· Product Overview

· Core Specifications

• Material: 6061-T6 Aluminum Alloy
  • Density: 2.7g/cm³ (lightweight for reduced system inertia)
  • Tensile Strength: ≥290 MPa (rigid enough for positioning and load support)
  • Thermal Conductivity: 167 W/m·K (excellent for heat dissipation in continuous operation)
  • Corrosion Resistance: Enhanced via natural anodization (scratch-proof and fade-resistant)
• Manufacturing Standard: ISO 9001-Certified
  • Key Processes: CNC Turning (stepped profile + flange) → Precision Drilling (internal bore) → Deburring → Natural Anodization → CMM Inspection
  • Standard Parameters:
    • Outer Diameter (Flange): 18mm (customizable 12–25mm)
    • Stepped Body Diameter: 12mm / 10mm (customizable to assembly needs)
    • Internal Bore Diameter: 8mm (customizable 5–15mm)
    • Dimensional Tolerance: ±0.01mm (ensures precise mating with shafts and components)
  • Surface Finish: Natural anodized (50–80μm thickness; corrosion-resistant and smooth for low-wear operation)

· Application Scenarios

• Industrial Automation: Conveyor system shaft guides, robotic joint positioning bushings, and sensor mounting adapters.
• 3D Printing Equipment: Extruder component bushings, build plate alignment sleeves, and linear system spacers.
• Electronics & Gadgets: PCB positioning bushings, enclosure panel alignment sleeves, and small device internal mounts.
• Hobby & DIY Projects: RC vehicle suspension bushings, custom jig positioning components, and robotics low-friction spacers.
• Medical & Laboratory Devices: Diagnostic instrument component mounts, sample handling bushings, and calibration tool positioning sleeves.

· Production Process Introduction

1. Raw Material Preparation: Cut 6061-T6 aluminum bars into cylindrical blanks matching the bushing’s overall length.
2. CNC Turning: Use high-precision CNC lathes to machine the stepped cylindrical profile and integrated flange in a single setup for maximum concentricity.
3. Precision Drilling: Create the hollow internal bore to reduce weight while maintaining structural rigidity.
4. Deburring & Finishing: Remove sharp edges from the flange, stepped transitions, and bore surfaces to prevent component wear and ensure safe handling.
5. Natural Anodization: Submerge the bushings in electrolytic baths to enhance corrosion resistance and surface durability.
6. Quality Inspection: Perform CMM dimensional scanning, bore fit testing, and surface finish analysis to verify compliance with design specifications.

· Packaging and Shipping Methods

• Packaging:
  • Individual Pairs: Wrapped in anti-scratch foam padding, sealed in moisture-proof plastic bags, and labeled with size specifications for traceability.
  • Bulk Orders: Packed in foam-lined partitioned boxes (prevents bushing deformation, scratch damage, and mixing of sizes).
• 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 anodization); expedited production (5–7 working days) is available for urgent orders (additional fees apply).
• Customization Capability: Full customization is supported—adjust flange diameter, stepped body sizes, bore dimensions, or switch to 7075 aluminum for higher load capacity. Our engineering team validates designs for fit and load-bearing performance.
