X5 EPDM Cogged V-Belts
Cogged V-Belts Engineered with EPDM for Superior Performance
BESTORQ X5 EPDM cogged V-Belts redefine industrial power transmission. Built in the USA, they deliver unmatched durability, energy efficiency, and reliability for demanding applications across industries.
With advanced EPDM compounds and precision cogged design, X5 belts resist heat, oil, and chemical wear, outlasting standard belts by a wide margin. Proven in the field, trusted by professionals.
Cogged V-Belt Consistency—No Matching Required
Every belt is manufactured with a one code matching system that allows consistent performance while eliminating the need for set matching, simplifying maintenance and replacements. X5 belts are backside idler compatible with no significant loss in belt life, allowing for more flexible system designs.
Extended Belt Life
- X5 V-Belts resist cracking, hardening, and stretching
- EPDM compound ensures long service life, even in extreme operating conditions
- Longer operational intervals
- Fewer replacements
- Reduced downtime and maintenance costs
Unmatched Energy Efficiency
- Cogged design lowers internal friction, using 40% less energy to flex around pulleys compared to traditional designs
- 2% energy loss vs. 5%–8% for competitors
- Lower operational costs over time
- Significant annual energy savings
Wide Temperature Range
- Designed to perform reliably in extreme environments
- Operating range: -70°F to 260°F
- Maintains flexibility in cold and hot conditions
Static Conductivity & Safety Compliance
- Built to meet ARPM and Mine Safety Standards for static conductivity, making them safe for sensitive industrial environments
- Static conductive to prevent charge build-up
- Suitable for mining and explosive environments

FAQ
You Have Questions. We Have Answers.
What makes EPDM belts better?
EPDM offers superior resistance to heat, ozone, and chemical degradation. It maintains flexibility and tensile strength longer than standard rubber compounds.
What is the operating temperature range for X5 cogged belts?
The belts are rated from -70°F to 260°F, ensuring reliable performance in extreme conditions.
Are X5 cogged belts static conductive?
Yes, X5 belts meet ARPM and Mine Safety Standards for static conductivity, helping prevent static charge buildup.
What profiles and sizes are available
Standard profiles include AX, BX, CX, 3VX, 5VX, 8VX, XPZ, XPA, XPB, XPC, in both single and banded construction. Contact us for size availability.
Can I use X5 cogged belts with backside idlers?
Yes. X5 belts are engineered to work with backside idlers without significant loss in belt life.
Do X5 cogged belts require set matching?
No. X5 belts are manufactured with a one-code matching system, eliminating the need for matched sets.
Are these cogged belts made in the USA?
Yes. X5 belts are manufactured in our USA factory in Lincoln, Nebraska; ensuring the highest quality and precision.
How do X5 cogged belts improve energy efficiency?
