Jdb soild lubricant embedded bushing
Jdb soild lubricant embedded bushing is a new type made from strong brass and homogeneously embedded with solid lubricant in its body. It breaks through the limit of general bearing whose lubrication depends on oil film, so heavy duty, anticorrosion, or where oil is hard to be introduced .Lts performance doubles both on hardness and wear-friction. It is now widely applied in successive casting machines, mineral machine, ships, turbogenerators, hydraulic turbines and injection molding machines etc.
Fb090 bronze bushing
Fb090is s kind of bushes wrapped by bronze strip. The bronze is of particular formulation with high specific gravity and on its surface may be incorporated with spherical or diamond shaped indentations or oil grooves as required by customers. It is of high load capacity and long life. In place of traditional bronze bush, it is more cheap and more compact. It is widely applied in hoisting machines and other construction machines, automobiles, trucks, machine tools and me mineral engines
Base material:cusn8p0.3
Hardness:hb90~120
Load capacity:75n/mm2
Temperature:-80~200c
Speed limit;2.5m/s
Pv limit(oil): 16n/mm2.M/s
Dx boundary lubrication bushing
Dx boundary lubrication bushing is based on a composite material with 3 firmly bonded layers:steel as backing, sintered bronze spherical powder as interlayer and modified pom as lining layer. It fits well for low speed, heavy duty and normal temperature and saves cost and prolongs working life when replacing normal all copper sleeves. If is widely applied in auto chassis, forging machine, metallurgical and mining machine, civil engineering, power station, strip rolling industries, etc.
