SOB Oiles Bronze Bush
SOB Oiles Bronze Self-lubricating 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.
SOB oiles bronze bush is a oilless slef-lubricating bearing.It is in brass or bronze base with SL2 graphite lubricants plugged
