Main troubleshooting aspects of regular bearing maintenance

In terms of bearing speed, the bearing is determined according to the type, size, accuracy, cage type, load, lubrication mode, cooling mode and other factors.
The bearing can be disassembled and installed as required in specific occasions to ensure that it can be disassembled and installed as required. Bearings with separate inner and outer rings, such as cylindrical bearings, needle roller bearings and conical bearings, are very suitable for this occasion. With the help of the shaft sleeve, the installation procedure of the taper hole type self-aligning ball bearing and self-aligning roller bearing is also simplified.
In some cases, preloading shall be applied to the rolling bearing to increase the rigidity. This procedure is usually used for the offset of the inner and outer rings of deep groove ball bearing, centripetal thrust ball bearing and tapered roller bearing, shaft bending, the change of tolerance of shaft or bearing housing, and matching error will lead to the eccentricity of the inner and outer rings. In order to prevent excessive eccentric angle, self-aligning ball bearing, self-aligning roller bearing, or self-aligning bearing seat are better choices. Voice frequency and torque, dynamic bearings are manufactured according to high-precision standards, so voice and torque are small. Deep groove ball bearings and cylindrical roller bearings are used for occasions with special requirements for low noise and low torque.
(1) Note that the bearing with seal can not be cleaned by this method, and the inside of the seal should be kept as it is.
(2) The assembly surface shall be cleaned with clean gasoline, kerosene, toluene or xylene solution, wiped dry with a clean rag, and then coated with a thin layer of smooth oil, so as to make the operation of the device convenient and efficient.
(3) When facing the device, open the bearing package, immerse it in the above gasoline and other liquids, and rotate it gently by hand. Ensure that the sealing oil on the surface of the holder, rolling element and raceway is completely cleaned.
(4) When cleaning a large number of bearings, first pour hot engine oil with a temperature of 90 ~ 100 ℃ to condense the sealing oil. At the same time, dig out all the old oil with a seamless tool without chips, then pour hot for a few minutes, then wash the oil with kerosene, and finally wash it with gasoline. After cleaning, wear film gloves and put the bearing on a clean cloth or paper on the workbench to dry.
