The bolted roller bearing is a tight machine element, and the fast and light installation of the bearing on the plane of the equipment frame can be realized through the bolt shaft. Existing bolt-type roller bearing tumbling bodies are mostly needle rollers or single or double row cylindrical rollers, and their full complement structure can withstand heavier radial loads, but cannot withstand the middle of the movement of some heavy machine tools or heavy transmission equipment. Large skewing moments and bidirectional axial loads due to misalignment, skewing or short hits. At the same time, limited by its own layout, it is difficult to achieve reliable sealing. Creation content This new application provides a bolt-type sealed double-row full-complement angular touch ball roller bearing that can withstand large axial loads and overturning moments in view of the bidirectional axial load and skew moment existing in the actual use of bolted roller bearings. In order to realize the above-mentioned vain attempt, this application model adopts the following technical plan: a bolted roller bearing, including an outer ring, a bolt body, a short inner ring and two rows of steel balls, its characteristics are: the bolt body includes a head, a journal and a rib. The head of the bolt body and the short inner ring are respectively provided with an inner ring channel. The short inner trap is on the journal of the bolt body and the narrow end face of the short inner ring is in contact with the narrow end face of the head of the bolt body. The short inner ring cooperates with the journal of the bolt body by interference. The ring channel is filled with steel balls in two rows between the inner and outer ring channels. The outer ring of the bolt roller bearing adopts a full complement cylindrical roller bearing with a thick outer ring wall. The outer diameter of the roller has a cylindrical and arc shape, which can be matched with the raceway surface according to the application plan. It is widely used in various industries, such as machine tools, metallurgy and other industries. The outer ring of the organization roller bearing adopts a full complement cylindrical roller bearing with a thick outer ring wall. The outer diameter surface of the roller has cylindrical and arc shapes, which can be matched with the raceway surface according to the application site plan. With this outer ring, the rollers can simply turn on the raceway and can accept heavier loads and shock loads. The bearing is a sealed structure, filled with greasy grease, and the supply is always effective and greasy, and users can avoid greasy. For harsh application conditions, it can be planned to supplement the channel of grease to improve the service life of bearings. Improper purchase of bolt roller bearings can also cause roller bearing fever. Greasy can reduce the wear of parts in motion, ensure the accuracy of the press, reduce energy consumption, and reduce the oil to thin oil, thick oil, etc. The main roller is the most important bearing body in the middle of a set of composite rollers. It mainly accepts vertical loads and impact loads, and has very strong impact resistance, wear resistance and corrosion resistance. Since the main roller is a full complement roller bearing, it can also be used alone as a one-way bearing.
