The bearing comprises a bearing inner ring 10, a bearing outer ring 11, balls 12, a positioning ring 13, an outer sealing double ring 14, a connecting ring 15, an outer clamping slip ring 16, an oiling channel 17, a balancing weight 18, an inner clamping slip ring 20 and an inner sealing ring 21.

Detailed Description

The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.

As shown in fig. 1, 2 and 3, the sealed bearing of the present embodiment includes a bearing inner ring 10, a ball 12 is slidably connected to the outer side of the bearing inner ring 10, a bearing outer ring 11 is slidably connected to the outer side of the ball 12, and a sealed lubrication assembly is disposed between the bearing outer ring 11 and the ball 12, and the sealed lubrication assembly can seal and lubricate the inside of the bearing when the bearing works, and supplement oil when the internal oil leaks.
