It seems your new bearing is not and even in place It is not the right one.....
But that is not the reason why it does not fit, I think the bearing has wrong tolerances. I am busy with a drill/mill unit and has ordered 10x bearing 8x16x5, one of the bearings does not fit on the 8mm shaft, cheap chineese crap.....
I would conntact the seller and make a complain, please to not grind down the shaft to make it fit, another right bearing will give play....
Just get an original steel one, do not think ceramic will make a difference.
Hi Roelof,..the bearing does have the offset of 0.3 mm as I specifically asked for it. The website doesn't tell it but I knew I needed the wider innerrace for exactly the reason you're saying. In between I measured the innerrace diameter again. A couple of times actually and from various positions. It turns out the diameter measurements are between 14.11 and 14.18 which is more then a tiny bit off the spec of 14.20. In other words a tolerance which is way too much.
Im already in contact with Dialled RC and no problem to either send it back or send anotherone.
