• 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

  • What are the basic characteristics of the outer spherical bearing?

    The outer spherical ball bearing is actually a variant of the deep groove ball bearing. Its characteristic is that its outer ring outer diameter surface is spherical, which can be fitted into the corresponding concave spherical surface of the bearing seat to play the role of centering. Although its basic performance should be similar to that of deep groove ball bearings, most of these bearings are used in relatively rough machines, the mounting position is not accurate enough, the axis of the shaft and the seat hole is poorly centered, or the shaft length is deflected. In the case of a large c... read more

  • The culprit of bearing noise

    In general, the vibration in the bearing, the rolling bearing itself does not produce noise, and the usual "bearing noise" is actually the sound effect of the bearing directly or indirectly vibrating with the surrounding structure. This is why many times noise problems can be considered as vibration problems involving the entire bearing application. When a radial load is applied to a bearing, the number of rolling elements carrying the load changes slightly during operation, which causes a shift in the load direction. The resulting vibration is unavoidable, but can be mitigated by axial preloa... read more
