Bimetallic bearing bronze metric cylindrical bushes are precision-engineered components that offer superior wear resistance and durability in a wide range of applications. These bushings are constructed using a bimetallic design, typically combining a steel backing with a bronze alloy overlay.
The bronze alloy, often CuSn10Pb10 or a similar composition, provides excellent self-lubricating properties and resistance to wear, corrosion, and fatigue. This allows the bushings to maintain a smooth and reliable surface for rotating components to operate on, even under heavy loads and high-speed conditions.
The metric cylindrical design of these bushings ensures a precise fit and alignment in metric-sized shafts and housings. This precision allows for reduced friction, vibration, and noise, resulting in improved efficiency and longer service life.
Bimetallic bearing bronze metric cylindrical bushes are commonly used in industrial machinery, automotive components, and other demanding applications where reliability and durability are crucial. They are suitable for applications with varying loads, speeds, and operating conditions, making them a versatile and reliable choice for a wide range of industries.
Wh you need replacements for worn-out bushings or are looking for new bushings for a new machine, bimetallic bearing bronze metric cylindrical bushes offer an excellent solution. Contact your trusted supplier today to learn more about these precision-engineered components and how they can improve the performance of your equipment.

bimetallic bearings with steel backed bronze bushings are ideal for applications with high loads & rough operating conditions. Wear resistance.
bimetal bearing is made of steel sintered with CuPb10Sn10 or CuSn6Zn6Pb3 as a lining layer. This type of bushing shows its best performance among bushings made of Cu-lead alloy material in this product range. It suits most for middle speed and high impact conditions.

Steel backed with a lead bronze lining bearing material for oil
lubricated applications. This material has high load capacity and
good fatigue properties. It is widely used in automotive
applications such as compressors, steering gear, power steering,
pedal bearings, king-pin bushes, tailgate pivots, mechanical
handling and lifting equipment, hydraulic motors, agricultural
machinery, etc.

1.Bi-metal sintered bronze layer: good wear resistance and
excellent load capacity.
2. Steel Support: By laying the foundation of the bushings, the
steel support offers exceptional stability, load and heat
dissipation characteristics.
