Proven in the Field
The Aramid Cord Difference
Compared to polyester cords, aramid offers greater strength, better dimensional stability, and improved shock resistance. That means longer belt life, fewer failures, and more uptime.
- Withstands peak loads and sudden shock forces
- Ideal for systems with frequent start-stop operation
- Reduces the need for frequent tensioning and replacement
Aramid Cord: Trusted in Demanding Applications
BESTORQ aramid cord V-Belts are proven in environments where standard belts fail.
Agriculture
Withstand high shock loads and variable torque during harvest, reducing downtime in peak seasons.
Construction
Maintain belt tension and integrity under heavy vibration and start-stop operation on the jobsite.
Oil & Gas

FAQ
You Have Questions. We Have Answers.
What makes aramid cord different from polyester?
Aramid cord has a much higher tensile strength and resists elongation better than polyester, especially in applications with heavy load and shock.
When should I use an aramid cord V-Belt?
Any time your system sees high torque, sudden stops, starts, or shock loads. They’re ideal for aggressive drives and harsh industrial environments.
Do you offer these aramid cord belts in banded configurations?
Yes. BESTORQ stocks both single and banded aramid cord belts, including wide banded belts for high-horsepower applications.
What makes aramid cord belts different?
Belts reinforced with aramid cords are built for high shock loads and extreme conditions. They offer minimal stretch and are ideal for demanding applications where durability is critical.
How many ribs are available in aramid banded belts?
Standard configurations go up to 20 ribs in 8VK, 29 in 5VK, and 30 in 3VK. Custom options are also available on request.
