H 45  mm   
  46  Number of fixing holes in inner ring
Attention!
For fixing holes in the adjacent construction.
Note the pitch of the bearing holes.
  45  Number of fixing holes in outer ring
Attention!
For fixing holes in the adjacent construction.
Note the pitch of the bearing holes.
    The measuring head cannot be mounted between the fixing holes or the heads of the fixing screws. Two holes for fixing screws therefore remain unused in the bearing outer ring.
