A type of slide rail sub-assembly is constructed with an oil-free self-lubricating bearing lining plate of 1.5mm thickness welded onto a structural steel frame. The structural steel is made of 18Cr2Ni4WA alloy, and is used for supporting and ensuring the overall rigidity of the sub-assembly. The oil-free self-lubricating bearing lining plate is iftted into the slide rail tightly by stamping, of which the edges is jointed closely via electron beam welding. The study puts forward a structural design and manufacturing process for slide rail of high pressure fuel ram pump, which has the properties of anti shedding, fric-tion resistant, high precision, low friction coefifcient, low cost, and can withstand greater loads.
