Oiles 500SP5-SL1 Special high-strength Brass Bearings, HTB2 Bronze Graphite Oiles Bearing Bushes
JDB-10S graphite plugged oilless bronze bearing is made of centifugal casting special high strength brass with graphite filled. The hardness of base material can be more than HB250.This type of self-lubricating bearing is also called #500 oilless bearing,brass oiles bearing,cooper sliding bushing,solid lubricant filled sliding bearing,500 oilless guide bushing and graphite filled bearing.
Material
CuZn25Al6Fe3Mn3+Graphite
PTFE or SL4 lubricant can be made based on requirement
