JDB-30 Solid Lubricants Plugged Aluminum Bronze Self-lubricating Oilless Bearing
JDB-30 Aluminium bronze oilless bush is made of aluminium alloy base material with graphite, PTFE or SL4. This type of oilless bearing is also called oiles 500AB SL1 bronze bearing, bronze alloy oil free bushing, bronze graphited oilless bearing, graphite inlaid bronze bearing, solid lubricant sliding bearing, oilless 500 bronze bearing and JM7-15 self lubricating bearing.
CuAl10Ni5Fe5 + Graphite
PTFE or SL4 lubricant can be made based on requirement
