I managed to get enough wheels from this set to do what I wanted, but you can grab the center bearings and wiggle the plastic roller back and forth a bit. I don't think the spacers between the pulleys are as wide as the shoulder in the pulley and this mismatch allows for some play. It's excellent value for money, but test the ones you intend to use before screwing them in.
