That's an interesting point.
I guess it is possible that the idea is that the gearbox oil washes
the bearings
Gentlemen,
My goal would be:
A spring loaded lip seal at the bottom of the gearbox - above the spindle
bearings. Size the seal or bearing surface for approximately 1/2 the
recommended interference fit to minimize heat in the seal. If you are
turning the head over then a seal at the top would b
The Hardinge CHNC turret uses those quad rings to seal the turret and
the housing.

I haven't really started "restoring" it yet. It is as I bought it
apart from making a few small parts that were missing.
I wanted to get it working properly to make a decision on the stat

Ah, OK. That was pretty much the plan already, then.

I have tried re-greasing to see if it helps.
The problem is that it is more than the odd splash, it will be nothing
at all for age

I've used a special bearing grease designed for spindle.s I have no seals on
mine, just a few dust rings at the bottom to keep the dust out. I put new
bearings in about 8 years ago and the machine works daily. Never touched it
since then.

The spindle of my milling machine has a plate that specifies Vitrea
oil 72 for the gears but Alvania Grease 3 for the bearings.
I suspect that the top bearing needs grease because there is no
prospect of it getting enough oil by splash.
I further suspect that the bottom bearing needs grease becau
