Inside diameter is supposed to be 3/16" which in decimal terms is .1875. The shaft I was mounting them on is .187 but yet the bearings wouldn't slide on. I'm guessing the quality is not as good as it should be.

I bought the berings primary for the trim routing bit. I run my router at 25.000 rpm and do not have any issue so far. . I wasn't sure about quality since there is nothing on descryption what is the rpm range. They are cheap.
