You did something wrong then. these allow you to fine tune to precision with absolutely no binding of any sort which is why they are the rod ends of choice for RC aircraft. If they were binding on you it is because you had the little screw too tight, therefore applying too much pressure on the ball to create the resistance. The proper way to set them up is to place the securing screws on the end and tighten the little screw so it doesn't allow the screw to move/drop and then turn it out until it drops to the bottom and turn out a hair more. that ensures absolutely no binding of any sort.
