Tensile Strength & Load‑Bearing Capacity
Traction Formula
Traction‑grade formulas are engineered to maximize pulling and transmission performance. Manufacturers optimize tension member materials and structural design, often using high‑strength steel cord as the core reinforcement. Special bonding processes ensure uniform distribution within the rubber matrix and strong adhesion between the cord and rubber.
As a result, traction‑formula timing belts can withstand higher tensile loads, resist stretching and deformation under high power transmission, and are less prone to breakage. They deliver stable, efficient power transfer in heavy‑duty industrial machinery and large equipment, supporting continuous and reliable operation.
Other Formulas
Standard rubber timing belt formulas are not specially optimized for extreme tensile strength. They often use conventional fiberglass cords with lower overall tensile performance. Under heavy tension, these belts tend to elongate, reducing positioning and transmission accuracy. Prolonged high‑load operation can damage the tension member and lead to premature belt failure.
While suitable for light‑duty small machinery with low load requirements, standard‑formula belts lack performance in heavy‑load applications.
Wear Resistance & Service Life
Traction Formula
Traction‑grade belts use highly wear‑resistant rubber materials such as specially formulated neoprene or hydrogenated nitrile rubber (HNBR), reinforced with wear‑resistant fillers like carbon black to improve surface hardness and abrasion resistance. Tooth profile and structure are also optimized to reduce friction between belt teeth and
pulleys.
In high‑cycle environments with frequent starts, stops, and high‑speed operation — such as automated production lines — these belts maintain excellent wear resistance, extend service life, and reduce replacement frequency.
Other Formulas
Many conventional formulas prioritize cost control, using general‑purpose rubber materials and basic additives with minimal friction‑reduction design. Under similarly harsh wear conditions, belt teeth quickly suffer from wear, chipping, and delamination, causing premature failure, unplanned downtime, and higher maintenance costs.
Aging Resistance & Environmental Stability
Traction Formula
To support stable performance under demanding long‑term conditions, traction formulas incorporate advanced anti‑aging additives including antioxidants and antiozonants. These enhance resistance to environmental stresses such as UV exposure, high temperatures, and high humidity.
The rubber matrix and tension member age slowly, preserving mechanical properties over extended periods. Even in outdoor applications like agricultural irrigation systems, traction‑formula belts maintain consistent transmission performance under sun, rain, and temperature fluctuations.
Other Formulas
Standard formulas often have limited anti‑aging components. Over time, the rubber layer is prone to cracking, hardening, and embrittlement, while the tension member may degrade due to oxidation. This drastically shortens service life, especially in harsh outdoor or industrial environments.
