I just finished rebuilding one of my Lyndex Live Tool Holders and am ready to do a break-in. Does anyone know the recommended RPM and time for this procedure?

Full RPM, chuck full rpm, full rapid. Less than a second and it will be broken.

Without knowing the specifics of your tool I'd say it doesn't need to be elaborate.
Start at a couple of hundred RPM and ramp it up slowly over a quarter of an hour or so making sure it doesn't get too warm. If it gets too warm too quickly, stop, let it cool down and start again.
If you really want to do it properly SKF have a very good guide here.

We rebuild a fair amount of holders in our travels and do not put a big emphasis on break in.
We have a specific procedure for our Machine tool spindles which takes about 2 hours but for the live holders:
A: they run a pretty low RPM considering the bearing size.
B: they do not run continuous
C: they are usually cooled by the flood coolant.
That being said, after completion, they are indicated for runout, play etc.
We run them on the Bridgeport at 1000 - 1500 or so for 10 15 min just to monitor for noise and heat.
After that they are on their way. It has worked for us so far.

the biggest thing thats helpful in an oil mist spindle install break in is you are purging the air mist ssytem so you don't run full rpm fuill load without oil in the system for the new bearings. Live tools I have seen are permanently lubricated so monitor housing temp after you fire them up a few minutes, if they get hot you might want to reduce some preload.
