Roller bearings deep groove ball bearings in the selection process should pay attention to the working conditions of the bearing, the force and the rated load and limit speed point of view, the following to introduce you to roller bearings deep groove ball bearing choice article.
Whether the correct choice of deep groove ball bearings on the host can get good performance and extend the service life of enterprises to reduce maintenance time, reduce maintenance costs and improve the operation of the machine, has a very important role. Therefore, whether the design and manufacture of units, or maintenance of the use of units in the choice of roller bearings deep groove ball bearings must attach great importance to, in general, the choice of deep groove ball bearings may be summarized as follows:
Selection of roller accessories Deep groove ball bearings of the main considerations are the limit speed, the required life expectancy and load capacity, other factors will help determine the type of deep groove ball bearings, structure, size and tolerance levels and clearance requirements for the final Program.
Various types of deep groove ball bearings with different characteristics, suitable for a variety of different machinery used. When selecting a deep groove ball bearing type, the following factors should be considered. Under normal circumstances: the choice of thrust bearing thrust bearing, angular contact bearings, high-speed applications are usually used for ball bearings, to bear the heavy radial load, the selection of roller deep groove ball bearings. In short, the selection of personnel from different manufacturers, many of the deep groove ball bearing products, the selection of the appropriate type. Selection of several factors to consider:
(1) deep groove ball bearing mechanical space and position of the deep groove ball bearing selection considerations several considerations
In mechanical design, generally determine the size of the shaft, and then, according to the size of the shaft selection of deep groove ball bearings. Usually a small axis selected ball bearings, large selection of roller bearings. However, when the deep groove ball bearings in the direction of the diameter of the machine is limited, the selection of needle roller bearings, special light and ultra-light series of ball or roller deep groove ball bearings; deep groove ball bearings in the machine axial position by Limit, can choose narrow or narrow series of ball or roller deep groove ball bearings. Several Considerations on the Selection of Deep Groove Ball Bearings
(2) deep groove ball bearing the size of the load, direction and nature
Load is selected roller accessories deep groove ball bearing the most important factor. Roller bearings are used to withstand heavier loads. Ball bearings are designed for use in bearings with low or medium load, carburized steel or bainitic hardened bearings. They can withstand shock and vibration loads. In the direction of the role of load, pure radial load to bear, the choice of deep groove ball bearings, cylindrical roller bearings or needle roller deep groove ball bearings. Bear a smaller pure axial load, the choice of thrust ball bearings; bear a larger pure axial load, the choice of thrust roller deep groove ball bearings. When the deep groove ball bearings to bear radial and axial joint load, the general choice of angular contact ball bearings or tapered roller bearings. For cantilever support structure, often using tapered roller bearings or angular contact ball bearings, and used in pairs.
