What should we notice when using miniature rod end bearings?

Miniature rod end bearings are sensitive to damage from miniature rod end bearings. For example, spalling, indentation, corrosion, cracks, abrasion, etc. are reflected in the vibration measurement of the miniature rod end bearings. Therefore, by using special miniature rod end bearings The measurer (frequency analyzer, etc.) can measure the magnitude of the vibration, and the specific case of the abnormality cannot be inferred by the frequency division. The measured value differs depending on the use conditions of the miniature rod end bearings or the position at which the sensor is mounted. Therefore, it is necessary to analyze and compare the measured values ​​of each machine in advance to determine the judgment standard.

The temperature of the miniature rod end bearings, generally the temperature of the outdoor rod end bearings, can be inferred. If the oil hole can directly measure the temperature of the outer rod end bearings, it is more suitable. Typically, the temperature of the miniature rod end bearings begins to rise as the miniature rod end bearings begin to run, reaching a steady state after 1-2 hours. The normal temperature of the miniature rod end bearings varies with the heat capacity, heat dissipation, speed and load of the machine. If the lubrication and installation parts are suitable, the temperature of the miniature rod end bearings will rise sharply, and abnormal high temperature will occur. At this time, it is necessary to stop the operation and take necessary precautions. The thermal sensor can be used to monitor the operating temperature of the miniature rod end bearings at any time, and automatically alarm or stop the occurrence of the burning shaft accident when the temperature exceeds the specified value.
