Question about Mike New bearing?

[Desmo]

I have just oiled my VPI bearing with some Origin live oil - very good stuff indeed.

A review of bearing oils was done and this one came out top - spin test (amount of revolutions after spinning up and leaving to stop)

+1 for the Origin Live oil - I use it in my Systemdek, and it is excellent.

How come the oil never needs changing?

Hi Andrew,
I have just picked up this thread (Sunday Afternoon) and I believe I have answered your question on the "Mike New Bearing" Thread or else where.
The general answer is that the bottom vertical support bearing-well is sealed.
The lateral support bearing is a honed and oil impregnated syntered hard Phos-Bronze insert. And as such does not really need any oiling.
I supply a small syringe of oil to seal the top of the bearing from dust more than for lubrication.

Yep, I saw that when you posted.

Superb explanation!

if it's an original Systemdek with the spiral cut into the spindle, the design used EP80 or even EP90 in the earliest ones, doe to viscosity and thickness.

My one is a later model with the plain spindle, resting on a ball bearing. The Origin Live oil is just fine. But I do have plenty of EP80/90 in the garage should I ever need it. More likely to use it in axles and steering boxes though!
