Bronze Bimetal Bearings CuPb24Sn4 DIN1494 Standard Type ISO9001 Certification
JF-720 is a bimetal bearing with steel back and sintered CuPb24Sn4 as lining.This type has fairly good performance in anti-fatigue and heavy load capacity.It is suitable for middle speed and middle load.When soft alloy is plated on the bushing surface and with oil lubrication,it can be applied in high-speed internal combustion engine and connect-rod.
