If the load is small and smooth, optional ball bearings, when the load is large and impact, it is advisable to select roller bearings, such as bearings only by radial load, select radially contact ball bearings or cylindrical roller bearings, only axial loads, should choose thrust bearings, bearings are subject to both radial and axial loads, angle contact. The larger the axial load, the larger the contact angle bearing should be selected, and if necessary, the combination of radial bearings and thrust bearings can also be selected. It should be noted that thrust bearings cannot withstand radial loads and cylindrical roller bearings cannot withstand axial loads.<br><br>Speed of bearings<br>If the size and accuracy of the bearing is the same, then the limit speed of the ball bearing is higher than the roller bearing, so when the speed is higher and the rotation accuracy requirement is high, the ball bearing should be selected.<br><br>The push bearing has a low limit speed. When the operating speed is high and the axial load is small, angle contact ball bearings or deep groove ball bearings can be used. For high-speed swing bearings, in order to reduce the centrifugal force applied to the roller raceway, it is advisable to choose bearings with smaller diameters and rolling body diameters. Bearings should generally be ensured to operate at below-limit speeds. If the operating speed exceeds the maximum speed of the bearing, the requirements can be met by increasing the tolerance level of the bearing and appropriately increasing its radial play.<br><br>Tuning performance<br>The offset angle between the inner and outer ring shafts of the bearing should be controlled within the limit value, otherwise it will increase the additional load of the bearing and reduce its life. For shaft systems with poor stiffness or installation accuracy, the bias angle between the inner and outer ring shafts of the bearingist is larger, and it is advisable to choose the centring bearing. Such as the tuning ball bearing (class 1), the heart-adjusting roller bearing (class 2) and so on.<br><br>Allowed space<br>When the axial dimensions are limited, it is advisable to use narrow or especially narrow bearings. When radial dimensions are limited, bearings with smaller rolling bodies are advisable. If a radial size is required and the radial load is large, an optional roller bearing is available.<br><br>Fit performance<br>The inner and outer rings of conical roller bearings (3 types) and cylindrical roller bearings (N-types) can be separated and easy to assemble.<br><br>Economics<br>Low-cost bearings should be used when the requirements of use are met. In general, the price of ball bearings is lower than that of roller bearings. The higher the accuracy level of the bearing, the higher the price.<br><br>Other requirements<br>Deep trench ball bearings are the lowest price in the same size and precision bearings.<br><br>The price ratio of deep trench ball bearings of the same model, size and different tolerance levels is approximately PO: P6: P5: P4: P2 1: 1:5: 7: 10.<br><br>If there are no special requirements, should try to choose ordinary level precision bearings, only when the rotation accuracy has higher requirements, only choose higher precision bearings.<br><br>In addition, there may be a variety of other requirements, such as the overall design of the bearing device requirements. Therefore, the design should be a comprehensive analysis of the comparison, to select the most suitable bearing.<br><br>Rolling bearing is also a more sophisticated mechanical original, its rolling bearing type is also very many, the application of a wide range, but we can according to specific conditions, the most suitable rolling bearing, so as to better improve the performance of machinery and equipment manufacturing.
