l Superior Flexibility & Small Pulley Adaptability:

The inner cogged design reduces the bending resistance of the belt, allowing it to fit small-diameter pulleys (minimum pulley diameter is 30% smaller than traditional V-belts) without excessive stress, avoiding cord damage and extending service life.

l High Transmission Efficiency:

The cogged structure reduces contact friction between the belt and the pulley groove, improves heat dissipation performance, reduces energy loss, and the transmission efficiency can reach 96%-98%, which is 2%-3% higher than that of traditional flat-bottom V-belts.

l Strong Load-Bearing Capacity:

Reinforced with high-strength cords, combined with the reasonable stress distribution of the cogged design, it can bear high torque and load, resist stretching and breaking, and is suitable for high-speed and heavy-duty transmission scenarios.

l Heat Dissipation & Wear Resistance:

The notches on the inner surface increase the heat dissipation area, effectively reducing the temperature rise during operation; the wear-resistant fabric covering and high-quality rubber material enhance the wear resistance and oil resistance, adapting to harsh working environments.

l Wide Compatibility & Easy Replacement:

It has the same external dimensions as traditional flat-bottom V-belts, can directly replace the traditional V-belts without modifying the pulley, and is compatible with most existing transmission systems, with simple installation and replacement.

Maintenance Tips：

l Replacement Cycle: Replace every 40,000-70,000 km (for automotive applications) or 1800-2800 operating hours (for industrial equipment); shorten the cycle by 30% under high temperature, high load, frequent start-stop or oil-contaminated working conditions.

l Tension Standard: The initial tension should be controlled at 18-26N/mm of belt width; for belts with center distance ≤ 700mm, the deflection should be 1.2%-1.8% of the center distance; excessive tension will accelerate bearing wear, while insufficient tension will cause slipping and overheating.

l Environmental Requirements: Avoid long-term contact with engine oil, gasoline, coolant, acid, alkali and other corrosive substances to prevent rubber aging and cord corrosion; the recommended working temperature is -30℃~115℃, and avoid continuous operation at temperatures exceeding 125℃.

l Regular Inspection: Check the belt surface, cogs and cords every 700 operating hours; replace immediately if there are cog wear (exceeding 12%), cracks, cord exposure, rubber hardening or delamination.

l Installation & Usage: Do not use sharp tools to pry or scratch the cogs during installation to avoid damaging the belt body; ensure the pulley groove is clean, free of debris and wear, and the belt is correctly installed in the pulley groove without deviation.
