Bending direction 2 = concave
Bending can give rise to surface changes (anodising,
torsion) as a result of the deformation. Rail profiles with clear
anodised (CA) surfaces that are undersized by up to 0.15 R = xxx
below nominal diameters are used to improve the surface
finish of the curved rails. We recommend a bend radius of
no less than 300mm and would like to point out that the Bending direction 3 = curved bending
surface finish quality after the bending process depends
on the material quality. It may vary from batch to batch.

With the concave/convex rails, the length (L) of the carriage
is decisive for the desired radius. If the radius decreases
and the sliding distance (L) increases, the gap (S) shrinks.
