Attached is a sample assembly. I converted the document setting to mm to make the issue easier to see. For some reason in this assembly "Insert1" is spacing the faces by .001 mm. We use the bearing on many many parts. This is the first time I have seen this. These parts are from a larger assembly, and oddly only the plate seems to have an issue. The same bearing is used elsewhere without any problems.
I did not draw the plate, but I couldn't find anything that would cause the offset. I'm not sure if this is an odd bug or maybe I missed something?
The problem is with the THKHSR2***S
part. If you measure the distance between the center of the countersink
(green dot) and the face, you will see that there is a .001 mm offset. You
can see it if you zoom in really, really, really close.

Very strange. I never had any issues with the THKHSR model prevously. I wonder why only this plate seems to pick the offset circle for the instert mate.
However, inaccurate downloaded models can lead to problems eventually. I guess this is one of them.
PS This HSR25 model has been phased out for new equipment and replaced by an IV native iPart. In this case it was a near copy of an old machine.
I got it to work fine with this plate if I didn't pick from the top surface of the THK bearing. I needed to pic from the side, ie the hole was hidden.
This bearing has been used on many models, with the multiple bearings on multiple plates all attached to the same rail. This was a similar case, and this plate did not line up with the others. At least for any of my assemblies, if the height was important so things needed to line up or I needed to use a 36mm offset in an equation it worked fine 🙂
