Corrosion Resistance Cast Bronze Sleeve Bearings Machined CuZn25Al5
JDB-1U Machined Cast Bronze Bushing
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:
1. High load capacity
2. Self-lubricating under dry operation
3. Possibility to use in presence of fluids
4. Good chemical inertia to corrosive agents
5. Wide range of operating temperature
Cylindrical bushing, flanged bushing, thrust washer and slide plate are standard fabrication.
Special designs can be made according to your design.
