Overview of the Contitech AVX13X938 V‑Belt
The Contitech AVX13X938 V‑Belt is a high‑performance trapezoidal belt engineered for automotive and industrial power transmission systems. Designed to deliver reliable torque transfer, it features a precision‑cut tooth profile that ensures optimal engagement with pulleys while minimizing wear and vibration.
Design Features
The belt’s trapezoidal shape provides a large contact area between the teeth and pulley grooves, which reduces slip and enhances load capacity. The V‑shaped cross‑section also improves heat dissipation during operation, extending service life under high‑speed conditions.
Tooth Profile
The AVX13X938 incorporates a standardized tooth geometry that matches the widely used AVX series pulley system. This compatibility allows seamless integration into existing vehicle or machinery setups without requiring custom pulleys.
Material Composition
Constructed from a high‑grade rubber compound reinforced with carbon fibers, the belt offers exceptional tensile strength and resistance to abrasion. The carbon reinforcement enhances stiffness while keeping weight low, which is critical for automotive applications where mass reduction improves fuel efficiency.
Heat Resistance
The material can withstand continuous operating temperatures up to 120 °C, making it suitable for engines, alternators, and power steering systems that generate significant heat during operation.
Dimensions & Tolerances
- Belt Width (W): 13 mm
- Belt Length (L): 938 mm (nominal)
- Tooth Pitch: 6.5 mm
- Cross‑Section Height: 3.2 mm
- Tolerances: ±0.1 mm for width, ±0.2 mm for length
These precise dimensions guarantee a snug fit on standard AVX pulleys and ensure consistent performance across varying load conditions.
Application & Compatibility
The Contitech AVX13X938 V‑Belt is engineered for use in:
- Automotive power steering systems
- Alternator drives
- Air conditioning compressors
- Hydraulic pump drives
- Industrial machinery requiring high torque transfer
Its compatibility with the AVX pulley family means it can replace older or worn belts in many vehicles and machines without modification.
Installation Guidelines
- Inspect Pulley Condition: Ensure pulleys are free of cracks, burrs, or excessive wear before installation.
- Align the Belt: Position the belt on the pulleys so that the teeth face the correct direction. Misalignment can cause premature failure.
- Tension Adjustment: Use a tension gauge to achieve the manufacturer’s recommended tension range (typically 20–30 % of the belt’s breaking load).
- Check for Slack: After installation, run the system at low speed and verify that there is no excessive slack or vibration.
- Secure with Fasteners: Tighten all mounting brackets and clamps to maintain alignment during operation.
Maintenance & Care
Regular inspection is key to extending the belt’s service life:
- Check for cracking, fraying, or discoloration every 10,000 km (or equivalent operating hours).
- Ensure that the belt remains free from oil, coolant, and other contaminants that can degrade rubber.
- Re‑tension the belt if you notice a gradual loss of tension over time.
- Replace the belt if any signs of wear exceed 5 % of its original width.
Performance Benefits
The AVX13X938 V‑Belt delivers:
- High torque capacity due to its reinforced construction and large tooth contact area.
- Reduced vibration and noise, thanks to the trapezoidal profile that ensures smooth engagement.
- Improved fuel efficiency by minimizing power losses in the transmission system.
- A longer service interval compared with standard flat belts, reducing maintenance costs.

Frequently Asked Questions
- What is the difference between a V‑belt and a flat belt?
- A V‑belt has a trapezoidal cross‑section that increases contact area with pulleys, providing higher torque capacity and reduced slip compared to a flat belt.
- Can I use this belt in high‑speed applications?
- Yes. The material’s heat resistance and reinforced design make it suitable for speeds up to 3,000 rpm in automotive and industrial settings.
- How often should the belt be replaced?
- Inspect every 10,000 km or equivalent operating hours. Replace if any wear exceeds 5 % of the original width or if cracks appear.
- Is this belt compatible with all AVX pulleys?
- The AVX13X938 is designed for standard AVX pulley tooth profiles; however, always verify pulley dimensions before installation to ensure proper fit.
