I just got a 12mm self aligning pillow block.How do you align these
things,it is off by at least 15 dgrees,I can't align it on a straight
line, on both axis.Thanx

The bearing insert has a convex outer race. It turns in the housing. Stick
a shaft/punch/whatever through
the hole and move the bearing . Some are pretty stiff. If it still won't
move, look for a small pin
on the outside of the outer race that engages a slot in the housing. Some
bearings use this as an
anti-rotation device. Align pin with slot, rotate into alignment with
shaft/punch.

O.K. the 12mm size matches up with the posting through a news
server in Germany. But it *still* feels like a troll.

Just in case it is for real:

Take *two* of the self-aligning pillow blocks, feed the 12mm
shaft through them, and bolt them both down to the mounting surface.
The bearings will live up to their name by self aligning. But you do
need the second bearing to define a unique axis. With just one, it can
wobble all over the place, depending on the forces applied to the shaft.

Enjoy,
DoN.
