Defines, for narrow V-belts of cross-sections 9N/J (for pulley grooves of effective width 8,9 mm), 15N/J (for pulley grooves of effective width 15,2 mm) and 25N/J (for pulley grooves of effective width 25,4 mm), the standard effective lengths, the tolerances on effective lengths, the centre distance variations, the conditions for measuring the effective length and the centre distance variation, and the designation and marking.

This International Standard specifies, for narrow V-belts of cross-sections 9N/J (for pulley grooves of effective width 8,9mm), 15N/J (for pulley grooves of effective width 15,2mm) and 25N/J (for pulley grooves of effective width 25,4mm),

  • the standard effective lengths,

  • the tolerances on effective lengths,

  • the centre distance variations,

  • the conditions for measuring the effective length and the centre distance variation, and

  • the designation and marking.

NOTE1 The cross-section of a narrow V-belt is defined by a number (9, 15 or 25) followed by the letter N or J to denote single or joined belts.

NOTE2 To define belts of raw-edge cogged construction, the letter “X?? is added, i.e. NX or JX.
