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 the bearings during use. So what operations of these bearing manufacturers will reduce the quality of the bearings? The editor summarizes a few points for you: 1. Many bearing manufacturers reduce raw material costs to improve competitiveness; In order to reduce costs and increase competitiveness, some bearing manufacturers blindly pursue low prices and choose bearings that are as cheap as possible. To meet their needs, some bearing manufacturers will choose low-quality and low-priced raw materials, which may not cause problems in the short term, but if used for a long time, the reliability of the bearings will be poor, and it is easy to cause the spindle to fail. 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 processing accuracy of the equipment. It is easy to cause frictional heating of the main shaft and premature failure, 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 seal is not good; if the design of the main shaft seal is unreasonable, or the quality of the seal is not up to standard , not only cannot achieve the original sealing effect, but also may affect the performance of the main shaft, thereby reducing the processing capacity of the equipment; if the working environment of the main shaft is relatively harsh, I recommend choosing a main shaft bearing with a seal, which can further improve the main shaft Excellent sealing performance, more effective to prevent the entry of liquid or dust; 4. The bearing manufacturer's injection method for grease. High-end bearing manufacturers will choose advanced grease injection equipment when injecting grease to the bearings, which can ensure that the amount of grease injected into the bearings is within the most reasonable range, and the grease injection will be more uniform. In addition, in order to avoid grease Dust and other small particles are mixed, and the grease injection process should be carried out in a dust-free environment as much as possible; Sanli has 37 years of experience in bearing manufacturers, and strictly controls all aspects of bearing production to manufacture high-standard, long-life, and high-precision bearings for you. , Torque-accurate bearings!
