Zusammenfassung:	The invention belongs to the technical field of bearing assembling and manufacturing, and particularly relates to a bearing front sealing device with an observation hole applied to a railway wagon bearing, which comprises a front cover arranged on one axial side of the bearing, the front cover is provided with the through observation hole, a sealing plug is assembled in the observation hole, the sealing plug is in interference fit with the hole wall of the observation hole, and the observation hole is communicated with the front cover. A plurality of grooves are formed in the side wall, making contact with the observation hole, of the sealing plug. The observation hole is formed in the front cover, so that when the bearing is abnormal or overhauled, the condition of the axle can be observed, normal operation of the bearing is guaranteed, and the service life of the bearing is prolonged. The sealing plug and the front cover are in interference fit, and the groove is designed in the side face of the sealing plu
