Bimetal sleeve bushing consists of a high quality low carbon steel backing carring a sintered tin-lead-bronze alloy (CuSn10Pb10) as a sliding layer. In order to improve tribological behavior the
sliding layer can be machined with ball shaped indents to store oil
or grease. In case of corrosive environment the backing can be
copper plated. Products of bimetal bushing series are applied in
operating conditions under medium loads, medium or high running
speeds and high impact loads.Bimetal Bushing is used for wrapped
bushes, thrust washers and bushes in connecting rods of gas
engines, etc.Steel shell 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.

Bimetal an external self-lubrication oil hole the designed oil
pockets, grooves and holes are suitable for lubricated application
to improve the PV value.
Bimetal Bearings, the bearing alloy layers include lead bronze,
lead-free bronze and lead-free with solid lubricant for high
performance.
Bimetal bearing is made of high-quality cold-rolled steel plate with CuPb10Sn10 copper-lead alloy sintered on the surface as the bearing surface
material, and various types of oil groove, oil hole or oil hole can
be processed on the surface of the alloy layer according to the
working conditions.
This kind of bearing not only has high fatigue strength, bearing
capacity and impact resistance, but also has good corrosion
resistance, suitable for medium speed under medium load and
occasions with large impact load.

Bearing Application Requirements
Pump Bearing Solution
External gear pumps and motors mounted with hydraulic bushing
blocks are widely used in many industries such as construction,
agriculture, automotive and material handling equipment and
chemicals.
These industries seek both to improve the performance and reduce the size and weight of their equipment to meet stricter
environmental and economic constraints.
A gear pump uses the meshing of gears to pump fluid by
displacement. They are one of the most common types of pumps for
hydraulic fluid power applications. Gear pumps are also widely used
in chemical installations to pump high viscosity fluids.
External gear pumps and motors mounted with hydraulic bushing
blocks are widely used in many industries such as construction,
agriculture, automotive and material handling equipment and
chemicals.
What is hydrodynamic Gear Pump Bearing Bushings?
Hydrodynamic Gear Pump Bearing Bushings is a kind of oilless
bearing special designed for Hydrodynamic, External gear pumps and
motors mounted with Hydrodynamic bushing blocks are widely used in
many industries such as construction, agriculture, automotive and
material handling equipment and chemicals.
