Comparing Selected Bearings
This example compares the performance of two cylindrical bearings.
The cylindrical bearings are of the type SKF NU 306 ECP and NSK NU 207 EW. It is possible to switch between these two options by right-clicking the bearing and choosing the desired bearing under Redeclare Component, as shown in Figure 1. Please note that it is necessary to run the simulation for one bearing to store its results, then come back to the Model Center and redeclare it.
Figure 1: Redeclaration of bearing in Model Center.
Now, it is possible to compare any outcome of these two bearings. For instance, the roller forces of the NSK NU 207 EW are smaller, which is an indication of less deflection.
