Funny you should say that, here's my recent findings about the similar FK12

FK bearings are slightly differant but same applies they can go both ways around. Then only thing with FK is that you can only use one side of the flange but which way it fits on the screw doesn't matter.
When I've fitted them I've always found it best to fit the flange to outside of bracket or plate holding then this way it makes removing screw easier.
If you put it on inside it's trapped and makes removing harder and means taking brackets or plates off to remove which then means you have to realign again when replacing. Where if you machine brackets accurate so nice fit for bearing then removing screw for what ever reason is simple and goes back in same place without disturbing anything.! . . . . If that makes sense.??
