CNC brass machining parts Oil Groove Brass Bushing
JDB-1U oil groove brass bushing. Based on high strength brass,
lubricating by oil added in the groove, which has the same
performance with tin bronze bushing but with much higher hardness,
the life time for low speed application is 2 times of tin bronze
bushing. It can be used in heavy load condition.
It mainly used in the joint of grab which with high load, and in
the huge gear box.
