"Rhesent" solid lubricant bearings are produced based on the high-intensity bronze alloy with orderly arranged pores of appropriate size to contain solid lubricants.
This kind of bearing have good wear resistance, low friction, work without any oil for long period. It widely applies in the water conservancy project machinery, like dam gate bushes, tightening pulley sliding bearing, hydraulic turbine bushes, contruction machinery, bridge, chemical industry, metallurgy, petroleum, ship and has become the stereotypia product in each kind of project machinery. To meet the requirments of the customers and to suit more applications, our company developed with the substrate material bearing for selected.
Suitable for medical machines, textile machines and sport machines, transportation machines, transmission equipments, electronic products and agriculture industries, etc. As a result of this products fine material behavior, decided the "Rhesent" product suited the more used situation, is better than other similar products.
