How Do I Mount a Keyed Bore Roller Pinion to a DC Motor?

[sixsouls]

I'm trying to make a 3D model of a linear actuator. I'm using this roller pinion: http://www.nexengroup.com/nxn/products/details/id/966828

It has a keyed bore and says I need a shaft mount but I have no idea how I'm supposed to mount it to a DC motor...

Could someone please explain the parts I will need and how to mount it? I know this is a really stupid question but I've been stuck on this for a while now and it's doing my head in

Motor has parallel shaft also with a key way . Drive is taken by a piece of metal called a key which engages both keyways .

So I have to find a motor with the same sized keyway groove in the shaft, then buy a key and shove it in between the two parts basically?

Basically - yes . But there must also be a means of stopping wheel from sliding off axially when in use . Typically a side screw in wheel or a nut on end of shaft .
