DONGIL V BELTS are "everset", no matching codes required
 
CORRECT TENSIONING OF V-BELT DRIVES
   1. Measure the span length.
   2. At the centre of the span apply force at the right angles to the belt to
       deflect one belt 1mm per 100mm span length.
   3. Compare this force with the values given below. If it falls within these
       values, the drive tension should be satisfactory.
BELT DESIGNATION
S.A.B.S. belt designation denotes pitch length in millimeters i.e. 10N (SPZ), 13N (SPA), 22N (SPC) and 25N (DELTA).

Belt designations shown in heavier type identify preferred sizes in S.A.B.S. lengths.

Although the cross sections are identical, some manufacturers use other belt designations:
  10N (SPZ) Interchangeable w Alpha
16N (SPB) Interchangeable w Beta
25N (Delta) Interchangeable w Delta
