Simplify your decision with expert advice, intelligent tools, and data-driven guidance.
Choosing the right V-belt isn’t just a matter of size—it’s about matching the belt’s design and strength to your machine’s performance requirements, environmental conditions, and application.
At AIMS Industrial, we go beyond specs. We help you make confident, informed choices through a mix of expert knowledge, intelligent filtering tools, and AI-backed insights—so you get the right belt the first time.
How Do I Choose the Right V-Belt for My Application?
Start by evaluating the following:
- Load – How much power must the belt transfer?
- Speed – Is your system running at low, moderate, or high speeds?
- Pulley Size – Smaller pulleys require more flexible belts.
- Environmental Conditions – Consider heat, humidity, oil exposure, or outdoor elements.
- Manufacturer Guidelines – Always check technical specs to ensure compatibility.
What Factors Affect V-Belt Selection?
Several key variables influence which belt is best:
- Power Rating (kW or HP)
- Speed (RPM)
- Pulley Diameter & Centre Distance
- Operating Temperature
- Moisture, Dust, Oil, and Outdoor Exposure
- Shock Loads or Reversing Drives
What Is the Maximum Speed for a V-Belt Drive?
- Classic V-belts can typically run up to 30 m/s (108 km/h), depending on construction and size.
- Always verify speed ratings in the product’s technical datasheet for safety and efficiency.
What Load Can a V-Belt Handle?
The load a V-belt can handle varies based on:
- Cross-section profile (A, B, C, etc.)
- Belt material and layering
- Reinforcement cords
Heavy-duty industrial V-belts often come banded or cogged for enhanced strength. Always refer to manufacturer data for exact ratings.
Can V-Belts Be Used in Reverse Drives?
Yes—Double V-belts (hexagonal belts) are specifically designed to transmit power from both sides, making them ideal for:
- Reversible machinery
- Multi-pulley systems
- Agricultural and industrial conveyors
Are V-Belts Suitable for High-Temperature Environments?
Absolutely—but only certain models:
- Look for belts marked “heat-resistant” or with EPDM or aramid fiber construction
- These are designed to withstand 120°C+ operating conditions
Can V-Belts Be Used Outdoors?
Yes—if they're built for it:
- Wrapped V-belts with synthetic or treated fabric covers resist UV and moisture
- Weather-resistant V-belts offer protection from oil, rain, dust, and heat
When you shop with AIMS, our filters and product data help you narrow down belts designed for exterior applications.
What Is the Minimum Pulley Diameter for a V-Belt?
Using a pulley that’s too small can:
- Reduce belt life
- Cause slippage or misalignment
- Increase operating temperature
Minimum pulley diameters are defined per belt type and size.
For example:
- A-section: min. 75–100 mm
- B-section: min. 125–150 mm
Always refer to the belt’s datasheet or our team for pulley diameter guidance.
Final Thoughts
V-belt selection doesn’t have to be overwhelming. With the right understanding of your system’s speed, load, environment, and design specs, and the support of intelligent filters and AI analysis, finding the ideal belt is simple.
