In de Teileliste und im Reparaturhandbuch sind für die Radlagerung Kegelrollenlager aufgeführt.Beim Zerlegen habe ich aber je ein INA Nadellager und ein doppelreihiges Rillenkugellager angetroffen.
Frage: Wer weiß darüber etwas?
Für jede Antwort bedanke ich mich im Vorraus.

If you need general information about tapered roller bearings, needle bearings and ball bearings, I do not know this.
For our bikes, the swing arm and wheel bearings are tapered roller bearings. The steering bearings are originally ball bearings but should be replaced with tapered roller bearings.
If you just want to know which bearings to order for your R26, here is the information from Huggett's catalog:
07 11 9 985 005 Taper roller bearing 30203 , swing arm R26 - R69S & wheel R26 - R27.
31 42 2 000 000 Taper roller bearing set for steering head, R5 - R71; R24 - R69S.
Sorry for the English - hope this helps.

One more time!
my problem:
In the part list and in therepair manual taper roller bearings are specified for wheel bearings.However, on dismantling i found one double ball bearing and one needle bearing.
How can it be?

Maybe someone put in the wrong bearings, which fitted and worked.
Or, maybe those are original bearings and tapered roller bearings are a modern improvement.

Servus Werner,
The wheel hub that you have is from a R25/3 which has a needle bearing on one side and a double roller bearing on the other side. Optically, the wheel hub is identical to the R26 and R27. There was even a BMW factory bulletin which advised to up grade the R25/3 wheel bearings to the taper roller bearing system.
Best regards,
Mark
