Many people will ask what are the conditions for paired bearings? What is the difference between universal matching and matching bearings? This article is about to ask you to answer. The life of angular contact ball bearings is related to the load force of the bearing. When the radial load is too large, we often use two bearings in series to increase the load. However, in this way, because the bearing height and orientation tolerance is relatively large, the bearing force will be affected. Therefore, when 2 bearings must be applied together, it is strongly required to use paired bearings! So what are the solutions for matching bearings in different scenarios? 1. The imported bearings use universal matching bearings; the imported bearings usually adopt the universal matching method. The advantage of this method is obvious, that is, it is easy to assemble. But the drawbacks are also very significant, because the production and processing regulations are particularly high, so the price is higher, and it is more suitable for some high-end application scenarios. Second, the more economical solution: use paired bearings. The matching suffixes are DB, DF, and DT, respectively. This is a more economical solution. For 37 years, we will provide you with angular contact ball bearing matching solutions according to customer application scenarios, professional customization. The torque is accurate, in order to turn stable!
