The invention discloses a bridge support sliding material, which is prepared through following steps: mixing organic resin, fiber, solid lubricant and filler, stirring, pressing and sintering; the weight content of organic resin is 35-99.8%, solid lubricant is 0.1-30%, fiber is 0.1-20%, filler is 0-15%; the organic resin employs politef or super molecular weight polyethylene as resin basic material. The material is characterized by good self-lubricating property and abradability, large bearing capacity, which is two to three times of that of pure PTFE, good creep resistance, low production cost, and wide usage as support bearing for high speed Railway Bridge.
