Finding the correct size motor for application

I am working on a project that entails motorizing a roller to be able to feed a rubber filler through. It is known from calculations that our max desired rotational velocity is 200 rpm while we will be working mostly from about 80 to 140 rpm. I was thinking the following motor would be a good choice, but I don’t know if the torque will be enough.

The rubber fillers going through range in size from about .05 to .4 inches. I believe this will not require much torque, but was hoping for some advice from people who know more about motors than I do.

I would appreciate any help.

Thank you

Have you taken a look at the drive motor sizing tool?

You can use the results to get an idea of the motors and battery you’ll need.
