Assembly mark and assembly method of universal combined bearing (SU)
Universal Combination Table 3 Bearing Combinations and Codes Angular Contact Ball Bearing Combinations and Code Remarks: Page A156 [Supplementary Codes of Bearings Used] is excerpted to make the same type of bearings, no matter how the combination can achieve the set preload, and During manufacturing, the width difference between the front and back is controlled and made equal, which is the universal combined bearing. At this time, in order to avoid mistaking the bearing installation direction and get the correct combination method, a V-shaped mark is made on the outer ring outer diameter of a single bearing. The direction of the arrow tip of the V-shaped mark indicates the direction of the axial load (contact angle) screwed on the inner ring. Front width difference f u003d back width difference b Therefore, it is suitable for various combinations. DB combination back width difference×2u003d2b(u003d2f) can get the set pretension force DF combination front width difference×2u003d2f (u003d2b) can get the set pretension force DT combined front width difference f u003d Backside width difference b, there is no clearance between DT as the usual DT combination. HPS angular contact ball bearing HPS angular contact ball bearing has better load capacity, higher limit speed and accuracy. Take the universal combination as the standard. (a) By extending the service life, it helps to reduce the operating cost of industrial machinery. By optimizing the internal design of the bearing and the unique material technology, the bearing life is 90% longer than the original product. Therefore, it helps to reduce maintenance frequency and operating costs. In addition, in the case of the same set life, the miniaturization of the bearing is realized, which helps to realize the miniaturization and energy-saving design of the machine. (b) By increasing the limit speed, it is helpful to realize the high speed of industrial machinery. By optimizing the internal design of the bearing and precision machining and manufacturing technology, the limit speed of the bearing has been increased by 15%-20% compared with the original product. Therefore, the speed of industrial machinery can be increased, which contributes to the improvement of work efficiency. (c) The universal combined bearing is used as a standard inventory, which is convenient for precise positioning. Precision machining and manufacturing technology are adopted. The bearing rotation accuracy reaches P5 level and the dimensional accuracy reaches P6 level. Angular contact ball bearings can be freely combined to facilitate precise positioning. Therefore, it is convenient for the assembly and maintenance of industrial machinery, and at the same time helps to achieve high efficiency of the machinery. (d) There are 3 kinds of cages suitable for different purposes, which help to improve the reliability of industrial machinery. There are 3 types of cages to choose from: nylon 46 plastic cage with excellent high temperature strength (photo 1), L-PPS plastic cage with excellent oil and chemical resistance (photo 2), and high-reliability copper alloy car holder Frame (photo 3). Therefore, the bearing helps to improve the reliability required by various industrial machinery.
