In place of RBE3 constraint, in CalculiX, you could use distributing coupling constraints - not yet supported in PrePoMax but can be added via the keyword editor: [RBE3 integration in PrepoMax (Kinematic & Distributing Coupling)](https://prepomax.discourse.group/t/rbe3-integration-in-prepomax-kinematic-distributing-coupling/44)

Two-node springs may also be added this way: [Spring between two nodes](https://prepomax.discourse.group/t/spring-between-two-nodes/116)

CalculiX offers also kinematic coupling constraints (closest equivalent to RBE2) and rigid body constraints (those are available in PrePoMax but they make the surfaces completely rigid).

I have a few papers about simplified modeling of bearings in Abaqus but they discuss roller bearings.
