UM3 X axis bearing reference

[LeForry 0]

Hi all, I have had a bearing fail on a UM3, giving a grinding noise when I run freely with no belts. Aligned checked, but same problem. 

It is an 8mm ID, 16mm OD flanged, the traditional ultimaker resellers don't seem to stock them. Does anyone have a refence number, or know the specs so I can order one? 
Many thanks,

Hi,

the Ultimaker part number for the ball bearing (F688-2RS) is 1220, according to the official parts manual (see page 7)

The official resellers should have it, even if not listed on their HP, all they need is the part-#.
