Oil-less slide bushes

Oil-less slide bushes are low friction co-efficient, anti-wear, anti-corrosion and can be used without oil, or only a trace of oil is needed. Moreover, it is of low cost, low vibration and low noise, compact and light, and can form a transfer film of PTFE which protects the mating surface from scoring. This is widely applied in various sliding articles of different kind of machines such as printing machines, textile machines, tobacco machines, gymnastic machines, hydraulic vehicles, automobiles, motorcycles, agriculture and forests machines and so on.

Boundary lubricating bushes

This is a steel based, spherical bronze powder as interlayer and overlaid by a layer of modified polyacetal copolymer plastics(POM), the surface of which is provided within oil indentations, and so it is known as boundary lubricating material. The thickness of the plastic layer is about 0.5mm.A trace of oil or grease may be utilized and may work successfully under heavy load with oscillating motion and those which start and stop frequently under loads. Moreover, it is of low cost and long life.This kind of material is now widely used as bushes in chassis of automobiles,foring press,metallurgical and miningmachines, civil engineering machines, hydroelectric industrial machines and steel strip cold rolling machines.

Solid Lubricants-Embedded bushes

This is a kind of high strength cast bronze based material and on the surface of which embedded with preformed solid lubricant. So it can be made into bearing, plate, thrust washes and soon. It has both the virtues of the copper alloy and the solid lubricant, can be applied under dry, high temperature, high pressure, corrosive, water or other chemical environments where no oil can be introduced. This is now used in successive casting machines, steel rollers in metallography, mineral machines, ships, turbogenerators, hydraulic turbines and injection molding machines for plastics.

Bronze bushes

This is a 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. This is of high load capacity and long life. In place of traditional bronze bush, it is cheaper and more compact. This type of bush is widely applied in hoisting machines and other construction machines, automobiles tractors, trucks, machine tools and some mineral engines. It can be fabricated into bushes, half bearings, flanged bushes, thrust washers, spherical bearings and so on.
