Certainly. The diameter of the bearing is 5/8". I hope this helps.
I'm afraid we couldn't locate an operator with a 1/2" bearing like the one you are looking for. However, the 39-520 surface mounted track may be an option if you could install this one on the window. Also, take look at the 39-504 track to see if this could work. Review the specifications along with the related videos and see what you think.
If you don't think they can work for this application, you could try seeing if you can contact a machine shop to switch the bearings around to the bottom side of the operator's arms.
You can place an order for our parts right on our website at your convenience!
