Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Since many rotating "axes" are used in various machines, bearings have become indispensable parts.
[0003] When existing bearings are in use, sealing covers are installed on both sides of the bearings to prevent dust from entering. As a result, the balls rotate in the bearings for a long time, which will generate higher temperatures and increase the friction coefficient, thus affecting the service life of the balls. To this end, we propose a bearing sealing structure to solve the above problem. Utility Model Content

[0009] Preferably, the supporting mechanism includes a supporting column, the inner wall of the oil filling port is fixedly connected to one end of the supporting column, and the other end of the supporting column is fixedly connected to the side of the fixing seat. By arranging multiple groups of supporting columns at equal distances on the side of the fixing seat, the fixing seat can be conveniently fixed and supported.

At this time, the lubricating oil inside the shunt oil pipe can be conveniently diverted into the bearing body through multiple sets of oil injection pipes, so that when the side of the bearing body is sealed, the ball inside the bearing body can be conveniently lubricated through the shunt oil pipe, which effectively increases the service life of the bearing body.
[0015] 2. The device can seal the inside of the oil filling port conveniently by installing the sealing top cover on the top of the oil filling port. At the same time, when oil is injected into the oil filling port, the lubricating oil can squeeze the sealing block.
