(*) Traction force (chain or belt) T x = F x

The rollers with concentric sleeve are mounted where there is the highest load and the ones with eccentric sleeve on the opposite end.

All 'F' values must include the dynamic component obtained by: Inertia force = mass (kg) x acceleration ( mt/s 2 ).

Important : the load on most loaded rollers must be, for each roller type, less or equal to the corresponding rated load on the catalogue.
