[0012] 1. The cylindrical roller bearing with convenient installation is provided with a limit hole, a limit block, a spring, a ball and a movable rod. When the first outer ring and the second outer ring need to be installed, the movable rod and the sleeve are aligned first. At this time, the plastic pad is pressed to drive the round cap and the movable rod to move down, and the sleeve pushes the two balls so that the two balls and the limit block are close to each other. When the ball moves to the limit hole, the spring resets to push the limit block and the ball apart, so that the limit block is inserted into the limit hole, and the installation of the first outer ring and the second outer ring is completed. When the first outer ring needs to be installed, When disassembling the outer ring and the second outer ring, press the two balls to make the limit block disengage from the limit hole. At this time, the limit hole does not limit the limit block, so that the tension spring is reset, and the movable rod is pulled out of the sleeve. At this time, the first outer ring and the second outer ring can be disassembled. Through the convenient installation and disassembly of the first outer ring and the second outer ring, when the rolling body is damaged, there is no need to knock the cylindrical roller bearing off the rotating shaft, so that the rolling body is replaced easily, the operation is simple, and it is not easy to cause secondary damage to the cylindrical roller bearing.

[0013] 2. The cylindrical roller bearing which is easy to install is provided with a guide rod, a guide groove, a sleeve and a limit block. When the movable rod is inserted into the sleeve, the guide rod slides in the guide groove. The guide rod and the guide groove have a guiding function, so that the limit block and the limit hole can be aligned. There is no need to rotate the movable rod multiple times to align the limit block and the limit hole, thereby improving the convenience of operation and further improving the installation efficiency.
