An eyelet machine includes a frame, a lower mold, a threaded rod, an upper mold and a bearing assembly. The frame includes a lower beam, an upper beam, and a post formed between the lower and upper beams. The lower mold is adapted for carrying a first washer of an eyelet and supported on the lower beam in a detachable manner. The threaded rod is connected to the upper beam so that the threaded rod is translatable relative to the upper beam when they are rotated relative to each other. The upper mold is adapted for carrying a second washer of the eyelet and connected to the threaded rod in a detachable manner so that they are translatable together. The bearing assembly is provided between the threaded rod and the upper mold and adapted for taking a load along an axis of the threaded rod.
