    release time:2021-04-28  viewed:608次

        Rolling needle bearing ring and rolling body, one side repeated high contact pressure, the other side has sliding rolling contact. maintainer, while sliding in contact with either side of the ring and the rolling body, or its side, suffers from tension and contraction. The information, performance and important requirements of the roller bearing ring, roller body and maintenance frame are as follows.

        Performance required for roller bearing rings and rolling data: rolling fatigue strength, high hardness, high friction, high friction

        Shelf data performance requirements: good dimensional stability, high mechanical strength

         In addition, needle roller bearings also need to have good handling capacity, according to different use, and require its impact resistance, heat resistance, erosion resistance.

        Data: the ring roller usually adopts high carbon needle bearing steel, the size of large needle roller bearing in general department, as the standard of bearing information of needle roller bearing, the chemical composition of various countries in the world has been standardized.
