ISO Cast Bronze Bearings CuZn25Al5 Cast Bronze Sleeve Bushing
JDB-1U Machined Cast Bronze Bushing
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.
