Product Description

Industrial Rubber V-Belt – XPA/XPB/XPC/XPZ/SPA/SPB/SPC/A/B/C Series

The Apexcoupling Industrial Rubber V-Belt series offers a comprehensive range of high-performance power transmission belts engineered for reliable, efficient operation in demanding industrial applications. Available in both wrapped (SPA/SPB/SPC/A/B/C) and cogged (XPA/XPB/XPC/XPZ) constructions, these belts deliver precise transmission, excellent abrasion resistance, and high tensile strength across a wide range of operating conditions.

Manufactured from premium natural rubber / neoprene with high-strength polyester tension cords and a durable fabric cover, these belts offer exceptional resistance to oil, heat, ozone, and abrasion. The narrow wedge profile provides up to 50% higher power capacity than classical V-belts, making them the ideal choice for applications where space, weight, and power capacity are critical.

Available in a comprehensive range of profiles – XPZ (10mm), XPA (13mm), XPB (16-17mm), XPC (22mm), SPA (13mm), SPB (17mm), SPC (22mm), A (13mm), B (17mm), and C (22mm) – with OEM/ODM customization for custom lengths and widths. Ideal for air compressors, cooling fans, conveyors, cement mixers, pumps, crushers, textile mills, and general industrial drives.

✅ Up to 50% higher power capacity than classical V-belts. Wrapped & cogged options – choose the right construction for your application. Oil, heat, ozone & abrasion resistant – long service life.

Wrapped vs Cogged – Which Construction Do You Need?

Feature	Wrapped V-Belt (SPA/SPB/SPC/A/B/C)	Cogged V-Belt (XPA/XPB/XPC/XPZ)
Construction	Full fabric wrap – protects against abrasion and debris	Raw edge with molded cogs – increased flexibility
Flexibility	Standard	Superior – bends around small pulleys [3†L24-L26]
Heat Buildup	Standard	Lower – cogs dissipate heat [3†L24-L25]
Power Capacity	Standard	20-30% higher than wrapped belts [2†L20-L21]
Small Pulley Operation	Limited	Excellent – reduced bending stress [3†L26]
Best for	Standard drives, harsh environments, debris-prone areas	Compact drives, small pulleys, high speeds, high efficiency

💡 Choose wrapped (SPA/SPB/SPC/A/B/C) for standard industrial applications where abrasion protection is critical. Choose cogged (XPA/XPB/XPC/XPZ) for compact drives, small pulleys, high-speed applications, and maximum power transmission efficiency [2†L20-L21][3†L24-L26].

Product Structure

Tensile Cord – High-strength polyester cords provide tensile strength, low stretch, and dimensional stability [7†L14].
Rubber Compound – Premium natural rubber / neoprene with oil, heat, ozone, and abrasion resistance.
Fabric Cover – Durable fabric wrap protects the belt core from abrasion, debris, and oil (wrapped construction).
Cogged Profile (X Series) – Molded notches on the inner surface reduce bending stress and heat buildup [3†L24-L26].
40° Wedge Angle – Provides optimal grip and power transmission efficiency.

💡 How it works: The V-belt transmits power through friction between the belt’s sidewalls and the pulley grooves. The narrow wedge profile provides a larger contact area with the pulley, enabling higher power transmission in a more compact space. Cogged belts (X series) feature molded notches that reduce bending resistance, allowing operation on smaller pulleys with less heat buildup [3†L24-L26].

FAQ

Q: What is the difference between XPA and SPA V-belts?
A: Both have similar dimensions (13mm top width, 10mm height). XPA is a cogged (raw edge) belt with molded notches for increased flexibility and heat dissipation [3†L24-L26]. SPA is a wrapped belt with a full fabric cover for enhanced abrasion protection [5†L20-L22].

Q: What is the advantage of cogged V-belts (X series)?
A: Cogged belts have molded notches that reduce bending resistance, allow operation on smaller pulleys, run cooler, and provide 20-30% higher power capacity than wrapped belts [2†L20-L21][3†L24-L26].

Q: What are the applications for these belts?
A: Air compressors, conveyors, cooling fans, cement mixers, pumps, crushers, textile mills, printing equipment, packaging machinery, agricultural machinery, and HVAC systems.

Q: Are these belts oil and heat resistant?
A: Yes. The belts are oil, heat, ozone, and abrasion resistant, with an operating temperature range of -30°C to +100°C (EPDM options available from -50°C to +130°C).

Q: Are these belts anti-static?
A: Yes. The belts meet ISO 1813 standards for anti-static belts.

Q: Can the belts be customized?
A: Yes. We offer OEM/ODM customization – custom length, width, and profiles available.

Q: What is the warranty?
A: 3 Years – 100% free replacement for any quality issues.
