Product Description
Industrial Rubber V-Belt – XPA/XPB/XPC/XPZ/SPA/SPB/SPC Series, OEM Customizable
Factory Direct | Premium Rubber (NR/CR/EPDM) | Raw Edge Cogged Design | XPA/XPB/XPC/XPZ & SPA/SPB/SPC Profiles | Oil & Heat Resistant | Anti-Static (ISO 1813) | OEM Custom Length & Width | 3-Year Warranty
The Apexcoupling Industrial Rubber V-Belt series offers a comprehensive range of high-performance power transmission belts engineered for demanding industrial applications. Available in narrow wedge profiles (XPA, XPB, XPC, XPZ) and classical profiles (SPA, SPB, SPC) , these belts deliver superior power transmission efficiency, flexibility, and durability. Featuring a raw edge cogged (toothed) design, these belts provide 20-30% higher transmission capacity than conventional wrapped V-belts, run cooler on small pulleys, and offer extended service life.
Manufactured from premium rubber compounds (NR, CR, EPDM) with high-strength polyester or aramid tensile cords, these belts are oil, heat, ozone, and abrasion resistant. The anti-static design (meeting ISO 1813) safely dissipates static electricity, making them ideal for environments where static discharge poses a safety risk or can damage sensitive equipment. OEM/ODM customization is fully supported – custom lengths, widths, and profiles available.
✅ 20-30% higher transmission capacity than conventional V-belts. Raw edge cogged design – superior flexibility, runs cooler on small pulleys.

💡 Selection tip: Choose XPZ/XPA/XPB/XPC for compact, high-power drives with 50-100% higher transmission power than classical belts. Choose SPA/SPB/SPC for standard classical drives with wrapped construction.
Narrow Wedge vs Classical – Which One Do You Need?
| Feature | Narrow Wedge (XPZ/XPA/XPB/XPC) | Classical (SPA/SPB/SPC) |
|---|---|---|
| Construction | Raw edge cogged – better grip, heat dissipation | Wrapped – fabric cover |
| Power Capacity | 50-100% higher than classical belts | Standard |
| Transmission Efficiency | 15-30% higher | Good |
| Space Efficiency | Excellent – saves space in compact drives | Standard |
| Flexibility | Superior – bends around small pulleys | Moderate |
| Heat Buildup | Lower – cogs dissipate heat | Higher |
| Best for | Compact drives, high torque, high speed | Standard industrial drives |
💡 Choose narrow wedge (XPZ/XPA/XPB/XPC) for high-power, compact drives where space is limited and maximum power transmission is required. Choose classical (SPA/SPB/SPC) for standard industrial applications with wrapped belt construction.
Construction
Tensile Cord – High-strength polyester or aramid cords provide tensile strength and dimensional stability.
Rubber Compound – Premium NR, CR, or EPDM rubber with oil, heat, ozone, and abrasion resistance.
Cogged Profile (X Series) – Molded notches on the inner surface reduce bending stiffness and heat buildup.
Raw Edge (X Series) – Sidewalls without fabric covering provide direct rubber-to-pulley contact for better grip and heat dissipation.
💡 How it works: The V-belt transmits power through friction between the belt’s sidewalls and the pulley grooves. The cogged design reduces bending stiffness, allowing the belt to wrap around smaller pulleys with less heat buildup. The narrow wedge profile provides higher power capacity in a compact cross-section.

FAQ
Q: What is a cogged V-belt?
A: A cogged V-belt has molded notches (cogs) on its inner surface. The cogs increase flexibility, reduce heat buildup, and allow the belt to bend around smaller pulleys.
Q: What is the difference between XPZ and SPA?
A: Both have similar top widths (10mm vs 12.7mm). XPZ is a narrow wedge cogged belt with higher power capacity and flexibility. SPA is a classical wrapped belt with standard power capacity.
Q: What is the advantage of the narrow wedge profile?
A: Narrow wedge profiles (XPZ/XPA/XPB/XPC) provide 50-100% higher transmission power than classical belts in the same drive space.
Q: Is the belt oil and heat resistant?
A: Yes. The belts are oil, heat, ozone, and abrasion resistant, ensuring long service life in harsh industrial environments.
Q: Is the belt anti-static?
A: Yes. The belts meet ISO 1813 standards for electrical conductivity of anti-static belts.
Q: What is the temperature range?
A: The standard operating temperature range is -30°C to +100°C. Special compounds are available for extreme temperatures (-55°C to +70°C).
Q: Can the belt be customized?
A: Yes. We offer OEM/ODM customization – custom length, width, and profiles.
Q: What are the common applications?
A: Conveyors, packaging machinery, printing equipment, textile machinery, agricultural equipment, compressors, pumps, and machine tools.
Q: What is the warranty?
A: 3 Years – quality assured.
