v belts

[Frank S]

Like Doug said a lot depends on the application, plus the driving pulley diameter sped reduction ratio IE the driven pulley diameter divided by the driving pulley center distances will it be a continuous load drawing full rated wattage or varying loads.
If your loading is intermittent rarely requiring full power and the small pulley is the driving pulley at least 7 times in diameter of the width of the belt then
the short answer would be probably, but in general the short answer would be not quite.
And if the driving pulley diameter is to be less than 7 times the width of the belt or the driven pulley is smaller than the driving then the short answer would be no
