David from CanadaOur company import the bronze gleitlager from viiplus china,viiplus professional team makes sure customs clearance is always smooth. They provide an accurate bronze bushing classification, handle all the paperwork,We have received the self-lubricating bronze bushings. They look well done and the high quality.
Valerie from CaliforniaWe import the bronze gleitlager from China to under the incoterm FOB shanghai, sometimes by Air. viiplus is a very good bronze gleitlager supplier, they are very professional and patient, after we inform the new order, they will manufacturer bronze gleitlager in time and give us the schedule , and then we just need to receive the bronze parts
Daisy From GermanyThe best surface finishes for Sleeve Bearing, tighter concentricity, and bronze bushings material uniformity. The good supplier of standard inch and metric sleeve bearings and bushings from china.

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 the soft alloy is plated on the bushing surface and with oil lubrication, it can be applied in the high-speed internal combustion engine and connect-rod.
