Re: PVC Rollers?

We used 1/16 thick clear polycarb rollers this year on our front convayor. It worked very well, no problems. Polycarb is very durable and springs back unlike thinwall aluminum tubing. We used thinwall aluminum for rollers inside the robot to reduce weight.

Instead of larger diameter rings I would suggest a belt comb. This year, we began with no belt combs and ended with a belt comb on all of our polyurthane belt runs. It's not that PVC rings don't work but a comb ensures that the belt can't walk down the roller. Even if you pull the belt off of its "spot" on the roller it'll walk back. If we use polyurthane belts in the future, which I'm sure we will, you can be sure that we will also use a belt comb.

Regards, Bryan
