Replacing an operator's bearing wheel

A quick learner from Ludlow, Massachusetts says:
October 16, 2020
Can I replace the bearing wheel instead of the entire single arm operator assembly?
If so, questions:

Is the pin threaded?
What exactly would the replacement part be called?
Do you stock these parts?

Hello,

I don't recognize the wheel on your operator's arm since it is larger than our standard operators but I'm going to have one of our senior experts take a look and see if they could recommend a replacement for you. We'll reach out as soon as more information is available. Thank you!

I would suggest replacing the complete operator and track. I'm not sure of the arm length your operator has but take a look at the operators and track we've related for you to see what parts line up best. Also, make sure to check your hinge to make sure it is also in good working order since you will be working on the window.
