FLIGHTS AND
SIDEWALLS

Siegling – total belting solutions

FLIGHTSProfiles (PU-flights)– Belt widths greater than 1,300 mm (51.18 in) can also be fitted with lateralprofiles, provided that gaps are acceptable for the application.
– Flight notches available.
– Contact customer service for additional fabrication tolerances,recommendations based on design, and application.

the lateral profile and the sidewall must be taken into account.
The highest value is vital and must be adhered to. The dmin figures
are guidelines. They were determined at normal ambient conditions(20°C/50 % humidity.) Lower temperatures require smaller diameters.
