Spindle motor and high-speed electric spindle are noisy, don't just replace the bearings anymore! (37 years of experience in bearing manufacturers) -

Bearings are key components in high-speed spindle motors. Now that high-speed construction machinery motors are widely used, bearings often produce some noise during use. For this type of noise, many motor operators will have such a problem: bearings What is the reason for the noise, do you need to replace a new bearing. For this kind of problem, Sanli, as a manufacturer of spindle motor bearings for 37 years, will tell you today. Many people think that the noise of bearings should be mainly due to some problems with the bearings, so when encountering bearing noise problems, many people directly replace a new bearing. Although this is a solution, it is actually not necessary sometimes. buy new ones. In addition to judging whether there is noise, the bearing to be replaced should also be determined according to the service life and damage of the bearing. It is not necessary to replace the bearing as soon as there is noise. Generally speaking, high bearing noise is not the cause of bad bearings. When the spindle motor runs at high speed during use, the bearing is very important; the bearing is the most important component for the high-speed operation of the spindle motor. There is abnormal noise in the bearing, which is generally due to the lack of lubricating oil in the bearing. It’s just that the sound is partial, and the bearing has no other abnormalities, so it is not necessary to replace the bearing at this time. It is necessary to increase the amount of circulating water to improve the actual cooling effect. It is best not to run for a long time. It is better to slow down and cool down during the work . However, if the bearing vibrates violently during operation, it means that the bearing is seriously damaged, and the bearing needs to be replaced even if there is no noise. Sanli high-speed electric spindle bearings have the characteristics of compact structure, light weight, small inertial force, small vibration, low noise, fast response, etc., and have many advantages such as high speed and high power, and have become more and more popular in the application field of CNC lathes. more common. Undertake the design and manufacture of various high-speed electric spindles/spindle motors/high-speed motors, as well as the production and customization of various high-speed electric spindle bearings, spindle motor bearings, and high-speed motor bearings from all over the world. Only when the torque is accurate can the rotation be stable!
