Aligning counter bearings centrally
1. Undo the two nuts (4) and (5).
2. Move the threaded rod (6) with the counter
bearings (2) and (3) in the required direction
until the two counter bearings (2) and (3)
are aligned centrally again with the base
frame (1).
3. Tighten the two nuts (4) and (5) until the
threaded rod (6) can be turned easily and
without play (do not clamp).
Both the counter bearings (2) and (3) must be aligned centrally to the
base frame (1) if any of the inboard yokes supported by the counter
bearing is no longer centrally aligned with a clamped profile tube.
