Copper sleeve, Self lubricated bearing, used in a variety of large, heavy machinery, machinery is an important component.
Copper sleeve, copper bearing, used in various light industry, large, heavy machinery, is an important component of machinery.The product has the traditional tin bronze bearing function, takes the electrolytic copper as the raw material to match with many kinds of trace metal elements, through the high temperature sintering, through the air pressure centrifugal casting processing becomes.High hardness, excellent wear resistance, not easy to die, good casting performance and cutting performance, good corrosion resistance in the atmosphere and fresh water.In the absence of lubricants and water-quality lubricants, good sliding and self-lubricating properties, easy cutting, poor casting performance, good corrosion resistance to dilute sulfuric acid.Structural parts for general use, simple castings for ships, instruments, etc., such as sleeve, bushing, bearing bush, sliders, etc.
VIIPLUS supply full series of Sleeve Sintered Sleeve in material Bronze 663; CuSn90-10,Cast Bronze BushingsStainless Steel Bushings.
Chemical Composition- Copper (87-90%), Tin (8-9), Iron (1.0% Max) Carbon (0.1%), other elements less than 0.1%
ASTM: B438 Grade 1, Type 2 Class A
SAE 841 - Bronze Mil-B-5687 Type 1, Grade 1
Ideal for heavy loads at moderate speeds or light loads at high speeds - max Pv 50,000, P-Load 2,000, V-SFM-1,200
Self-lubricating - when in motion oil rises to the surface for lubrication and restores itself when at rest.
After forming, sintering and sizing, the bearings are vacuum impregnated with SAE 30 oil that provides lubricant which is metered from the bearing to the shaft during rotation.
Standard off-the-shelf oil impregnated bronze bearings should function satisfactorily in temperatures ranging from 10F to 220F.
RoHS, REACH, DFARS compliant
