The disassembly of the bearing is a regular maintenance and Bearing 6704-2RS FBJ is performed when the bearing is replaced. After dismantling, if you continue to use, or need to check the state of the bearing Bearing 6704-2RS FBJ, its dismantling must be performed as carefully as during installation. Be careful not to damage the parts of the bearing, especially the disassembly of the interference fit bearing, it is difficult to operate.
is also important to design and manufacture disassembly tools as needed. When disassembling, according to the drawings, study the disassembly method, sequence, and investigate the matching conditions of the bearings so as to obtain the completeness of the disassembly operation.
The outer ring is fitted with an outer ring that is fitted with an interference fit. Several screws Bearing 6704-2RS FBJ are arranged on the outer circumference of the outer shell to compress the screw in advance, and the screw is tightened on one side and removed. These screw holes are normally covered with blind plugs. Separate bearings Bearing 6704-2RS FBJ, such as tapered roller bearings, are provided with several cutouts on the housing blocking shoulders. The pads are used to remove them with a press or to tap gently for disassembly.
The removal of the inner ring of Bearing 6704-2RS FBJ can be pulled out by the press the easiest. At this point, pay attention to the inner ring to withstand its pulling force. Furthermore, the illustrated pull tabs are also used mostly, and regardless of the kind of clip, they must be firmly stuck on the side of the inner ring. For this reason, it is necessary to consider the size of the shaft stopper shoulder, or to study the processing of the upper groove at the stopper shoulder in order to use the drawing jig.
The inner ring of a large-sized bearing is disassembled by hydraulic method. Oil pressure is provided through the oil hole in the bearing to make it easy to pull. For bearings Bearing 6704-2RS FBJ with a large width, the oil pressure method is used in conjunction with a pull fixture to perform the disassembly operation.
Inner ring disassembly of cylindrical roller bearings can use induction heating. Heating in a short time, so that the inner ring expansion after the method of drawing. If you need to install a large number of these types of bearing inner rings, induction heating is also used.
