The utility model relates to a front cover of an oil cylinder. The front cover comprises a front cover body, wherein sealing pieces are embedded in the inner wall of the front cover body, and an oil passing groove is arranged on the inner wall of the front cover body; one end of the oil passing groove is communicated with the inner end surface of the front cover body, and the other end of the oil passing groove is communicated with a groove in which the sealing piece is embedded. The front cover has the advantages that a large-pore-diameter ring-shaped oil passing hole in the front cover is changed into a spiral groove structure, a guiding ring groove and a guiding ring are omitted and rigid support of a spiral groove structure is adopted, so that the guiding length is increased, the eccentric wear resistance of a product is improved, meanwhile the impact of instantaneous pressure overload in a hydraulic system can be relieved, the service life of the product is prolonged and the manufacturing cost of the pro
