All kinds of SKF bearings with different characteristics, different using conditions applicable to all kinds of machinery. Selection of bearing type, usually should consider the following factors. General: the thrust load selection of thrust bearing, angular contact bearings, usually use ball bearings for high-speed applications, bear radial load heavy, choose roller bearing. In a word, bearing product selection of personnel from different manufacturers, many, choose the appropriate type. The process of selecting the bearing should be considered in the following points:

( 1 ) bearing for machinery space and position

In mechanical design, first determine the general shaft size, then, according to the size of shaft bearing. Usually a small shaft using ball bearings, shaft selection of roller bearing. However, when the SKF bearing is restricted in the diameter direction machine, then use the needle roller bearing, light and ultralight series of ball or roller bearings; when the bearing is restricted in the axial position machine, can choose the ball or roller bearing narrow or extra narrow series.

( 2 ) the size, direction and nature of the load bearing

Load is the main factor of the SKF bearing. Roller bearings used to carry heavier loads, ball bearings to withstand mild or moderate load, bearing steel manufacturing or bainite quenching, can withstand the shock and vibration loads.

In the direction of load effects, pure radial load bearing, can choose the deep groove ball bearings, cylindrical roller bearings or needle roller bearings. Pure axial load is small, can choose thrust ball bearings; subject to pure axial load greatly, can choose the thrust roller bearing. When SKF bearings under radial and axial joint load, general selection of angular contact ball bearing or tapered roller bearing.

( 3 ) self-aligning bearing performance

When the shaft and the bearing seat center line center line is different, the angle error, or because of the rigidity of shaft two support spacing is larger and shaft with small, easy bending or tilt, can be selected with good aligning performance self-aligning ball or roller bearings, ball bearings and. This kind of bearings in the shaft slightly inclined or curved circumstances, can maintain normal work.

Work required depends on whether have the similar SKF bearing selection experience. In case of lack of experience, there are special requirements, or the need for bearing configuration cost and any other subsequent appearance to give special consideration, more work needs to be done, such as more accurate calculation and / or test.
