Constraining Node to follow a defined path

Constraining Node to follow a defined path

Constraining Node to follow a defined path

(OP)
I have a problem where my structure is constrained by a number of bearings that are allowed to roll inside their slots. Under load, the bearings may roll to different positions as the structure deflects; How do I constrain the nodes which represent these bearings to translate along the slot centerline? I have the curves which define these lines. Also, the reaction force at these nodes must be normal to the curve at that point to properly represent the contact there.

Thanks
