Our metric size CuSn6Zn6Pb3 cast bronze bushings are designed to provide reliable and long-lasting performance in a wide range of industrial applications. Made from high-quality CuSn6Zn6Pb3 bronze alloy, these bushings offer excellent wear resistance, corrosion resistance, and load-bearing capacity.
The metric size ensures a perfect fit for various industrial equipment and machinery, ensuring smooth and efficient operation. The cast bronze construction provides superior strength and durability, making these bushings suitable for use in high-load and high-speed applications.
The CuSn6Zn6Pb3 alloy used in these bushings combines the advantages of copper, tin, zinc, and lead, resulting in a material that is both tough and lubricious. This allows the bushings to operate smoothly with minimal friction and wear, even under extreme conditions.
Our metric size CuSn6Zn6Pb3 cast bronze bushings are suitable for use in pumps, motors, compressors, and other rotating equipment. Wh it's in the automotive industry, heavy machinery, or any other industrial setting, these bushings are an excellent choice for improving the efficiency and reliability of your equipment.
With their high-quality materials and metric size, our CuSn6Zn6Pb3 cast bronze bushings offer a robust and long-lasting solution for enhancing the performance of your industrial systems.
Wide range of copper-based materials. Pre-turned or finalized ready for assembly parts. E-Cu, Bronze & Brass Alloys. Used for Bearing Cages, Sliding Bearings, Bushings.
Specializing In The Production Of Non-standard CuSn6Zn6Pb3 Graphite Phosphor Bronze Bearings,Graphite Copper Sleeve Special Brass Bushing made to order.
The cast bronze bushing (or plain bearing) is a hollow cylindrical component, such as a tube, and it is usually split in two, split with one, two, or even no flange and is used for axial expansion. They are parts that are subjected to frictional forces due to rotation and are used in light, heavy or super-heavy machines and equipment.
Viiplus bearing can offer different types of bronze alloys according to lifetime, service etc.
As a leading manufacturer of self-lubricating bearings and bushings, we offer many high quality products, such as steel bronze bushings, precision steel bushings, ejector guide bushings, hardened steel bushings, bimetallic bearings, post bushings driving and so on. These products are widely used in metallurgy, automobiles, mining, petroleum, rolling mills, chemical industry, engines, ships, printing machines and plastics.
This type of cast bronze bushing hardened steel bearings is intended for heavy duty applications on construction machinery. For better performance, hardening of the bushings can be treated with a special hardening process or QPQ process to achieve excellent hardness requirements and lubrication characteristics.
| Material Grade (GB) | Key Features | Applications |

It is not unusual to come across a cast bronze bushing that has
worked satisfactorily for decades.
In fact, a properly designed and maintained bronze bearing will
often exceed the life of the equipment it serves.
The relatively high hardness and good impact resistance of the cast
bronze bushing make it widely used in mechanical
engineering,earthmoving equipment, hydraulic cylinders, lifting
equipment, pumps and other bearings.
