Yes, the bearing element combi214 is 2D and used for lateral rotordynamic studies where the stiffnesses are in the plane perpendicular to the axial.

In your case, we can use a spring/damper to represent Thurst bearing. You may use a general joint with the axial DOF set to free and add a stiffness value in the axial direction. Or use a bushing bushing element as convenient.
