Thanks everyone. I've looked around again and cannot see a 10mm shaft double ended motor. I rang Zapp and they have confirmed its a none standard motor especially with the shaft size but similar to a nema34.
I planned using a couple of pillar bearing and come out with a 10mm shaft to replace the motor and then just drive the shaft with a standard motor.
Before I do that I just wonderd if someone had bought a arceuro motor which was looking for a new home—you never know unless you ask!
