· Product Overview
Introducing the YITECH Dual-Flange Precision Coupling Hub — a CNC-machined aluminum structural component engineered for rigid, concentric shaft coupling, optical alignment, and modular system integration in robotics, optics, medical devices, and industrial automation.
This hub delivers:
- Solid 6061-T6 aluminum construction — lightweight (2.7 g/cm³), high strength-to-weight ratio (UTS 310 MPa), non-magnetic, and thermally conductive
- Dual-flange design with 2× Ø3.5 mm through-holes per flange (for M3 screws) — enables symmetrical, low-distortion clamping
- Central hollow bore: Ø10.0 mm H7 (±0.018 mm), length 25 mm — precision passage for shafts, fibers, or fluid lines
- Clear anodized finish (Type II, 10–12 μm, sealed) — preserves natural aluminum luster while enhancing corrosion resistance and wear durability
- Tight tolerances: ≤0.006 mm concentricity (flange OD to bore centerline), ≤0.005 mm flatness — ensures zero runout under rotation
Unlike stamped steel spacers or injection-molded plastic couplings (prone to warping, inconsistent hole placement, or poor thermal stability), our dual-flange hub offers monolithic rigidity, repeatable alignment, and long-term dimensional integrity — even at 10,000+ RPM.
Ideal for engineers building servo motor couplings, microscope objective adapters, lab fluidic manifolds, or modular robotic joints where concentricity, stiffness, and clean assembly are mission-critical.

· Application Scenarios
This dual-flange coupling hub excels where rigid mounting, precise centering, and thermal stability are essential:
- Robotics & Automation
→ Motor-to-gearbox couplers (reduces backlash vs. flexible couplings)
→ Encoder mounting hubs (flanges secure to housing, bore holds shaft)
→ Collaborative robot joint spacers (lightweight + stiff) - Optics & Imaging
→ Microscope objective adapters (flanges clamp to turret, bore holds lens tube)
→ Laser diode collimator mounts
→ Fiber optic ferrule alignment sleeves - Medical Devices
→ Surgical robot drive shaft couplers
→ Lab analyzer rotor adapters
→ Infusion pump motor interfaces - Industrial Machinery
→ CNC spindle extension rings
→ Pump impeller spacers
→ Vacuum chamber feedthrough housings - Aerospace & Defense
→ UAV gimbal bearing spacers
→ Satellite actuator coupling hubs
→ Avionics sensor mounting rings
💡 Why engineers choose YITECH dual-flange hubs:
- Dual Flanges = Symmetric Clamping — eliminates cantilever stress
- H7 Bore + Clear Anodize = Optical Cleanliness — no particulates, no outgassing
- CNC from Billet = Zero Internal Stress — no warping after thermal cycling
- Custom in 5 days — no tooling fees, no minimum for bore size or flange count
