Precision Forged Aluminum V-Groove Pulley – Custom CNC Broaching &
Multi-Rib Design
Product Overview
Our high-performance forged aluminum V-groove pulley is
precision-engineered for demanding industrial applications.
Manufactured using CNC machining and broaching processes, it
ensures superior dimensional accuracy, durability, and smooth power
transmission in belt-driven systems.
Key Features & Benefits
✔ Premium Forged Aluminum Construction – Offers high
strength-to-weight ratio, corrosion resistance, and long-term
reliability.
✔ Precision CNC Machining – Ensures tight tolerances (±0.01mm) and
consistent groove geometry for optimal belt grip.
✔ Broaching-Type Multi-Rib Design – Enhances belt traction, reduces
slippage, and improves efficiency in high-torque applications.
✔ Customizable Specifications – Available in various sizes, rib
counts (3-12 ribs), and bore configurations (keyway, taper lock,
etc.).
✔ Wide Compatibility – Designed for automotive, industrial
machinery, HVAC systems, and agricultural equipment.

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?
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?
| Treatment | Benefits | Thickness |
|---|
| Hard Anodizing | Wear resistance (HV >500) | 25-50μm |
| Black Oxide | Anti-corrosion + aesthetics | 5-10μm |
| Nickel Plating | Chemical resistance | 10-30μm |
| As-Machined | No treatment (cost-saving) | N/A |
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
