Description

Technical Field

[0002] In the prior art, during the use of vertically placed sealed bearings, foreign impurities often enter the interior of the bearings or the grease inside the bearings leaks, which often leads to an increase in the friction loss rate of the rollers or steel balls in the bearings. In particular, for bearings that have been running for a long time, the failure to replenish the internal grease will greatly reduce the life of the bearings and further affect the working efficiency of the bearings. After long-term operation, the internal grease of the bearings is completely consumed, the wear rate of the steel ball surface increases, and the rolling direction of the steel balls is easily misaligned, which affects the use of the bearings and further reduces the working efficiency of the bearings.
