Description

Technical Field

[0001] The utility model relates to the technical field of cylindrical bearings, in particular to a self-sealing cylindrical bearing. Background Art

[0002] Cylindrical bearings are composed of a cage, rollers and guide rings, and are generally separable bearings.

[0003] According to the application number: CN202121350026.0, a self-sealing full-complement cylindrical roller bearing includes an outer ring: a cylindrical roller, wherein the cylindrical roller is arranged below the outer ring; an inner ring, wherein the inner ring is arranged below the cylindrical roller; a first baffle, wherein the first baffle is arranged on the rear side of the outer ring; and a snap mechanism, wherein the snap mechanism is arranged inside the first baffle. The self-sealing full-complement cylindrical roller bearing, by arranging the snap mechanism, enables the snap mechanism to fix the first baffle inside the outer ring and the inner ring, and by loosening the snap mechanism, the first baffle is separated from the outer ring and the inner ring, thereby achieving the purpose of quickly installing and removing the baffle.

[0004] In the above case, the baffle is fixed to the outer ring of the bearing through a spring or other structure, thereby sealing the inside of the bearing and preventing the loss of grease inside the bearing. However, fixing the baffle through a spring or other structure may easily lead to poor stability of the baffle after fixation, and the baffle may become detached after long-term use, thereby reducing the sealing performance. For this reason, we provide a self-sealing cylindrical bearing. Utility Model Content
