  • Tensile Strength: ≥515 MPa (rigid for high-torque power transfer)
  • Corrosion Resistance: Passed 72-hour salt spray test (suitable for humid/industrial environments)
  • Food-Safe: Compliant with FDA 21 CFR 175.300 (ideal for food-processing equipment)
• Manufacturing Standard: ISO 9001-Certified
  • Key Processes: CNC Turning (flange + shaft profile) → Precision Drilling (radial positioning holes) → Deburring → Surface Passivation → CMM Inspection
  • Standard Parameters:
    • Flange Diameter: 60mm (customizable 40–80mm)
    • Shaft Diameter: 20mm (customizable 15–30mm)
    • Overall Length: 150mm (customizable 100–250mm)
    • Dimensional Tolerance: ±0.02mm (ensures precise mating with bearings, gears, and fixtures)
  • Surface Finish: Passivated polished (scratch-resistant, rust-proof, and smooth for low-wear rotation)

· Application Scenarios

• Industrial Automation: Conveyor system drive shafts, robotic arm joint positioning shafts, and gearbox output shafts.
• Medical & Laboratory Equipment: Precision instrument drive shafts (304 SS meets hygiene standards) and diagnostic machine positioning components.
• Packaging Machinery: Material feeding drive shafts, labeling machine positioning shafts, and sealing system actuation shafts.
• 3D Printing Systems: Build plate leveling drive shafts and extruder gearbox output shafts.
• Food & Beverage Processing: Sanitary conveyor drive shafts and packaging machine component shafts (compliant with food-safety regulations).

· Production Process Introduction

1. Raw Material Sourcing: Procure certified 304 stainless steel round bars (traceable to quality standards) and cut to blank length.
2. CNC Turning: Use high-precision CNC lathes to machine the integrated flange and cylindrical shaft profile in a single setup for maximum concentricity.
3. Precision Drilling: Drill radial positioning holes in the flange and shaft body for secure component locking.
4. Deburring & Finishing: Remove sharp edges from threads, holes, and flange transitions to prevent assembly damage and reduce wear.
5. Surface Passivation: Apply a chemical passivation treatment to enhance 304 SS’s natural corrosion resistance.
6. Quality Inspection: Perform CMM dimensional scanning, thread fit testing, and surface finish analysis to verify compliance with design specifications.

· Packaging and Shipping Methods

• Packaging:
  • Individual Pairs: Protected with anti-scratch foam padding, sealed in moisture-proof plastic bags, and packed in labeled cardboard boxes (marked “Paired Flange Drive Shafts”).
  • Bulk Orders: Secured in foam-lined wooden crates with additional bracing to prevent shaft deformation during transit.
• Shipping Options:
  • Express Delivery (DHL/FedEx): 3–5 business days for prototype or small-quantity orders.
  • Air Freight: 7–10 business days for medium-batch production runs.
  • Sea Freight: 20–25 business days for large-volume bulk orders.All shipments include full tracking and damage insurance.

· Frequently Asked Questions (FAQ)

• MOQ (Minimum Order Quantity): 500 paired sets for standard configurations; 200 pairs for custom designs (with valid technical drawings).
• Lead Time: Standard lead time is 7–10 working days (includes CNC machining and passivation); expedited production (5–7 working days) is available for urgent orders (additional fees apply).
• Customization Capability: Full customization is supported—adjust flange diameter, shaft length, positioning hole size, or switch to 316 stainless steel (for extreme corrosion environments). Our engineering team validates designs for load capacity and component fit.
