The Metric Rod End Bearings is a branch of the rod end bearing. In practical applications, this type of bearing belongs to a rod bearing or a rod end bearing. It should be noted that the vibration of the Metric Rod End Bearings is sensitive to its damage. For example, flaking, indentation, rust, crack, and wear are all reflected in the vibration measurement of the rod end joint bearing.
Therefore, during use, the vibration of the Metric Rod End Bearings can be measured by a dedicated rod end joint bearing vibration measurer, and the frequency can be used to infer abnormal conditions. However, the measured values are generally different because of the use conditions of the rod end joint bearing or the installation position of the sensor. Therefore, before use, it is necessary to analyze and compare the measured values of each machine to determine the criteria.
For the operating state of the Metric Rod End Bearings, it can also be judged by the temperature change. It is usually based on the temperature outside the rod end of the rod bearing. It is more appropriate if the oil hole can directly measure the temperature of the outer ring of the rod end. Under normal circumstances, its temperature will gradually increase with the extension of operating time, and will reach a stable state after running for an hour or two.
In addition, the normal temperature of the Metric Rod End Bearings will change due to some factors, such as the thermal capacity of the machine, heat dissipation, speed, and load. If it is not properly lubricated and installed, its temperature may rise dramatically. At this time, it is necessary to immediately stop the operation and take necessary measures to ensure safety.
According to the characteristics of the Metric Rod End Bearings, it is mainly applied to a support location where the concentricity is generally required and the working surface pressure is relatively large, and the swinging and rotating motion is performed at a slow speed. Metric Rod End Bearings are widely used in engineering hydraulic cylinders, construction machinery, forging presses, automation equipment, automotive shock absorbers and hydraulic machinery and other industries.
