Can you tell me the diameter of 87-089 at the smallest point of the groove? Thanks. I'm looking for a ball bearing roller with less than 0.43" at smallest diameter.
This doesn't have ball bearings, but it might be good enough. Do you know of a better choice? Slide-co has 172531 with an outside diameter of 5/8", but I don't know the groove diameter. Do you have a roller like that?

It appears that the inside diameter of the 87-089 is close to 1/2", which is .50". you say you need an inside diameter of .43", though. If you want, send us a photo of the original roller you need to replace along with dimensions. Maybe we can better identify the part you need.

This is not for a replacement. It is not for a door or window. I'm building a tool. It would be hard to explain. I just need 3 concave rollers less than 0.43" at the center. Ball bearings would be nice. An axle like this one would be second choice. I may have to try 1/2". It might work, but smaller would be good.

Ah, I see. I'm afraid the 87-089 is the closest we have. I don't think we have anything quite like you describe.
