It's the original bearing.
I am trying to find a place that might have a press to do the job.
I seem to be shadowing you with this job as I've just replaced this bearing as the old one was worn out.
After checking the housing for burrs, I gently drove the bearing into it using a small amount of bearing grease in the housing, a large enough socket to just fit over the outer bearing casing and a rubber hammer. It went in without much drama.
I then carefully fitted the drive shaft through the bearing centre and gently tapped it home - once again, all OK.
I have access to a 20tn press but usually only use it to remove and refit bushes to car suspensions etc.
