Talking about the one circled below. Mine is a Koyo DG4380 (80 mm OD, 43 mm ID, 17 mm width), although it has DG4180 marked on the outer race. Guessing they just reused the outer races from an existing 41 mm shaft bearing for a 43 mm shaft.
Anyway, mine has a bit more play than what seems typical. It's 0.002" radial and axial is ~0.020" when moving the outer race linearly, and ~0.025" when allowing it to tilt as well. 0.025" tilt would equate to around 0.018° I think.
I can't find any information about what is acceptable. If anyone has one on hand they could measure, that would be helpful, but at least this could be a data point for anyone else looking for info.
