• 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

  • Is the oil in deep groove ball bearings normal?

    In fact, the deep groove ball bearing grease is normal, because deep groove ball bearings need grease lubrication to prevent rust and lubrication when running, especially sealed deep groove ball bearings, can not run at high speed without grease bearings The life expectancy is greatly shortened. The survival of deep groove ball bearings is from one process. After assembling the inner and outer rings of the bearing and assembling the steel balls and cages, first flush them, rinse them and then press the sealing cover on one side, then press the bearings. Turn over and add lubricant (usually 30%... read more

  • How to keep the outer spherical bearings clean and stable? (1)

    Fever is a common problem when the bearing is working, and there are many external spherical bearings with high temperatures due to external factors. The temperature rise of the outer spherical bearing caused by different factors needs to be overcome in different ways. In order to completely eliminate the risk of the outer spherical bearing temperature, it is inevitable compared to the solution. Due to the intrusion of dust in the outer spherical bearing during application, the wear amount is large, noise and vibration are serious, which seriously affects the running precision of the bearing, ... read more

    It should also be noted that the attention on the address requires communication between the consumer and the manufacturer to ensure that the package of the outer spherical bearing arrives in the hands of the consumer smoothly, without loss and ensuring efficiency. After the attention, the attention in the mode of transportation is generally related to the quantity purchased by the consumer. When the quantity exceeds the weight that can be transported by the express delivery, the manufacturer needs to pay attention to the supply after the sale. The above is the introduction of the problems tha... read more

  • Principles for selection of non-standard bearing grease

    When using non-standard bearing grease, it is mainly based on the working environment, working temperature and load of the bearing. Working environment Mainly refers to the working environment * low and * high temperature, air humidity, whether it contains corrosive gases or excessive dust. For example, when used outdoors in severe cold areas, lithium-based low-temperature grease should be used; in the case of high humidity and high moisture. Calcium-based grease should be used; in the case of dry and low moisture, it is suitable to use sodium-based grease which is easily soluble in water. 2. ... read more
