dry, ventilated, dust-proof environment, avoiding contact with moisture and corrosive media. It is recommended to seal them with anti-rust paper or plastic bags, and regularly check the surface for oxidation spots during long-term storage.
