In the picture it looks like the PVC was uncovered. That provided enough "grab" to move the balls with any covering?

Center to center. We added tape over the the pvc to provide a rougher surface. The speed we ran the roller tended to slip on the surface of the ball. On the ends of the main roller we added thread to help grab the ball.
