Review on Donepart MR105ZZ Bearings Miniature Skateboard by Adam Quintana

MR105ZZ (5 x 10 x 4mm) -- All outside diameters measure nearly 10.00mm at the tip. All holes are 4.94-4.96mm. I have a 5mm bar that is 4.98mm long and neither is good for slippage. The tolerance for a bearing of this size should be approximately +0.00/-0.01mm per bore. Not this one. Bearing width is 3.98-4.00mm.
