FAQ

1. What are the advantages of forged aluminum pulleys over cast iron?

Forged aluminum offers:
✓ 30-50% weight reduction vs. cast iron (improves energy efficiency)
✓ Higher strength-to-weight ratio (ideal for high-RPM applications)
✓ Corrosion resistance (no rust, suitable for harsh environments)
✓ Better heat dissipation (reduces belt wear)

2. What tolerances can you achieve with CNC broaching?

• Dimensional: ±0.01mm

• Groove angle: ±0.05°

• Bore concentricity: <0.02mm TIR
  (All pulleys undergo 100% inspection with CMM)

3. Can you customize pulley groove profiles?

Yes, we support:
• Standard profiles (A/B/3L/5L/8M)
• Custom profiles (provide drawings or belt samples)
• Multi-rib combinations (e.g., dual V-grooves + flat belt sections)

4. What surface treatments are available?

5. How do you ensure dynamic balance?

• Standard: ISO 1940 G6.3 (≤2.5g imbalance at max RPM)

• Precision Grade: G2.5 available (for >8,000 RPM applications)

• Testing: Computerized dynamic balancing machines

6. What’s your MOQ and lead time?

• Bulk Orders: 1000+ pcs (30-45 days)
