When ordering, please state the overall height of the V-belt including top surface. This is indicated by the section designation as follows.
Section B/17 – top surface within the standard height = 17 x 11 Section B/17 – with additional 3 mm top surface = 17 x 14 Section B/17 – with additional 5 mm top surface = 17 x 16
