I'm sure we'll be able to help replace your roller but first we'll need a little more information. Could we see a photo showing the screw and screw hole ? We would also like to know the height of the housing and the width,  both with and without the bumps. Finally, what is the wheel diameter?

Thanks for getting back to us. I'm afraid that I couldn't find an exact match for your roller. Take a look at the 81-139, which comes with either a nylon or metal 1-1/4" diameter wheel. We also have the 81-148, which comes with a 1-1/8" steel wheel. See if either of these match up to your dimensions.
