Home > SL4 PTFE Bronze Bearing
Solid Bronze Bearing is manufactured using high tensile manganese bronze plugged with solid lubricants. Basic bronze alloy material is CuZn25Al6Fe3Mn3 with graphite (SL2) plugged, we also provide widely optional choice from CuSn5Pb5Zn5, CuAl10Fe5Ni5, CuSn12, and other standards materials.
Especially our company have developed the SL4 solid lubricants for water contacting applications like jet, propeller, ship, boatyard, offshore platform, hydraulic turbine etc.
These products are mainly used in applications of high load & moderate speed. It has the ability to withstand the temperature up to 400oC. We also have the capability to develop these bushes and plates as per any specifications of our clients.
