Hi,
I believe the replacement part I'm looking for is most likely your
81-250, but I want to confirm before ordering them. The images don't have a plastic roller part around the bearings since this is the part that broke off. When measuring another roller, I think the diameter was closer to 3.25cm which might be closer to the
81-271. If it's not able to be identified, do you have a recommendation which one would work (my guess is the 81-271)?
Thanks.
