NSK bearings, NSK's main products are bearings, NSK Bearing Company, due to excellent quality and considerate service, NSK company's business is also progressing rapidly. NSK uses a well-structured intelligence network to combine the four regions of Japan, Europe, America, and Asia-Pacific into a four-pole system. Due to China's pivotal position, the development of NSK's business in China will further improve the four-pole system.


NSK bearing disassembly:


1. Disassembly of the outer ring

Remove the outer ring of the interference fit. Set several screws for extruding the outer ring on the circumference of the outer ring in advance. Tighten the screws evenly while removing them. These screw holes are usually covered with blind plugs and separable NSK bearings such as tapered roller NSK bearings. Several cuts are set on the housing shoulders. Use spacers to remove them with a press or gently tap them to remove them.


2. Disassembly of NSK bearing with cylindrical bore

The disassembly of the inner ring can be pulled out with a press machine. At this time, pay attention to let the inner ring bear its pulling force. The inner ring of large NSK bearings is disassembled by hydraulic method. Oil pressure is applied through the oil hole provided on the shaft to make it easy to draw. NSK bearings with large width are combined with the hydraulic method and drawing fixtures for disassembly operations. The inner ring of NU and NJ cylindrical roller NSK bearings can be disassembled by induction heating. The method of drawing after heating the part in a short time to expand the inner ring.


3. Removal of tapered NSK bearings

Disassemble the relatively small NSK bearing with adapter sleeve, support the inner ring with the stopper fastened on the shaft, turn the nut back several times, and use the spacer to knock it off with a hammer. Large-scale NSK bearings are easier to disassemble by oil pressure. The oil is pumped through the oil hole on the tapered shaft to expand the inner ring and disassemble the NSK bearing. During operation, there is a possibility that the NSK bearing may come out suddenly. It is better to use the nut as a stop.
