Any angular contact ball bearing manufacturer who has rich experience in bearing production will know that the heat treatment process of the bearing is a very important link for the bearing, so if the heat treatment is not in place, what kind of impact will it have on the manufacturer of angular contact ball bearings? The heat treatment process is not up to standard, the bearing structure is unstable, and the customer cannot distinguish it with the naked eye. Once such a bearing has a problem, the consequences will often be more serious. There was such a customer before who brought us a bearing with a broken outer ring to analyze the reason. After some understanding, we found out that in order to save costs, the customer used as cheap a bearing as possible. As a result, after the installation test, the bearing ring broke. We immediately carried out a metallographic inspection on the bearing and found that the heat treatment process of the ring was defective. Big question. Controlling the hardness is only the most basic purpose of the heat treatment process of the bearing ring. The heat treatment process not only affects the performance of the bearing, but also has a great impact on the fatigue life. Different wall thicknesses and different sizes of bearing rings have subtle differences in the appropriate hardness. Experienced bearing manufacturers will first strictly control the hardness after heat treatment; 37 years of angular contact ball bearing production experience, relatively large investment in equipment, relatively fast equipment update, strict control of heat treatment and other processes, enterprise standards All of them are higher than the national standard. At the same time, we can assemble precision angular contact bearings according to the requirements of customers' application scenarios and customize them professionally. Only when the torque is accurate can the rotation be stable! (/xjrcld.html)
