Hi,

i am pretty shure those parts are standard bearings type F10-18M. Should be available on E-Bay...or even the last gas station before the highway...

Yours sincerely

Rainer

Yes,

In 2021/2022 we talking about this here.

I still have a few of them here

How could they are being silent whit that amount of balls?

Let's rumple !

Soweit ich mich an die früheren Diskussionen erinnere, sind reine Stahllager materialbedingt nicht die leisesten Konstruktionen. Allein deswegen setzten Dual und z.B. Elac Materialkombinationen ein.

Heutige 2K-Lager arbeiten mit hochmoderen Beschichtungen, um leise zu laufen. Diese Lager sind aber ganz anderen Belastungen ausgesetzt. Die vergleichsweise wenig belasteten und simplen Plattentellerlager sind mit den Stahl-/Kunststoffkontruktionen schon damals in die Zielrichtung der preisgünstigen Laufruhe konstruiert worden. Das Lager meines Miracord bestand bis auf die Kugeln (und das außenliegende Gehäuse) nur aus Kunststoff: Laufflächen - ohne Käfig. Das empfand ich als laufruhiger als die Duallager.

As far as I remember from earlier discussions, pure steel bearings are not the quietest designs due to the material used. For this reason alone, Dual and Elac, for example, use combinations of materials.

Today's 2K bearings work with state-of-the-art coatings in order to run quietly. However, these bearings are exposed to completely different loads. The comparatively lightly loaded and simple turntable bearings with their steel/plastic constructions were already designed back then with the aim of running quietly at low cost. Apart from the balls (and the external housing), the bearing of my Miracord consisted only of plastic: running surfaces - without a cage. I found this to be smoother running than the dual bearings.

Just try.

So the conclusion is? 🙃

Look for an used original platter bearing.

If you want to try ceramic balls. I use them in my Dual 1228 and will also put them into the 1229. The Lenco L78 with one ceramic ball is dead quiet. Ok, totally different construction, but the platter bearing of the 1228 also makes no noise. Here the idler wheel and the motor itself are audible.

By the way I use Marine bearing grease in the bearings.

Try some Grease.

Bicycle pink grease maybe?

Try it baby, try it
