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. If the heat treatment is not in place, what impact will it have on the angular contact ball bearing manufacturer? 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 there is a problem with such a bearing, the consequences are often serious. Before, such a customer took a bearing with a broken outer ring to us to analyze the reasons. After some understanding, we learned that in order to save costs, the customer used the cheapest bearing as possible, so after the installation test, the bearing ring broke. We immediately carried out metallographic inspection on the bearing and found that the heat treatment process of the ring exists big question. Controlling the hardness is only the most basic purpose of the heat treatment process of the bearing ring. In addition to affecting the performance of the bearing, the heat treatment process also has a great impact on the fatigue life. Different wall thicknesses and different sizes of bearing rings have subtle hardness. Experienced bearing manufacturers will first strictly control the hardness after heat treatment; 37 years of experience in the production of angular contact ball bearings, the investment in equipment is relatively large, the equipment is updated relatively quickly, and the heat treatment and other processes are strictly controlled. Enterprise standards All are higher than the national standard. At the same time, precision angular contact bearings can be assembled and professionally customized according to the requirements of customers' application scenarios. The torque is accurate, in order to turn stable!
