Four Seasons Sunroom Window Crank

Thanks for posting. Do you mean you're looking for the rollers at the end of the arms of a Sunroom Operator like our 39-465? If so, I'm sorry to say these components are not sold separately and you will need to replace the entire mechanism. I apologize for the inconvenience. If this is not what you need, please send photos of the hardware in question so we can properly identify them, and I'll try and find something better for you.
