A single-pocket segmented cylindrical roller bearing cage

Abstract

This utility model belongs to the field of bearings, specifically relating to a single-pocket segmented cylindrical roller bearing cage, comprising several cage units, which together constitute the entire cage frame. Each cage unit includes a single pocket structure and two half-pocket structures located on both sides of the single pocket structure. The half-pocket structures of two adjacent cage units combine to form an integral pocket structure. This utility model eliminates the edge beams of segmented cages, forming a central beam structure. A separate cage is installed every other roller, avoiding the problem of adjacent cages having double the beam width. This reduces the circumferential space occupied by the cage in the bearing, increases the number of rollers, and enhances the bearing's load-bearing capacity. Simultaneously, there is no collision or impact between cages, reducing the risk of cage breakage.
