roller for aluminum sliding window

A quick learner from Fort Myers, FL says:
This is a long shot, but I thought you might recognize this roller. It's from a sliding window in a condo here in Florida. The label on the window has faded and I cannot tell who made it. Can you tell what it is and do you have a replacement?

We will do all we can to help you. To start, we will need for you to remove the part from the door and send additional photos, with measurements for us to review. Thank you.

Sorry for the delay. I finally got a minute to pull the roller off and take a few photos. They are all plastic and fit into a slot in the aluminum frame. An all metal version would likely do a better job. Thanks.
