Please don't think I am insulting you with my direction, the bearings will be damaged if pressure is applied to the outside ring during installation.
You can not apply any force what so ever that will be transmitted to the balls during installation.
See the attached PDF.
Use a sleeve to install the bearing by pushing on the inner ring only, doing so will eliminate bearing damage.
If you are pushing a shaft through the bearing then the inner ring must be supported.
If you decide to use Loctite, apply it with a micro syringe and be extremely careful.
The capillary action will cause it to contaminate the bearing in short order.
