Stupid question about constraints on cylindrical faces

Hy everyone,


I was simulating bearings' radial stiffness with SW when I found out this problem.

With reference to the highlighted face below, is it possible to constraint the face radially only in case of radial displacements directed through the Brg axis and, at the same time, free the radial displacements directed to the outer bearing cage?

In a non-cylindrical face I would normally use a virtual wall but this is not the case.

Any strategy to solve this trivial issue?


Thank you in advance

Brg model


edit: What if I use a rigid bearing support fixture at the cylindrical face? Does bearing support fixture work in just one direction?
