The utility model relates to a balance pistion of press which moves reciprocately upwards and downwards in the balance cylinder body to balance the press slide block and upper die weight, which is a component dedicated for balancing press slide block and belongs to the press technology field. The utility model is an improvement of the prior press balance cylinder piston structure, by arranging oil holes onto the upper end surface and the external round surface and asbestos cords from the oil holes to the oil tank on the upper end surface of the piston, the oil inside the oil tank will be introduced to the external round surface of the pistion by the asbestos cords, which is beneficial to the lubrication oil storage and lubrication, thereby the lubrication condition between the pistion and the cylinder body is improved, nont only the service life of the balance cylinder pistion but also that of the balance cylinder is prolonged, the malfunction rate of the machine is reduced. The utility model with simple and
