· Product Overview
Introducing the YITECH Precision Aluminum Keyed Shaft Hub — a CNC-machined structural adapter engineered for rigid coupling, rotational indexing, and secure mounting in high-performance motion control, automation, and optical systems.
This hub delivers:
- Solid 6061-T6 aluminum construction — lightweight (2.7 g/cm³), strong (UTS 310 MPa), non-magnetic, and thermally conductive (167 W/m·K)
- Radial linear knurling on top surface — enhances grip during manual assembly and provides a premium visual identity (no paint or coating — natural Al texture)
- Integrated functional geometry:
- Central square recess with keyway slot (DIN 6885, standard width 4 mm) for keyed shaft alignment
- Cylindrical bore (Ø12 mm standard) for precise shaft fit (H7 tolerance)
- 4× Ø4 mm through-mounting holes (PCD 40 mm) for bolted fixation
- Side hole (Ø2.5 mm) for set screw, oiling, or sensor integration
- Tight tolerances: ±0.005 mm on bore ID, ≤0.008 mm concentricity — ensures zero runout and repeatable angular positioning
Unlike stamped steel plates or injection-molded plastic hubs (prone to flex, misalignment, or wear), our hub offers monolithic rigidity, zero assembly drift, and verified torque capacity — even under cyclic loads up to 200 N·m.
Ideal for engineers building servo motor interfaces, lab automation stages, laser galvo mounts, or custom 3D printer extruder carriers.

· Application Scenarios
This keyed hub excels where rotational indexing, torque transmission, and precise mounting are critical:
- Motion Control & Robotics
→ Servo motor to gearbox coupling hubs (keyway prevents slippage)
→ Encoder/resolver mounting bases with angular zero reference
→ Collaborative robot joint adapters - Optics & Laser Systems
→ Galvo mirror mounts with indexed rotation (keyway = repeatable 0° position)
→ Fiber optic rotary joints (bore for ferrule, knurl for hand-tightening)
→ Beam steering stage hubs - 3D Printing & CNC
→ Extruder drive hubs (keyed to motor shaft for zero backlash)
→ Spindle collet adapters for mini-CNCs
→ Tool changer interfaces - Medical Devices
→ Surgical robot wrist modules
→ Lab centrifuge rotor adapters
→ Imaging system rotation stages - Consumer & Pro Audio
→ High-end turntable platter hubs (knurl = premium tactile feel)
→ Studio monitor calibration rotors
→ VR headset gimbal mounts
💡 Why engineers choose YITECH keyed hubs:
- Keyway + bore = true zero-backlash coupling — no elastic deformation under load
- Radial knurl = functional aesthetics — improves grip and brand perception
- CNC from billet = zero internal stress — no warping after thermal cycling
- Custom in 5 days — no tooling cost, no minimum for keyway size or hole pattern
