Has you can see from  the pictures we have our shafts going straight through the roller making it stronger than the original.

we have also changed the design for the outer shell of the roller by welding on grips so that the roller would not collapse in the middle. 




We can see from the pictures of the old rollers this is what happens with them over time.

The rollers to go in the middle since the shaft does not go straight through along with the roller collapsing since the steel is crimped to make the grips.
