• High-end bearing steel, difficult to fill the Chinese manufacturing short board

    Core technology to be overcome “High-end bearings depend on imports. Why can't we make them ourselves?” After investigating five or six provinces including the three provinces of Zhejiang, Zhejiang and Shandong, Wang Dongsheng, executive deputy director of the Shandong Technology Transformation Center of the Chinese Academy of Sciences, found the answer: the biggest problem lies in the materials. "Without good steel, you can never create high-end bearings." As an indispensable core component in mechanical equipment, the bearing supports the mechanical rotating body, reducing its friction coeff... read more

  • Breaking foreign monopoly, the high-end materials of bearings are overcome by China

    [China Machine Tool Business Network Column] Originally, Xiwang Special Steel's first batch of high-end rare earth bearing steel was successfully produced offline, and its technical performance has reached the international advanced level. The product quality has exceeded the relevant standards of the United States and Europe. The high-end rare earth bearing steel jointly built by Xiwang Special Steel and the Institute of Metals of the Chinese Academy of Sciences can solve the problem of “card neck” of high-end bearing steel technology. Another short board in the manufacturing industry was fil... read more

  • Trade Association and Bearing Association

    The Philippine International Metalworking Exhibition will debut in Manila from 22 to 25, attracting traditional industrial countries such as Germany and Japan to participate, and the Foreign Trade Association will join hands with the Bearing Association to form a total of 40 manufacturers. The trade association believes that the Philippine market has low taxes and high economic growth. However, in the past, there was a lack of an international industrial manufacturing exchange platform. It took time and time for foreign technology and machinery to enter the market. There will be new breakthrou... read more

  • Bearing repair and judgment

    When judging whether the removed bearing can be reused, check the bearing after cleaning, carefully check the condition of the raceway surface, the rolling surface, the mating surface, the wear of the cage, whether the bearing clearance is increased, and whether the dimensional accuracy is degraded. Damage, abnormality. For non-separable small ball bearings, use a one-handed flat end inner ring and rotate the outer ring to check if it is smooth. Separate bearings such as tapered roller bearings can be inspected separately for the rolling surfaces of the rolling elements and the outer ring. Lar... read more

  • Main use of outer spherical bearings

    There are two common types of outer spherical bearings: 1. outer spherical UC bearing with set screw; 2. outer spherical UK bearing with tapered bore; The outer spherical bearing is a bearing unit that combines a rolling bearing with a bearing housing. Most of the outer spherical bearing are made of spherical surface and are mounted together with the bearing housing with spherical inner hole. The structure is various, and the versatility and interchangeability are good. At the same time, these bearings are also designed with a certain degree of self-alignment, easy to install, and have a doubl... read more

  • Method for periodic inspection of outer spherical bearing failure

    After the movement period, the oscillation and noise are kept at a certain level, and the spectrum is very pure, showing only one or two times the frequency. After the outer spherical bearing went into operation, the NTN bearing oscillation and noise began to increase. Sometimes the abnormal sound was revealed, but the increase of the oscillation was less rapid. At this time, the bearing kurtness value suddenly reached a certain number. NTN bearings express late-stage fault characteristics to reveal serious faults (normal surface bearing damage such as shaft, burning, sand cracking, raceway, b... read more
