anyone know what this tool is for?

Slightly confused about the purpose of this tool, said to be for the 348 355 voith system. But cant see where threaded portion or indeed any part of it would go to be of any use in there.

And apologies now if a repost!

 

I thought too small at first, but we dont know how big that tool is.
I now see what you mean ernie assming its big enough to cover the whole bearing and push it down on outside, the other end looks like it will screw down and pull the bearing in using the voith.
Next question is why on earth bother when its easier to use a press to push bearing it and turn it over to push voith unit into it? especially at 250 quid!
