Rolling bearing selection process

Number of applied to rolling bearing selection process is almost countless operating conditions and environment is difference is very big. In addition, a variety of operating conditions and bearing demand continues to grow rapidly technological progress. Therefore, it is necessary to study bearing from many angles to choose the best from thousands of types and sizes are available. Normally, temporary bearing type selected for operating conditions, installation, easy to install in the machine, allowing the space, cost, availability and other factors. Then select the size of the bearing to meet the expectations of life. In doing so, in addition to the fatigue life, it is necessary to consider the service life of the grease, noise and vibration, wear and other factors. Have no fixed method to select the bearing. It is a very good investigation like the experience of the application and research related to any special requirements for your specific application. When choosing a new machine bearings, unusual operating conditions or bad environment bearing selection procedures are considered complete. Self-aligning roller bearing self-aligning properties are also want to consider: when the centerline of shaft and bearing seat centerline, Angle error, or because of the axis of two supporting spacing of larger shaft rigidity with smaller, easily bend or tilt, can choose good self-aligning properties of self-aligning ball or spherical roller bearings, as well as outside of the ball bearing. Such bearing on the shaft bent slightly tilted or circumstances, to maintain a normal work. Bearing self-aligning performance is good or bad, rather than allow no alignment, coaxial degree value is larger, the heart performance better.
