· Product Overview

· Core Specifications

• Materials:
  • 304 Stainless Steel: Ideal for general industrial 传动 systems (excellent corrosion resistance, high tensile strength).
  • 316 Stainless Steel: Optimized for sterile/harsh environments (enhanced corrosion resistance, biocompatibility for medical equipment).
• Manufacturing Standard: ISO 9001-Certified CNC Turn-Mill Machining Process
  • Key Processes: CNC turning (flange + outer profile) → CNC milling (internal splined bore + positioning tab) → Surface passivation (corrosion protection) → Deburring.
  • Tolerances: ±0.02mm (ensures spline mesh accuracy); internal spline complies with DIN 5480 (standard metric spline specification).
  • Torque Capacity: Up to 50 N·m (varies by size; customizable for higher loads).

· Application Scenarios

• Industrial Automation: Connecting motor shafts to gearboxes, conveyor drive components, or robotic arm actuators.
• Precision Machinery: Torque transfer in 3D printer extruder drives, CNC router spindle connections, or lab equipment 传动 modules.
• Medical Equipment: Sterile torque connections in diagnostic tool motors or surgical instrument drive systems (316 stainless steel option).
• Aerospace & Defense: Lightweight, high-strength shaft connections in avionic sensor actuators or small vehicle 传动 assemblies.
• Custom Mechanical Builds: Hobbyist robotics drive systems, custom gearbox components, or workshop tool 传动 joints.

· Production Process Introduction

1. Raw Material Sourcing: Procure certified 304/316 stainless steel bars (metallurgically tested for torque resistance and purity).
2. CNC Turning: Machine the flange, outer cylindrical profile, and base features to exact dimensional specs.
3. CNC Turn-Mill Machining: Mill the internal splined bore (matches standard spline profiles) and integrated positioning tab (for assembly alignment).
4. Surface Passivation: Apply a chemical treatment to enhance the stainless steel’s natural corrosion resistance.
5. Quality Inspection: Verify spline accuracy (via spline gauges), conduct CMM scans for dimensional tolerance, and test torque capacity.
6. Packaging Preparation: Wrap the hub to protect the passivated surface and splined bore.

· Packaging and Shipping Methods

• Packaging: Individual hubs are sealed in anti-scratch, dust-proof plastic bags (to protect the splined bore); bulk orders are packed in foam-lined partitioned boxes (prevents spline damage and deformation).
• Shipping: Flexible logistics options:
  • Express Delivery (DHL/FedEx/UPS: 3–5 business days)
  • Air Freight (7–10 business days)
  • Sea Freight (20–30 business days)All shipments include full tracking and damage insurance.

· Frequently Asked Questions (FAQ)

• MOQ (Minimum Order Quantity): 100 pieces for standard designs; small sample packs (5–10 pieces) are available for fit/torque testing.
• Lead Time: Standard lead time is 7–12 working days after order confirmation; expedited production (5–7 working days) is available for urgent orders (additional fees apply).
• Customization Capability: Full OEM/ODM customization is supported—we can adjust hub size, spline specification (metric/imperial), flange design, torque capacity, or material grade (304 vs. 316) based on your technical drawings. Our engineering team will validate design feasibility for torque transfer performance.
