Bronze Bushes Description
Sintered bronze flange bearings and bushings are both self-lubricating sliding bearings made by powder metallurgy. The bushing is mainly cylindrical and is used to bear radial loads and reduce friction, while the flange bearing has a flange edge added to one end of the bushing. It can not only bear radial loads, but also play a role in positioning and bearing certain axial loads. Because its porous structure stores lubricating oil, it can continuously release lubrication during operation and is widely used in motors, automobiles and mechanical equipment.In the field of mechanical transmission and sliding friction, sintered bronze flange bearings and bushings are two widely used basic components. Based on the excellent performance of bronze materials, they are made through powder metallurgy sintering process, and have the characteristics of friction reduction, wear resistance, and self-lubrication. They play a key role in supporting, guiding and reducing friction in various mechanical equipment.

Flange Bronze Bushing Advantage
Long-lasting Self-Lubrication
The porous structure retains oil, ensuring stable operation even without continuous lubrication, reducing maintenance frequency.
Low Friction and Quiet
The bronze base, combined with its lubricating design, offers a low friction coefficient and significantly lower operating noise than rolling bearings.
Reliable Axial Positioning
The flange structure incorporates a built-in axial stop to prevent movement and simplify assembly and positioning.
Cost-Effectiveness
Mass-produced using a powder metallurgy process, the design is simple and less expensive than rolling bearings.
Adaptable to Complex Operating Conditions
Stable performance under low speeds, reciprocating motion, and impact loads, without the "slippage" issue associated with rolling bearings.
Moderate Temperature and Corrosion Resistance
The bronze material is resistant to atmospheric and freshwater corrosion, with a typical operating temperature range of -40°C to 120°C.
What is Powder Metallurgy ?
Powder metallurgy is an industrial technology that uses metal powder (or a mixture of metal powder and non-metallic powder) as raw material to manufacture metal materials, composite materials and various products through processes such as forming, sintering and subsequent necessary post-processing. It integrates knowledge from multiple disciplines such as materials science, metallurgy and mechanical engineering, and is one of the indispensable key technologies in modern industry.
Powder preparation: Metal powders with specific composition, particle size, and properties are obtained through methods such as mechanical crushing, atomization, or chemical reduction.
Powder mixing/alloying: Different types of powders are uniformly mixed in proportion, and lubricants are added as necessary to ensure compositional consistency.
Forming: The mixed powders are pressed into a green body (a compact) with a specific shape, size, and density using a mold or press.
Sintering: The compact is heated to a temperature below its melting point under a protective atmosphere or vacuum and maintained at this temperature to allow the powder particles to diffuse and bond, forming a dense product.
Powder Metallurgy Advantage
High material utilization
Powder metallurgy products can typically be formed in a single step, reducing the amount of cutting required.
Precise composition control
Powder mixing allows precise adjustment of material composition to create alloys or composite materials with specialized properties.
Uniform and stable performance
Due to the fine and uniform powder particles, the microstructure and properties of the sintered product are relatively uniform and reproducible.

Process Of Bronze Bushing
Powder laying: Firstly, decontaminate and deoxidize the steel plate surface, and then prepare the required copper powder;
Sintering: The copper powder material can be transformed into dense body in the sintering process. After the powder is formed, the dense body obtained by sintering is a polycrystalline material, which affects the performance of the material. According to different technical requirements and steel plate thickness, alloy copper powder with a certain thickness is evenly paved on the surface of the steel plate, then heated with high temperature oxygen isolation, and sintered at 700-900 ℃ for 30-90 minutes. The metal other than copper is partially melted, and the alloy powder becomes paste. After cooling, it is firmly sintered on the steel plate;
Blanking: Cut the steel plate and copper plate into the specified length and width according to the product requirements;
Oil pressure groove: Punch out the oil groove with designed size on the bimetallic plate;
Punching buckle: Set punching buckle at the edge;
Pre bending: Place the alloy plate on the pre bending die for pre bending;
Bending: Combine the two ends of the alloy parts bent at both ends with the bending die;
Rounding: Shape the alloy parts with guide posts;
Extrusion: While shaping, the side matching the shape radius of the alloy part and the pressing die are used for final shaping;
Integration: Level the two end faces of the alloy parts on the grinder, chamfer the mouth at both ends, and finally finish grinding the outside of the alloy parts.
