Evidence suggests the increased initial cost is offset by reduced energy consumption and extended operational lifespan, leading to significant long-term savings. However, for applications where abrasion resistance and overall robustness are critical, wrapped v-belts from reputable manufacturers remain a viable, cost-effective alternative.
