| Feature | Technical Details | Core Advantages |
|---|---|---|
| Precision Internal Spline Bore | Customizable internal spline profile (DIN/ISO standards) with tight tolerance control (IT6-IT7) | Delivers zero-slip, high-torque power transmission; ensures precise angular positioning and concentricity |
| Axial Clamping Slot | Precision-machined slot for quick clamping and locking | Enables fast installation/removal; prevents loosening under vibration or shock loads |
| Multi-Groove Pulley Body | Optimized V-groove/synchronous belt groove design (customizable pitch/width) | Compatible with V-belts, synchronous belts, or timing belts; maximizes power transmission efficiency |
| High-Performance Materials | - Engineering plastics: POM/PA66-GF/PEEK (self-lubricating, noise-reducing)- Metal: Black anodized aluminum/blackened steel (high strength, heat resistance) | Tailored material options to match your application’s load, temperature, and chemical resistance requirements |
| Precision Surface Finish | Mirror-polished or matte black finish (Ra ≤ 0.2μm for plastic, Ra ≤ 0.4μm for metal) | Ensures smooth belt operation, reduces wear, and enhances corrosion resistance |
| Customizable Dimensions | Flexible outer diameter, groove pitch, spline count, and bore size | Fully OEM/ODM compatible to fit your unique design specifications |
| Parameter | Standard Configuration | Customization Options |
|---|---|---|
| Product Type | Pulley with internal spline & clamping slot | Custom groove profiles, spline types, and mounting interfaces |
| Material Options | - Engineering Plastic: POM, PA66-GF20, PEEK- Metal: 6061-T6 Al (black anodized), 45# Steel (blackened) | Special grades for high-temperature, chemical-resistant, or food-contact applications |
| Outer Diameter (OD) | Customizable (e.g., 30mm–100mm) | Any dimension per your 2D/3D drawing |
| Bore Size (Spline) | Customizable (e.g., 8mm–30mm) | Metric/imperial spline standards (DIN 5480, ISO 14, ANSI B92.1) |
| Groove Type | V-belt / Timing belt / Synchronous belt | Custom pitch, depth, and number of grooves |
| Surface Finish | Matte black (standard) / High-gloss black | Custom colors, laser marking, or part number engraving |
| Tolerance | ±0.01mm (critical features) | Higher precision classes for ultra-demanding applications |
| Certifications | ISO 9001, RoHS, REACH | Automotive-grade certifications (IATF 16949) available upon request |

Precision Engineering: Our components are produced using high-precision CNC machining or injection molding with advanced mold flow simulation, ensuring dimensional accuracy and consistency across all parts.
Clean Production Environment: All parts are manufactured in a controlled environment to prevent contamination, with ultrasonic cleaning and visual inspection for every batch.
Rigorous Testing: Each component undergoes dimensional verification (CMM/optical scanner), torque fatigue testing, and material property analysis to meet your performance requirements.
Design Optimization: Our engineering team refines your design for manufacturability (DFM), reducing costs while improving performance and regulatory compliance.
Material Selection: We help you choose the optimal material grade to balance strength, weight, and environmental resistance.
Mold/Tooling Development: Custom multi-cavity molds and CNC tooling for high-volume production.
Branding & Traceability: Laser engraving, mold-in logos, and lot number marking for full traceability.
Unmatched Precision: Micron-level tolerances ensure zero backlash and consistent performance.
Application Expertise: Decades of experience in industrial and automotive components, with a proven track record of successful OEM partnerships.
Quality Assurance: ISO 9001 certified production with 100% inspection before shipment.
Cost Efficiency: High-volume production capabilities and optimized design reduce per-unit costs without compromising quality.
Global Support: End-to-end engineering and logistics support for customers worldwide, including expedited prototype and sample runs.
