JF-800Bimetal Wrapped Bearings

No.1 JF-800 CuSn10Pb10
  • JF-800 bi-metal bushing is based on steel and sintered with CuPb10Sn10 or CuSn6Zn6Pb3 as a lining layer.
  • The strongest type of bi-metal bushings and widely applicable in so many fields.
  • This type has the best performance within the range of Cu-Pb alloy constructed bushing.
  • Therefore it has a wide application and is mostly suitable for where is middle speed and high impact etc.
  • Very good resistance to fatigue strength , with high shock resistance and good corrosion resistance.
  • Fit for middle load , high speed, bushes, washer and connecting rod bearing in internal combustion engine used in mechanical equipment and high shock bushing.

Material:CuPb10Sn10

Hardness:HB 70-100

JF-720 Bimetal Wrapped Bearings

No.2 JF-720 AlSn20Cu
  • JF-720 is a bi-metal bushing with steel as backing and sintered CuPb24Sn24 as lining layer.
  • This type has fairly good performance in anti-fatigue and load capacity.
  • It is suitable for middle speed and middle load.
  • When over plated certain soft alloy, it can be applied in high-speed internal combustion engine and as connect rod .
  • Good resistance to fatigue strength and high load capacity ,good performance of sliding, liable to be corrupted by lubricating oil.
  • Middle load middle speed, principle axis of internal combustion engine.

No.3 JF-700 CuPb30
  • JF-700 is a bi-metal bushing with steel as backing and sintered CuPb30 as lining layer.
  • It has good performance in anti-seizing, alien substance contamination.
  • It is necessary to be overplated certain soft alloy and mostly applied in internal combustion engine under high speed and middle to low load, e.g. main bushing of inner-combustion engine and connect-rod bushing.
  • Good resistance to fatigue strength and high load capacity,shock resistance and corrosion.
  • Principle axis of internal combustion engine,connecting rod bushing.

Material:CuPb30

Hardness:HB 40-60

JF-20 Bimetal Wrapped Bearings

No.4 JF-20 AlSn20Cu
  • JF-20 is a high tin and aluminum based bushing, which adopts steel as backing and is coated a lining of AlSn20Cu through rolling treatment.
  • It is a fairly good fatigue resistance, load capacity and good anti-corrosion and also performs well in Bushing's sliding properties.
  • It is widely applied under high speed and low load such as in internal combustion engine, air compressor and cooling machine.
  • Good performance of anti-seizing,covering eyewinker,soft alloy be plated on working surface.
  • High speed, middle or low load, principle axis internal combustion machine.
