JF20 High Percentage Alluminum Alloy AISn20Cu Bushings Bitemal Bearings
JF-20 is a bearing with high percentage of tin and aluminum composition.With stecl as back and press AISn20Cu as lining.the bushing is of fairly good performance in anti-fatigue,load capactty,anti-corrosion and smooth sliding movement.It is widely applied under high speed and low load.It can be made into bearing shells for internal combustion engine with mid or low power or bearing shells for trains,air compressor and coling machines.It is a good substitution for Babbit material.
Sliding layer can be machined with lubricating grooves and/or with grease indents
Aluminum-tin alloy for hydrodynam-ic applications
Steel+AlSn20Cu
JF-20 high percentage of tin with aluminum alloy bushing is backing on low carbon steel, pressed with AISn20Cu as liner. It has fairly good performance in anti-fatigue and good load capacity, anti-corrosion and smooth sliding movement.
It usually used as engine bearing with middle or low power, air compressor bushing. It is a good substitution for Babbit material.
