The invention relates to a guide ring for an oil-free lubrication compressor. The guide ring comprises a guide ring body provided with an opening on one side; the guide ring body is made of filled polytetrafluoroethylene; the filled polytetrafluoroethylene comprises 50-70 parts of polytetrafluoroethylene, 30-40 parts of polyphenylene and 10-20 parts of glass fibers according to the mass ratio; a lubricating layer covers the outer peripheral surface of the guide ring body, and is pure polytetrafluoroethylene; and the thickness of the lubricating layer is 5-100 nm. The guide ring has the following beneficial effects: the wear resistance, the high-temperature resistance and the creep resistance of the guide ring are improved; and the lubrication between the outer peripheral surface of the guide ring and the inner wall of a piston cylinder is improved.
