The pull-out type bearing storage box comprises a tank body, support cylinders, storage boxes, partitions, sliding slots and sliding blocks. The multiple support cylinders are fixed in to the tank body. Each support cylinder is in a cylinder shape and horizontally arranged. One end of each support cylinder is fixed to the inner wall ofthe tank body. The other end of each support cylinder penetrates the side wall of the tank body. Each storage box with an opening in the upper end is inserted into the corresponding support cylinder.Each sliding block is arranged on the outer wall of the corresponding storage box. Each sliding slot parallel to the corresponding support cylinder and matched with the corresponding sliding block isformed in the inner wall of the corresponding support cylinder. The sliding blocks are embedded into the corresponding sliding slots. A circular baffle is arranged at the side of the opening end, close to the corresponding support cylinder, of each storage box. The diameter of the baffles is the same as the inner diameter of the support cylinders. The multiple partitions vertically arranged are arranged in each storage box. According to the pull-out type bearing storage tank, the storage boxes are arranged in the corresponding support cylinders, and bearings can be effectively stored and are not likely to be contaminated by external dirt.
