Why are there so many bearing manufacturers, but the bearing products are uneven? That is because many bearing manufacturers ignore many links in the production process, resulting in problems such as insufficient precision and short service life of bearings during use. So what operations of these bearing manufacturers will reduce the quality of bearings? The editor summarizes a few points for you: 1. Many bearing manufacturers reduce the cost of raw materials to improve competitiveness; in order to reduce costs and increase competitiveness, some bearing manufacturers blindly pursue low prices and choose the cheapest bearings possible. To meet their needs, some bearing manufacturers will choose low-quality and low-cost raw materials, which may not cause problems in the short term, but if used for a long time, the reliability of the bearing will be poor, which will easily lead to the failure of the spindle. 2. Bearing manufacturers do not pay attention when assembling, there are impurities and small particles; during the assembly process, if there are small particles such as dust entering, it is likely to affect the performance of the spindle, thereby reducing the machining accuracy of the equipment. It is easy to cause friction and heating of the main shaft, and it will fail in advance, and the selection of bearings with higher precision can alleviate this phenomenon to a certain extent; 3. The main shaft seal is unreasonable, and the quality of the seals is not good; if the design of the main shaft seal is unreasonable, or the quality of the seals is not up to standard , not only can not achieve the original sealing effect, but also may affect the performance of the spindle, thereby reducing the processing capacity of the equipment; if the working environment of the spindle is relatively bad, I recommend the use of a sealed spindle bearing, which can further improve the spindle The sealing performance is more effective to prevent the entry of liquid or dust; 4. The injection method of grease by the bearing manufacturer. High-end bearing manufacturers will use advanced grease injection equipment when injecting grease into bearings, which can ensure that the amount of grease injected into the bearing is within the most reasonable range, and the grease injection will be more uniform. Small particles such as dust are mixed with dust, and the grease injection process should be carried out in a dust-free environment as much as possible; 37 years of experience in bearing manufacturers, strict control from all aspects of bearing production, to create high-standard, long-life, high-precision, high-quality products for you.
