Gates manufactures all industrial V-belts within industry standard
belt length and belt matching tolerances. All industrial V-belts included in the V80 no-match system are marked with a distinctive "V80" symbol.
The manufactured lengths of industrial V-belts with a
V80 marking are within industry matching tolerances with all Gates belts in the same
size. This eliminates the need for
special belt matching practices for multiple belts used in sets.
Small belt tension variations visible in new belt sets is
normal. Tensioning new belts to
recommended levels and running them in for 24 to 48 hours generally equalizes
all belt lengths and belt tension levels.
After the initial run-in period they should be re-tensioned to the level
recommended for "used" belts.
Occasionally there are special applications with unusually
sensitive performance requirements, or users may be unusually sensitive to belt
tension variations in new belt sets. In
these cases, “precision matched” belt sets may be requested. Precision matched belt sets require hand
measuring, sorting and handling to identify belt lengths within 0.15”, so are
priced at a premium level and may require some lead time.
Precision matched belt sets require a run-in period of 24 to
48 hours and re-tensioning, just like conventional V80 matched belt sets. Other than some potential reduction in belt
vibration during the short run-in period, precision matched belt sets are
expected to perform nearly identically to conventional V80 matched belt sets.
