Wash the open ball bearings in acetone, glue it in the role, and then grease with a drop of WD40 or sewing machine oil.

The wheel must be balanced: the wheel must be installed and the heaviest part of the wheel will be turn downwards. On the rear side of the wheel is a groove for the counterweight. They should be glued in after testing. I used copper wire. The aim is that the wheel should remain in any position, making a very precise measurement possible.

1 pcs. Ball bearing FAG 624 (13mm, 4mm, 5mm thick (Conrad Electronic, Item No. 186209-62)
1 pcs. M4x20 screw and washers

Die offenen Kugellager in Aceton auswaschen, in die Rolle einkleben und dann mit einem Tropfen WD40 oder Nähmaschinen- Öl schmieren.
Danach muss das Rad gewuchtet werden: das Rad montieren und warten, die schwerste Stelle wird nach unten drehen. Auf der hinteren Seite des Rades befindet sich eine Rille, in die man die Gegengewichte einkleben kann. Ich habe Kupferdraht verwendet. Das Ziel ist, dass das Rad in jeder Position stehenbleibt und so eine sehr präzise Messung möglich macht.
