An oil inlet 14, a swivel joint 15 is fixedly installed on the top of the oil inlet 14, an oil inlet pipe 16 is rotatably installed on the top of the swivel joint 15, and the oil inlet pipe 16 is fixedly installed inside the positioning hole 7, the top of the oil inlet pipe 16 extends to the inner bottom end of the circular opening 6, a connecting thread 17 is provided on the top of the inner wall of the oil inlet pipe 16, a threaded plug 18 is installed on the top of the oil inlet pipe 16, and the threaded plug 18 is connected to the internal thread of the top end of the oil inlet pipe 16 through the connecting thread 17, and the threaded plug 18 is located inside the circular opening 6, and an end cap 19 is fixedly installed in the middle of the top end of the threaded plug 18, and the end cap 19 is a regular hexagonal structure.

[0022] During use, through the interaction of the bearing inner ring 1, roller groove 2, roller body 3, bearing outer ring 4, mounting groove 5 and lubrication assembly 8, the roller bearing can achieve self-lubrication during use, thereby improving the wear resistance of the roller bearing and thus increasing its service life.

[0023] Working principle: When working, first rotate the end head 19 to drive the threaded plug 18 to open from the top of the oil inlet pipe 16, and then add lubricating oil through the oil inlet pipe 16. The lubricating oil enters the interior of the cylindrical oil cylinder 9 through the oil inlet pipe 16, the rotating joint 15 and the oil inlet port 14. After the lubricating oil is added, tighten the threaded plug 18 on the top of the oil inlet pipe 16 again. The lubricating oil that enters the interior of the cylindrical oil cylinder 9 is soaked in the lubricating roller 12 through the inclined oil hole 11. Then, in use, the inner ring 1 of the bearing drives the roller body 3 to move. The roller body 3 contacts and rubs with the outer side of the lubricating roller 12 in turn during the movement. Under the action of friction, the lubricating roller 12 rotates. At the same time, the lubricating oil soaked on the lubricating roller 12 will be coated on the outer side of the roller body 3 to lubricate the roller body 3. In this way, the roller bearing can achieve the effect of self-lubrication during use, thereby improving the wear resistance of the roller bearing and thus improving its service life.
