During the operation, the oil should be heated to 100 degrees Celsius, and then the oil should be poured on the needle roller bearing to be disassembled. The operation steps of each disassembly method of needle roller bearings are different, how to master them one by one? The first thing I saw is the percussion method of needle roller bearings. Generally, when the needle roller bearing is disassembled by percussion method, the percussion force mainly acts on the inner ring of the bearing, and cannot be applied to the rolling elements and cage of the bearing. Next is the thermal disassembly method to disassemble the needle roller bearing. Of course, the reasonable selection of the puller is also very important, otherwise it will not be possible to do it no matter how hard it is.Since there are many different installation methods for needle roller bearings, naturally there are also different disassembly methods. Therefore, you must be very careful when disassembling the needle roller bearing, and you must not knock it at will to avoid unnecessary problems. Compared with the above two disassembly methods, the push method is more stable and reliable to disassemble the needle roller bearing. It uses a press to push the bearing, Mechanical roller bearings so that it will not cause damage to the machine, and the needle bearing can maintain good integrity . The more common ones include percussion method, thermal disassembly method, push method and pull method. That is to say, the key to this disassembly method is to find the focus point and place the cushion block appropriately. After the bearing ring is heated and expanded, the bearing can be moved with a puller Pulled out, it is also easy to operate. Although this method of operation is relatively simple to implement, it is easy to damage the bearing if you are careless.Then there is a pull-out method, using this method to disassemble requires a special puller, as long as the handle of the puller is selected, the bearing can be pulled out slowly
