There are many ways to install the roller slider, of course, there are different ways to disassemble it. The more common way includes four ways: Hot disassembly, pushing and pressing, knocking and dragging.

The operation process of each disassembly and assembly method of cylindrical roller bearing is all different, so how to grasp today's net editing and teaching group?

① In the case of knocking method and disassembling roller standard bearing, the key effect of knocking force is in the inner hole of rolling bearing, but it can not be added into the turnover body and maintenance wall of rolling bearing. In other words, the key to this type of disassembly and assembly is to select the most important part, and the place where the protective layer cushion block is placed should be appropriate. Although this kind of operation procedure is very simple to carry out, it is very easy to destroy the rolling bearing if you don't pay attention to it. Therefore, when disassembling the cylindrical roller bearing, you must be very careful. You can't knock it at will to prevent redundant problems.

② In the process of hot disassembly and disassembly of professional roller bearings, the motor oil should be heated to 100 ℃ in actual operation, and then the motor oil should be irrigated to the cylindrical roller bearing to be disassembled, until the rolling bearing ring is heated and deformed, the roller bearing can be pulled out with puller, which is also very easy for practical operation.

③ The method of pushing and dismounting cylindrical roller bearing is relatively stable and reliable. It is used to push and press the rolling bearing by the press, which is not easy to cause damage to the equipment, and the cylindrical roller bearing can maintain stable consistency.

④ Pull out method. Professional puller must be selected for disassembly and assembly in this way. If the rocker of puller is selected, the rolling bearing can be pulled out gradually. Naturally, the effective use of pullers is very important, otherwise no matter how hard it takes
