When sourcing pulleys (including V-belt pulleys, timing belt pulleys, and other types), providing accurate technical specifications ensures you get the right component for your application. Below are the essential data points suppliers need to meet your requirements:
1. Basic Pulley Specifications
- Type of Pulley:
- V-belt pulley / Timing belt pulley (e.g., HTD, GT2, T5) / Flat belt pulley / Variable speed pulley.
- Belt Compatibility:
- Specify belt profile (e.g., A-section, B-section for V-belts; 8M, 5M for timing belts).
2. Critical Dimensions
- Bore Diameter:
- Shaft size (e.g., 10mm, 1/2 inch) and keyway specifications (if applicable).
- Outside Diameter (OD):
- Determines speed ratio; for timing pulleys, specify pitch diameter.
- Number of Grooves/Teeth:
- For multi-groove V-pulleys or timing pulleys (e.g., 3-groove, 20 teeth).
- Face Width:
- Width of the pulley (e.g., 20mm, 3/4″).
3. Material & Construction
- Material:
- Aluminum (lightweight), cast iron (durability), steel (high load), or plastic (corrosion-resistant).
- Surface Treatment:
- Anodizing (aluminum), powder coating, or black oxide finish.
4. Performance Requirements
- Speed (RPM):
- Maximum operational speed to ensure balance and safety.
- Torque/Load Capacity:
- Expected load to verify pulley strength.
- Environment:
- Exposure to chemicals, moisture, or high temperatures.
5. Mounting & Customization
- Hub Type:
- Solid hub, split taper bush (e.g., QD bushing), or flanged design.
- Special Features:
- Set screws, pilot holes, or dynamic balancing for high-speed applications.
Why This Matters
Providing these details avoids:
✔ Mismatched components (e.g., wrong belt profile).
✔ Mechanical failures (under-sized pulleys for high loads).
✔ Delivery delays (back-and-forth clarifications).
Pro Tip: Include a sketch or CAD drawing for custom pulleys to eliminate guesswork.
