Synchronous Belt sizes are identified by a standard number. The first digits specify the belt length to one-tenth inch followed by the belt section (pitch) designation. The digits following the belt section designation represent the nominal belt width times 100. For example, an L section belt 30.000 inches in pitch length and 0.75 inches in width would be specified as a 300L075 Synchronous Belt. The nomenclature for double-sided belts will be the same as for single-sided belts with the addition of the prefix “D” in front of the belt section – Example 300DL075.
STANDARD SECTIONS.
Belt sections are specified in terms of “pitch”. Table 8 gives the Standard B
NOMINAL TOOTH DIMENSIONS.
Table 9 and Figure 7 show the nominal tooth dimensions for each of the standard belt sections. The tooth dimensions for double-sided belts are identical to those of a single-sided belt.
PITCH LENGTHS.
Standard belt pitch lengths, belt length designations and numbers of teeth are shown in Table 10.
WIDTHS.
Standard belt widths and width designations are shown in Table 11.
