我厂生产的双列短圆柱滚子轴承过去都采用铜保持架。不仅因为铜是一种重要的国防物资,应当节约;而且铜保持架加工复杂,材料利用率抵,成本高。因此,我们遵照伟大领袖毛主席关于“备战、备荒、为人民”和.“要采用先进技术,必须发挥我国人民的聪明才智,大搞科学实验。”的教导,努力研制塑料保持架,并扩大其应用范围。 I double-row cylindrical roller bearings produced in the past are used copper cage. Not only because copper is an important defense material, it should be saved; moreover, copper cage processing is complicated, material utilization rate is high and costs are high. Therefore, in accordance with the teachings of Chairman Mao, the great leader, on “preparing for war, preparing for war, for the people,” and “adopting advanced technologies, we must make full use of the wisdom and wisdom of our people and make scientific experiments.” Frame, and expand its scope of application.
