That's probably the best option - I have to do it all the time to ballscrews from Chai. Freezing the ballscrew and/or heating the bearings can get it to slide on to the shaft, but you risk there being too muck friction which may stop you being able to pre-load the angular contact bearings since they require a 'just sliding' fit.
