Industrial variable speed belt (V/S belts) and agricultural speed belts are not only resistant via temperature and oil, but they
are also anti-static. These belts are a combination of particular rubber along with a fabric made of fibers that creates stability on the top surface length and minimizes shape transformation and
curvature of belt profile. Cogged shape of these belts maximizes its flexibility and therefore guarantees the best fitness on pulleys. Belt's cord which is the main factor in power transmission
is designed for heavy duty functions and at the same time creates a tremendous stability against length transformation. Sometimes such belts are produced in a special manner i.e. belts with
Kevlar cords or double-sided belts.
