MEASUREMENT
(mm)
Top width x height
(refer to table) |
WIDTH
(mm) |
PITCH BETWEEN TEETH (mm)
To be taken over 10 teeth for more accuracy. |
PITCH BETWEEN RIB (mm)
Take the maximum width
of the ribs and divide by the number of ribs. |
ANGLE EVALUATION
A variable-speed belt may be concerned. |
| INSIDE LENGTH (mm) |
NUMBER OF TEETH
To be multiplied by
the pitch to obtain the pitch length |
EFFECTIVE LENGTH (mm)
Is measured at the rib bottom;
close to the pitch length or outside length. |

LENGTH
Length conversion as per catalogue.
For measurement of a
datum length: unroll the belt flat on its back. |

MEASURED LENGTH : if the belt is worn, take elongation during service (except for synchronous belts) into account. Take the next lowest length in the catalogue. For V-belts Ld = datum length replaces the former Lp = pitch length as per ISO 1081 | | V-belt cross sections
