Check for shims under the flanges of the bearings on the metal arms. You may need to remove 1 or both of these so that the bearings touch in the middle. If the inner races of the bearings aren't touching then the bearings will bind when the screw is tightened. some arm designs will have a collar between the bearings, and some are just designed to touch each other in the middle.

It's normal for there to be a little bit of drag in the plastic arm but the metal arm should be completely free when the screw is tightened.
