Have you heard of nsk bearings? Nsk bearings , nsk's main products are bearings, nsk bearing companies, due to excellent quality and good service, nsk's business has also been rapid development. Nsk uses a well-structured intelligence network to combine four regions of Japan, Europe, the Americas, and Asia Pacific into a four-pole system. Due to China's decisive position, the development of nsk's career in China will further improve the quadripolar system. Today we are going to introduce you to a bearing brand - nsk bearings . Today we want to bring you is nsk bearing price, nsk bearing installation and maintenance knowledge.

Nsk bearing introduction

NSK Bearings is committed to building a comfortable and safe society through the "MOTION&CONTROL" technology. CHALLENGERS will also be able to access the Internet and open market intelligence to nsk distributors around the world. Nsk's global electronic logistics system will enter the new era of the network synchronously with the times. NSK Bearings does not meet the industry's leading position in Japan, but has long since turned its sights on overseas markets. After more than 20 years of painstaking efforts, nsk has established mature production, development and sales mechanisms in developed Europe and the United States. In the Asia-Pacific region, nsk's business is also making rapid progress due to its excellent quality and considerate service. In these major world markets, nsk uses a well-structured intelligence network to combine four regions of Japan, Europe, the Americas, and Asia Pacific into a four-pole system. With the continuous development of the nsk bearing industry, more and more industries and enterprises have applied to nsk bearings, more and more companies have entered the nsk bearing industry and are widely used: construction machinery, machine tools, automobiles, metallurgy, mining, petroleum, Machinery, power, railway and other industries.

With the arrival of the globalization of nsk, many domestic companies have started to engage in nsk bearing agency business, but because many agents do not have a certain knowledge of bearing knowledge, there are still many problems in customer marketing, including technical support. Therefore, in the direction of nsk global development, we must pay attention to the normalization of nsk globalization. Manage and train to the level required by a professional nsk company.

Nsk bearing installation:

1. Before installing the imported bearing on the shaft, the fixing pin of the bearing housing must be unplugged, and the surface of the journal should be smooth and clean, and the journal should be oiled with rust prevention and lubrication (allowing the bearing to rotate slightly on the shaft).

2. Lubricate the bearing seat and the bearing mating surface and install the bearing into the bearing seat. Then put the assembled bearing on the shaft together with NSK bearing. Push to the desired location for installation.

3. Do not tighten the bolts securing the bearing housing. Allow the bearing housing to rotate within the housing. Also install the other end bearing and seat on the same shaft, rotate the shaft a few times, and let the bearing itself automatically align the position. Then tighten the bearing seat bolts.

4. Eccentric sleeve. Firstly, the eccentric sleeve is sleeved on the eccentric step of the inner sleeve of the bearing and tightened by hand along the rotation direction of the shaft. Then insert or hold a small steel rod against the countersink on the eccentric sleeve. 3. Tap the small steel bar with the hammer in the direction of rotation. Make the eccentric sleeve securely, and finally lock the hexagon socket screw on the eccentric sleeve.

Nsk bearing disassembly:

1, the demolition of the outer ring

To disassemble the outer ring of the interference fit, screw the screw of the outer ring extrusion screw on the circumference of the housing in advance, and tighten the screw equally while disassembling. These screw holes are usually covered with blind plugs, nsk bearings such as tapered roller bearings, etc., in the shell shoulder set several incisions, use the pads, use a press to disassemble, or tap gently to disassemble.

2, cylindrical hole nsk bearing disassembly

The disassembly of the inner ring can be pulled out by the pressure and mechanically the latest and simple. At this point, pay attention to the inner ring to withstand its pulling force. The inner ring disassembly of large nsk bearing adopts hydraulic method. Oil pressure is provided through the oil hole provided on the shaft to make it easy to pull. NSK bearing with a large width is used together with drawing fixtures for oil removal and disassembly. The inner ring disassembly of NU type, NJ cylindrical roller nsk bearings can use induction heating. Heating in a short time, so that the inner ring expansion after the method of drawing.

3, the removal of the tapered hole nsk bearing

Remove the relatively small nsk bearing with an adapter sleeve. Support the inner ring with a block that is fastened on the shaft. After turning the nut back several times, use the pad to knock it out with a hammer. Large-sized nsk bearings are easier to dismantle with oil pressure. They are pressurized in the oil hole in the bore hole shaft to expand the inner ring and remove the nsk bearing. In operation, there is a possibility that the nsk bearing may suddenly come out. It is better to use the nut as a stopper.

  

Nsk bearing maintenance

1. Maintain nsk bearing lubrication and clean

Before inspecting the nsk bearing, the surface of the nsk bearing should be cleaned before disassembling the peripheral parts of the nsk bearing. It must be noted here that the oil seal is a very fragile part, so nsk bearings must not be excessively stressed during inspection and dismantling so as to avoid damage to the parts. If the nsk bearing oil seal and its surrounding parts have been showing bad symptoms, please be sure to replace it, so as not to cause a bad oil seal will lead to nsk bearing damage.

2.nsk bearing lubricant quality.

A lot of later found nsk bearing life is too short, found that in addition to other factors normal, everyone knows that the quality of the lubricant is also directly affected. About nsk bearing lubricant inspection method is: touch with a little bit of lubricant friction between the two fingers, if there is a contaminant, it can be felt; or a thin layer of lubricant on the back of the hand, and then sealing inspection . Then is to replace the nsk bearing lubricant. Note: It is best to filter the oil before use. When using grease-lubricated nsk bearings when replacing grease, the jostle cutters used should avoid any parts of the nsk bearing with cotton joints. Because these residual fibers may be wedged between the rolling elements and cause damage, especially the application of small bearings requires more attention to this problem.

3.nsk bearing working environment.

When checking nsk bearings, do not expose them to contaminants or moisture. If the work is interrupted, the machine should be covered with a plastic sheet or similar material. The working environment of the bearing is also very important. In many machines, the imported bearings are not working because of the working environment, which leads to the end of the life of the imported bearings.
