Cylindrical Bimetal Bushings in 800 metric size are composite bearings that feature a unique combination of two different metals. These bushings are designed to provide superior wear resistance, corrosion resistance, and mechanical strength, making them ideal for a wide range of industrial applications.

The 800 metric size cylindrical bimetal bushings consist of a steel or similar strong base material, which is bonded to a softer, more wear-resistant outer layer. This outer layer, often made of a bronze, brass, or copper-based alloy, ensures smooth and reliable operation while handling heavy loads and resisting impact and vibration.

These bushings are extensively used in industries such as  construction, agriculture, and manufacturing, where they are exposed to extreme temperatures, pressures, and harsh environmental conditions. The bimetallic construction of these bushings ensures they can withstand such harsh environments and provide consistent performance over long periods.

Additionally, the soft outer layer of the bushings can be impregnated with oil or grease to create a self-lubricating surface. This reduces friction and wear, further extending the service life of the bushings and reducing maintenance requirements.

JF bimetal composite bearings use high-quality low-carbon steel as the matrix, and the surface is sintered with low-friction copper alloys (CuPb10Sn10, CuPb6Sn6Zn3, CuPb24Sn4, CuPb30, AlSn20Cu, CuSn8Ni) as the wear-resistant layer of the bearing.

The copper alloy surface can be used according to the working conditions Various types of oil grooves, oil holes, oil pockets, etc. need to be processed to suit the occasions where it is not possible to continue to refuel or it is difficult to refuel. The material can get good joint strength and best bearing capacity through secondary sintering and secondary extrusion.

Bimetal self-lubricating bearings, bearing bushes and thrust washers are made of high-quality low-carbon steel and sintered bronze powder. The surface is suitable for rotating and swinging movements under high load and low speed. It has the characteristics of low friction coefficient, good wear resistance, long service life and good anti-seizure performance.

Bimetallic Steel Bushing Sleeve Material: CuSn10Pb10

1. The copper/aluminum-lead alloy sintered layer, as the working layer of the bearing, provides good lubrication performance, and has good fatigue resistance and seizure resistance.

2. Low carbon steel base plate provides bearing capacity and heat transfer function.
