NSKHPS angular contact ball bearings have better load capacity, higher limit speed and accuracy. The universal combination is the standard. (a) Helps reduce the operating cost of industrial machinery by extending the service life. By optimizing the bearing internal design and unique material technology, the bearing life is extended by 90% compared with the original product. Therefore, it helps to reduce maintenance frequency and running cost. In addition, under the condition of the same set life, the miniaturization of the bearing is realized, which contributes to the miniaturization and energy saving design of the machine. By increasing the limit speed, it is helpful to realize the high speed of industrial machinery. By optimizing the internal design of the bearing model 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-up of the industrial machine is realized, thereby contributing to the improvement of the work efficiency. The universal combined bearing is used as a standard inventory, which is convenient for precise positioning. Precision machining and manufacturing technology are used. The bearing rotation accuracy reaches P5 level, and the dimensional accuracy reaches P6 level. The angular contact ball bearings can be freely combined, which is convenient for precise positioning. Therefore, industrial machinery assembly and maintenance are facilitated, while contributing to the realization of high efficiency of the machinery. There are 3 kinds of cages suitable for different purposes, which help to improve the reliability of industrial machinery. NSK has 3 kinds of cages to choose from: nylon 46 plastic cage with good high temperature strength (photo 1), oil resistance, chemical resistance Excellent L-PPS plastic cage (photo 2) and high reliability copper alloy machined cage (photo 3). Therefore, the bearing contributes to the reliability required for various industrial machines.
