Description
Technical Field
The invention belongs to the technical field of bearings, and particularly relates to a self-sealing cylindrical roller bearing.
Background
Conventional cylindrical roller shafts suffer from structural limitations due to the dimensions of the cage base thickness or cover thickness plus rivet head height being substantially close to the flange width. If a sealing element is added, the length of the roller is sacrificed, so that rated dynamic and static loads of the bearing are reduced, and the service life of the bearing is reduced. The fifth part called a bearing is sealed, so that dust and impurities outside the bearing can be prevented from entering the bearing, and the service life of the bearing is greatly prolonged. The enlarged width of the bearing adds sealing, which leads to the enlarged size of the host, is not beneficial to the miniaturization of host equipment, can greatly reduce the usage amount of lubricating grease for the accurate sealing of the rolling contact part of the bearing, and plays a role in energy conservation and environmental protection. The self-sealing cylindrical roller bearing structure can solve the problems, and the development of the self-sealing cylindrical roller bearing is becoming urgent.
