As an industrial product, angular contact ball bearings have manufacturers at home and abroad. Why is there such a big gap between the production process levels of different angular contact ball bearing manufacturers for an ordinary small bearing? There is not much difference in the technology of heat treatment, the selection of raw materials, the degree of automation, etc., but the quality is uneven, so what are the difficulties in the production of angular contact ball bearings? In fact, our old master who has been producing bearings for 37 years told you that the difficulty of bearing manufacturing lies in controlling the bearing clearance. Many people think that the bearing clearance is determined during the assembly process, but in fact, the bearing clearance is in the production and assembly process. The accuracy of the inner ring, outer ring and steel ball of the bearing is very important to the accuracy of the bearing clearance. If there is a problem with the same accuracy, the accuracy of the bearing will be greatly affected, and the clearance The gap will not be very accurate. Of course, while the production and assembly process is very important, the raw material itself is also a very important factor. The wear resistance and overall level of the raw material itself also determine the quality of the bearing. If an angular contact ball bearing manufacturer can strictly control the raw materials, heat treatment process, manufacturing process and assembly technology of the bearing, then it is bound to be able to manufacture a good bearing. The torque is accurate, in order to turn stable!
