R Reemmaarrkkss::
The various designs (and different spring bolt dia-
meters) in Airlight II steel hanger brackets and Air-
light II channel crossmembers mean there are
different types of wear disc. Wear discs with an im-
pression are required for hanger brackets with
angled side walls. Wear discs without an impression
are used for hanger brackets and channel cross-
members with perpendicular side walls!
With impression Without impression
A max. paint coat thickness of 30 µm in the area
of the bolt contact surfaces must not be exceed-
ed!
