M=S „Matched Sets”
These are raw-edge moulded cogged V-Belts which can be used in sets without measuring.
Due to special manufacturing processes the smallest length tolerances are achieved. This is why V-Belts of the same nominal length can be matched at will. A superior smooth running ability is also achieved by precise flank grinding. The same power transmission capability for each V-Belt ensures high efficiency. That saves enery. Set code numbers are not required, there is no need to tie belts in sets. Consequently, stock keeping is reduced and costs are lowered.

Optibelt Kraftbands are especially suitable for critical drives on trucks and buses.
· maintenance free operation
· smooth running
