The plastic is acetal (Delrin) so it's pretty slippery. In this application the belt's not moving that fast or that often so I think the tensioner will hold up OK. I took it apart after a day of practice and did not see any noticeable wear on the tensioner or belt.
By the way, we have slots in our shaft mounts, but we were not able to get enough tension in both sides of this long belt that way.
