Its innovative design incorporates a patented "flat spring" mechanism that minimizes tension variation, reducing the risk of premature accessory bearing failure due to excessive tension during new belt installation. There’s also a PTFE string wound within the spring, providing abrasion resistance and dampening noise for a smoother and quieter operation.
