Technical Specifications

Parameter Key Details
Material 6063-T6 aluminum alloy (excellent extrudability, superior surface finish for anodizing, good corrosion resistance; lightweight yet rigid for e-bike load requirements)
Processing CNC precision turning, milling, drilling, chamfering, deburring; black Type II anodizing (uniform color coverage, scratch-resistant layer); dimensional inspection with micrometers/CMM; 100% fit testing with e-bike shafts
Tolerance & Precision Inner diameter tolerance H7 (ISO standard, tight shaft fit); outer diameter tolerance ±0.01–0.02mm; length tolerance ±0.03mm; concentricity ≤0.01mm (prevents wobbling during rotation); flatness ≤0.02mm
Size Range Inner diameter: 8–30mm (fits e-bike motor shafts, handlebar stems, wheel axles); outer diameter: 15–50mm; length: 5–40mm; customizable stepped collars, flanged collars, and split collars for quick installation
Surface Finish Matte/gloss black anodizing (thickness 5–10μm, UV-resistant, no fading in outdoor use); deburred edges (smooth to touch, prevents component scratches); optional laser engraving (logo, part number, torque specs)
Mechanical Properties Tensile strength ≥207 MPa; yield strength ≥172 MPa; elongation ≥12%; operating temperature -40°C to 180°C; non-magnetic; resistant to sweat, rain, and road salt corrosion
Compatibility Fits e-bike motor shafts, front/rear wheel axles, handlebar stems, suspension forks, and battery mounting rails; compatible with standard e-bike fasteners (M5–M10 bolts); designed for press-fit or set-screw installation

Application Scenarios

  • E-Bike Motor Systems: Black anodized aluminum collars as shaft retainers for hub motors and mid-drive motors—secures components in place, prevents axial movement, and reduces vibration during high-speed riding.

  • Handlebar & Steering Systems: Precision collars for handlebar stems and headset assemblies—ensures tight fit, eliminates play in steering, and enhances ride stability.

  • Wheel & Suspension Components: Flanged collars for wheel axles and suspension forks—resists corrosion from road spray, maintains alignment, and extends service life of bearings.

  • Battery Mounting: Split aluminum collars for e-bike battery racks—allows quick battery removal/installation while keeping the mount secure during rough terrain rides.

  • OEM E-Bike Production: Standardized black anodized collars for e-bike manufacturers—consistent dimensions ensure seamless assembly, and the sleek black finish matches e-bike aesthetics.
