Sliding bearing & copper brass bushing is based on high-strength copper alloy for the matrix, forming a solid lubricant embedded into the bearing, slider, etc.. The product broke the general bearings depend on the boundaries of lubrication oil film, and apply oil-free, high temperature, high load resistance, corrosion resistance and in the water or other chemical solution can not come on lubrication under special conditions of use. Current products have been widely used in metallurgical continuous casting machines, rolling mill equipment, mining machinery, ships, steam turbine, hydraulic turbine, injection molding machine and equipment production line in.
