Precautions When Using WSBC Bearings


     1. Selection of shaft and bearing and tolerance of control room

Press-in bearings WSBC bearings should be flexible without blocks in the direction of rotation. If the rotation is significantly inflexible, the size of the shaft is too large. As the tolerance of the shaft is obviously "sandy" after turning it by hand, it may be too poor or the roundness of the shaft. Therefore, a good shaft and bearing control room should also be controlled within the roundness tolerance.


     2. WSBC bearing assembly method

Because WSBC bearings are precision products, such as improperly assembled channels, it is easy to damage WSBC bearings, and WSBC bearings can cause damage. When assembling the WSBC bearing, there should be a special mold, which cannot hit people. The pressure when entering the shaft can only be a small circle, which is only cycled by force. Large bearings will require pneumatic or hydraulic pressure. The pressure during use is installed on the upper and lower molds in a horizontal state. If the WSBC bearing channel is inclined, it will cause damage to the power and cause the bearing to cause the WSBC bearing.


     3. Prevention of assembly foreign matter

When installed in the rotor dynamic balance, it is easy to generate iron chips into the WSBC bearing to dynamically balance the WSBC bearing, so it is best to balance the WSBC bearing before loading. There are also some manufacturers in order to facilitate assembly, in the internal coating with some oil or grease lubrication, but the operator bearing assembly is often difficult to control the amount, if the oil or grease in the large indoor WSBC bearings, WSBC bearings accumulate along the axis When, it is easy to enter the WSBC bearing to rotate.


     4. Anti-rust paint

The characteristic of paint rust is that multiple motors sound good in a sealed assembly motor, but after a period of time in the warehouse, the motor becomes very abnormal sound, except for the severe rust of the WSBC bearing. The manufacturer will be regarded as the former WSBC bearing problem. Through our continuous publicity, we have now realized that the main electrical factory is the problem of insulating paint. The main problem is that the insulating varnish volatile acid is formed at a certain temperature, humidity, and corrosive substances, leading to corrosion damage in the WSBC bearing channel. The only problem now is to choose a good varnish and assemble the air after drying for a while. Wuxi Spark Bearing Co.,Ltd provides WSBC 23122-2CS, click here for more details.

The effect of cleanliness on the performance of WSBC bearings:


    1. The impact on the life of WSBC imported bearings

    The cleanliness of imported WSBC bearings has a considerable impact on the life of the bearings. Special tests have been carried out on imported WSBC bearings. The result is that the difference is several times or even dozens of times. The higher the cleanliness of WSBC imported bearings, the longer the life expectancy. Tests by others have shown that lubricating oil with different cleanliness has a great impact on the life of NTN imported bearings. Therefore, improving the cleanliness of the lubricating oil can extend the life of imported WSBC bearings. In addition, if the lubricating oil contains dirt particles below 10um, the life of the bearing will also increase several times.


    2. Impact on vibration and noise

    (1) Impact on vibration The test results of the WSBC imported bearing test center show that cleanliness seriously affects the vibration level of the bearing, especially the high-frequency vibration is more significant. Imported WSBC bearings with high cleanliness have low vibration speed values, especially in high frequency bands.

    (2) Impact on noise The test has been conducted on the impact of dust in WSBC imported bearing grease on noise, and it is proved that the more dust, the greater the noise.


    3. Impact on lubrication performance The decrease in cleanliness of imported WSBC bearings not only affects the formation of lubricating oil film, but also causes the deterioration of the grease and accelerates its aging, thereby affecting the decline of the lubricating performance of the grease.WSBC 23130-2CS online, click here to buy it.

   The quality of anti-rust materials directly affects the quality of product processing. Therefore, when selecting anti-rust materials, first perform physical and chemical performance testing according to the quality requirements, and then conduct a pilot test if they meet the process requirements. The selected anti-rust auxiliary materials are strictly tested according to the quality standards of different materials after entering the factory, and they can be issued and used by the supply department after they are qualified. In the process of use, the anti-rust materials and the prepared solution are tested regularly to ensure that the concentration and ratio of the solution meet the process requirements and achieve the performance. The establishment of a complete material acceptance system and quality acceptance standards provides a reliable guarantee for doing a good job in anti-rust management.


   Cooling water mainly plays multiple roles in WSBC bearing processing, such as cooling, lubrication, cleaning, and rust prevention. Its correct use and maintenance directly affect the surface quality of machined parts and the service life of tools. The cooling water used in WSBC bearings can be roughly divided into three types: soda water, emulsion and synthetic grinding fluid. Basically, the tank liquid of more than 50 tons is used in a large cycle. The washed grinding product grinding wheel powder, iron dust and oil It is easy to cause the cooling water to deteriorate and cause burns and rust of the processed parts. Strengthening the scientific management of cooling water can improve its performance, ensure product quality, and reduce the cost of cooling water.


   After washing the product, immerse it in a solution containing 15%-20% sodium nitrite and 0.6% sodium carbonate, and then stack it. Using this method, the anti-rust period is relatively short, generally only 7-14 days, and in the rainy season, due to the wet weather, it can only be maintained for 2-3 days and must be reprocessed, which requires labor and money.


   The WSBC bearing ring is immersed in an aqueous solution of 5% sodium nitrite and 0.6% sodium carbonate. The anti-rust effect is good, but it requires many anti-rust tanks and other equipment, which takes up a lot of space and is inconvenient to manage.
