A plurality of ventilation holes 9 are provided on the upper and lower wall sides of the outer sleeve ring 1 to increase the bearing capacity. The contact area between the body and the air can improve the heat dissipation effect of the device to a certain extent. The lubricating oil placement groove 7 can be filled with lubricating oil by welding the cylinder 1001, and the plug 1002 is connected and sealed. Then the internal fixed block 1101 is connected to the adjusting spring 1102 to support the slider 1103 in the cylinder. The slider 1103 in the cylinder limits the position of the lubricating oil at the top. During the use of the bearing, under the action of the rotating centrifugal force and the vibration of the equipment, the slider 1103 in the cylinder can squeeze the adjusting spring 1102 to move inside the lubricating oil placement groove 7, so that the lubricating oil flows out from the through hole 8 and enters the inside of the bearing. While lubricating the device, it can also absorb part of the heat and reduce the loss of the bearing to high temperature.
