The invention relates to a needle bearing. The needle bearing comprises a bearing main body. An end of the bearing main body is provided with a stepped round. The bearing main body is provided with a snap ring groove. A snap ring is arranged in the snap ring groove. The outer surface of the bearing main body is a helicoidal surface. The outer surface of one end of the bearing main body is provided with the snap ring groove and is fastened by the snap ring so that the bearing main body does not fall off from a base hole in work, bearing work efficiency is improved, enterprise normal operation is guaranteed, over consideration on an assembling tolerance factor in assembling is avoided, and enterprise production efficiency is improved.
Description
technical field [0001] The invention relates to a bearing, in particular to a needle roller bearing. Background technique [0002] At present, if the main bearings on the market are installed too tightly, they will be directly pressed on the needle rollers, which will block the axial clearance of the bearings and affect the normal operation of the bearings; This will cause the needle roller to displace in the axial direction at will and fall off from the bearing, making the bearing unable to work normally and affecting the normal production of the enterprise. Contents of the invention [0003] In order to solve the above problems, the present invention provides a needle roller bearing with simple structure, firm connection and stable operation. [0004] The technical solution of the present invention is: comprising a bearing main body, one end of the bearing main body is provided with a stepped circle, the bearing main body is provided with a snap ring groove, and a snap ...
