Their main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The role of the bearing should be support, that is, literally explained as supporting the shaft, but this is only part of its role. The essence of support is to be able to bear radial loads.

[0003] The existing bearings have poor sealing performance, and the balls inside the bearings are mostly directly exposed to the outside. After long-term use, dust will enter the bearings, increasing the friction between the balls and the bearings and affecting the normal operation of the bearings. In addition, the existing bearing structure is relatively fixed, and the bearings need to be disassembled before the internal balls can be lubricated, which is not convenient for lubricating the balls. For this reason, we propose a bearing with good sealing performance. Utility Model Content

[0017] 1. For the bearing with good sealing performance, when lubricating the ball, the oil dripping port is opened by rotating the threaded seal on one side, and then oil is poured into the oil dripping port. Then the lubricating oil falls into the guide groove, and the guide groove gradually guides the lubricating oil to multiple connecting pipes. The connecting pipe transports the lubricating oil to the first mounting groove and is absorbed by the sponge strip. Then the lubricating oil in the sponge strip enters the inner ring through the oil dripping port to lubricate the ball in the inner ring. Then, the above steps are repeated to fill the oil dripping port on the other side, so that the lubricating oil can evenly lubricate the ball, so that the ball can be lubricated without disassembling the bearing, which is convenient for lubricating the ball.

After that, the threaded connecting rod is loosened to reset the reset spring squeezed by the tenon, and the tenon is pushed to penetrate the sealing ring to limit and fix the sealing ring. Then, the threaded connecting rod is rotated to screw the threaded connecting rod and the outer ring to complete the installation of the sealing ring. Repeat the above steps to install the sealing ring on the other side so that the sealing ring can seal the bearing ball to prevent dust from entering, thereby effectively increasing the sealing performance of the bearing and improving the working stability of the bearing.
