Guidelines for Bearing Loads
When working with bearing loads, keep the following guidelines in mind:
• Bearing loads are not available in FEM mode.
• You can apply this type of load to a non-right cylindrical surface with spline.

 A bearing load applied to an elliptical surface in Wildfire 3.0 or earlier is invalid in Pro/Engineer Mechanica Wildfire 4.0 and later versions. |
• The cylindrical surface must have a straight centerline and a constant radius.
• If you select several holes, while applying a bearing load, the load is not divided between the selected holes. Instead, each hole is assigned with the bearing load that you specified on the Bearing Load dialog box.
• You can apply this type of load to open surfaces. However, surfaces must be connected to form a portion of a cylinder. The software displays the bearing load distribution toward the inside of the surface region.
• The vector you specify must have at least one component that is not parallel to the axis of any hole you select. If you specify a vector that is fully parallel to the axis, the software does not accept the load.
• The software defines a bearing load distribution as a cosine distribution that does not vary down the length of the centerline. This distribution enables you to quickly apply compression-only bearing loads to cylinders and rings.
• If the load is not symmetrical about the axis and if the resultant load is not passing through the selected references, the load may create a moment about bearing axis. Use the
