• What are the causes of vibration damage of deep groove ball bearings (2)

    Excitation due to the change in the number of rolling elements: 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 preloading and applied to all rolling elements (not for cylindrical roller bearings). www.nb-huayi.com read more

  • What are the causes of vibration damage in deep groove ball bearings?(3)

    3. Contaminants: If operating in a polluted environment, impurities may enter deep groove ball bearings and be crushed by rolling elements. The degree of vibration generated depends on the amount, size and composition of the particles being crushed, although it does not produce a typical frequency form, but an irritating noise can be heard. www.nb-huayi.com read more

  • What are the causes of vibration damage of deep groove ball bearings (4)

    4. the accuracy of the relevant components: in the case of a tight fit between the bearing ring and the bearing housing or the drive shaft, the bearing ring may be deformed in accordance with the shape of the adjacent components. If deformation occurs, vibration may occur during operation. The causes of noise generated by rolling bearings are more complicated. One is the wear of the inner and outer rings of the bearing. Due to this wear, the bearing and the housing, the bearing and the shaft are broken, resulting in the axis deviating from the correct position and generating an abnormal sound ... read more

  • Basic knowledge of deep groove ball bearings

    Deep groove ball bearings are a more common type of rolling bearings. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. The deep groove ball bearing types are single row and double row. The deep groove ball structure is also divided into two types: sealed and open. The open type refers to the bearing without sealing structure. The sealed deep groove ball is divided into dustproof seal and oil proof. seal. The dust seal cover material is stamped from steel plate, which is simple to prevent dust from entering the bearing raceway... read more

  • The main points and functions of the choice of outer spherical bearings

    The market requirements for various mechanical devices and instruments using rolling bearings are becoming increasingly stringent, and the conditions and performance required for the outer spherical bearings are becoming increasingly diverse. In order to be able to select a suitable outer spherical bearing from a large number of structures and sizes, it is necessary to study from various angles. When selecting a bearing, generally consider the arrangement of the outer spherical bearing as the shafting, the ease of installation and disassembly, the space allowed by the spherical bearing of the ... read more

  • Deep groove ball bearing quality grade standard

    Deep groove ball bearings, different grades of bearings, the price difference is very large. There are three main criteria for evaluating the quality of deep groove ball bearings: 1. Tolerance of bearings: tolerances and shape tolerances of deep groove ball bearings are expressed by tolerance class. For example, P6 is better than P0, P5 is better than P6, and P5 is twice the price of P6. 2, vibration level: there are Z0, Z1, Z2, Z4 and so on. Z1 group is better than Z0 group, Z2 group is better than Z1 group; or V1 group is better than V0 group, V2 group is better than V1 group, etc. 3. Noise,... read more
