Oilless bearings, specifically those made from ZCuAl10Fe3 aluminum bronze through the casting process, offer a robust and long-lasting solution for a wide array of industrial applications. The aluminum bronze material, with its unique composition of copper, aluminum, and iron, exhibits excellent mechanical properties, including high strength, good wear resistance, and corrosion resistance.
The casting process ensures a dense and uniform structure, resulting in bearings that are both strong and reliable. The oilless design eliminates the need for lubrication, significantly reducing maintenance requirements and operational costs.
Furthermore, the bushings, as a critical component of the bearings, are precision-cast to ensure a tight and secure fit. This ensures smooth operation and reduced friction, even under high loads and speeds.
Overall, ZCuAl10Fe3 aluminum bronze oilless bearings, with their bushings cast to precision, provide a highly efficient and cost-effective solution for various industrial machinery and equipment.

Self-lubricating guide solid lubrication wear-resisting plate precision mold standard parts
The guide part is an indispensable and important component in the die. Its function is to determine and maintain the relative position between the upper and lower die or other parts of relative motion is accurate, and to maintain the motion steering accuracy. The self-lubricating guide refers to the guide parts with good self-lubrication and friction after special process treatment, which can also be called oil-bearing guide parts. It is mainly used in large and medium size, fine and long life molds with high guidance accuracy.
Features of self-lubricating guide:
The self-lubricating guide parts produced by Jiaxing Gurun are filled with special solid lubricants such as graphite, MoS2 and on the metal matrix working surface to make it have a certain bearing capacity and good self-lubricating and wear resistance. The main characteristics are as follows:
In the case of no oil, can maintain self-lubrication, so it can simplify the mold structure, reduce oil consumption, avoid oil pollution damage, purify the working environment.
Simple structure, convenient installation, can reduce the cost, reduce tooling manufacturing and maintenance costs.
Because it has good self-lubrication and wear resistance, even in bad working conditions, can also completely avoid the occurrence of "overburning" or "bite card" phenomenon
Tensile strength: 540MPa
Yield strength: 200MPa
Elongation rate: 15%
Brinell hardness: HB1080 (experimental force in newtons)
Main Features: High mechanical properties, good wear resistance and corrosion resistance, can be welded, not easy to braze.
Application examples: Heavy castings requiring high strength, wear resistance and corrosion resistance, such as bushings, nuts, turbines, and pipe fittings working below 250℃.
Manganese bronze Bushings is a kind of tin-free bronze with manganese as the main alloying element. In addition to manganese, zinc, nickel, aluminum and other alloy elements are often added. Commonly used grades are QMN1.5. Has good mechanical properties, can be cold or hot plastic processing, heat and corrosion resistance. Melting ingot system, pressure processing into timber. Suitable for manufacturing high temperature working parts, such as steam boiler fittings and joints, bearings, steam valves, spark plugs, electronic instrument parts, etc.
CAST BRONZE BEARINGS
1) Casting (castability)
Refers to the properties of metal materials that can be cast to obtain qualified castings. Foundability mainly includes fluidity, shrinkage and segregation. Fluidity is the ability of a liquid metal to fill a mold. Shrinkage refers to the degree of volume shrinkage when the casting solidifies; Segregation refers to the inhomogeneity of the internal chemical composition and structure of the metal due to the difference in the sequence of crystallization during the cooling and solidification of the metal.
(2) malleability
Refers to the performance of metal materials that can change shape without cracking during pressure working. It includes in the liquid or cold state can be cast and forged, rolling, stretching, extrusion and other processing, the quality of the malleability is mainly related to the chemical composition of metal materials.
(3) Machinability (Machinability, Machinability)
Refers to the degree of difficulty that a metal material becomes a qualified workpiece after being machined by a tool. Cutting machinability is often used to measure the surface roughness of the workpiece after processing, allowable cutting speed and the degree of tool wear, it is related to the chemical composition of metal materials, mechanical properties, thermal conductivity and work hardening degree and many other factors, usually with hardness and toughness for cutting machinability is roughly broken. Generally speaking, the higher the hardness of metal materials, the more difficult to cut; Although the hardness is not high, but toughness, cutting is very difficult.
(4) weldability (weldability)
Refers to the adaptability of metal materials to welding processing. It mainly refers to the difficulty of obtaining high-quality welded joints under certain welding process conditions. It includes two aspects: one is the bonding performance, that is, under certain welding process conditions, a certain metal forming welding defect sensitivity; The second is the use of performance, that is, under certain welding process conditions. Applicability of certain metal welded joints to service requirements.
