Rolling bearing rings and rolling elements, while repeating high contact pressure, one side with a sliding contact with the sliding. Maintainer, one side with the ferrules and rolling body on both sides, or one of its sliding contact, one side by the tension and contraction. Therefore, the bearing rings, rolling elements and maintenance of the information, performance, important requests are as follows. The following are the same as the "
    Rings, rolling information requested by the performance: rolling fatigue strength of high hardness and high wear resistance of high-dimensional stent data requested by the performance: dimensional stability of good mechanical strength, in addition, also need good processing. According to the use of different, but also requested its impact resistance, heat resistance, good corrosion resistance. The following are the same as the "
    Ferrule and rolling material: ferrule and rolling body is usually the use of high-carbon chromium bearing steel. Most of the bearings, the use of JIS steel in the SUJ2. Large bearings use SUJ3. SUJ2 chemical composition, in the world, as a sliding bearing with the data has been standardized. For example: and AISL52100 (US), DIN100Cr6 (West Germany), BS535A99 (UK), etc. are the same kind of steel. The following are the same as the "
    Further need to impact the situation, as the bearing material using chrome steel, chrome molybdenum steel, nickel chrome molybdenum steel, take carburizing quenching, so that steel from the appearance to the appropriate depth of a softening layer. With appropriate softening depth, fine organization, suitable for the appearance of hardness and hardness of the carburizing bearing, than the use of bearing steel bearings with excellent impact resistance, the individual carburizing bearing steel chemical composition. The following are the same as the "
    NSK implemented a vacuum degassing solution, so the use of information cleanliness, oxygen content, good quality. And then take the appropriate heat solution, so that the rolling bearing life expectancy significantly improved. The following are the same as the "
    In addition to the above-mentioned steel, according to the special use, but also the use of high heat resistance of high-speed steel, good corrosion resistance of stainless steel. The following are the same as the "
    Maintenance information: stamping the cage of the information, the use of low carbon steel. According to the use of different, but also the use of brass plate, stainless steel plate. Cut the material of the cage, the use of high-strength brass, carbon steel, in addition to the use of decomposition resin.
