JDB-1U cast bronze bushing is based on high strength brass or other material based on your choice, lubricating by oil added in the oil grooves. This type cast bronze sleeve bushing has the same performance with other oiles bearing.but with much higher hardness, twice life time for low speed application compared with tin bronze bushing. It's also called cast bearing, brass bush,cooper bearing, solid sliding bearing,oil grooves plain bearing,cast bronze bearing,cast bronze and so on.
Standard material: CuZn25Al5.
Other material can be made based on customer's requirement.
Oil groove types:
Machined cast bronze bearings offer technically and economically favorable bearings solutions.
High load capability, low weight and good corrosion resistance.
The tolerance is much tighter than wrapped bronze bushes.
All kinds of oil grooves can be choosed,lubricating by oil filled in the oil grooves.
