· Product Overview
Introducing the YITECH Orthogonal Precision Adapter Hub — a CNC-machined monolithic component engineered for rigid, space-efficient mounting of shafts, sensors, or actuators in robotics, medical devices, optical systems, and industrial automation.
This adapter delivers:
- Solid 304 or 316L stainless steel construction (standard); optional: 6061-T6 aluminum, 17-4PH, or titanium
- Orthogonal design: Cylindrical shaft (Ø10 mm) + perpendicular mounting block (25 × 12 × 10 mm) — maximizes rigidity in confined spaces
- Two M3/M4 threaded through-holes (counterbored) on block face — for secure, low-distortion clamping
- Hollow central bore (Ø6.0 mm, depth 20 mm) — for shaft passage, fiber optic feedthrough, or fluid/gas flow
- Mirror-polished shaft + fine-machined block — Ra 0.1–0.2 μm (shaft), Ra 0.4 μm (block) — ensures smooth sliding and zero particulate generation
- Tight tolerances: ≤0.008 mm concentricity (bore to mounting face), ≤0.005 mm flatness — critical for encoder alignment and motion control
Unlike welded assemblies or stamped brackets (prone to misalignment, stress concentration, or corrosion at joints), our monolithic hub offers zero internal interfaces, superior stiffness, and long-term reliability — even under cyclic loading or in humid/sterile environments.
Ideal for engineers building collaborative robot wrists, lab automation sensors, surgical instrument drives, or compact CNC tooling where compactness, precision, and durability are non-negotiable.
