The present invention relates to a bearing device including a body formed with an inner groove that does not communicate with the shaft hole of the body. Thus, when the rotation shaft is rotated, the lubricating oil may lubricate the rotation shaft, and may flow back to be stored in the inner groove after the rotation shaft stops rotating, thereby achieving the effect of recycling use. At the same time, the inner groove does not communicate with the inner shaft hole, such that when the rotation shaft is rotated, the lubricating oil contained in the inner groove will not be directly carried out of the body and will not sputter out of the body. Thus, the amount of loss of the lubricating oil may be reduced, thereby increasing the lifetime of the bearing device.
