· Product Overview
Introducing the YITECH Precision CNC-Machined Stainless Steel Flange Hub — a robust, high-tolerance mechanical interface designed for secure shaft-to-housing coupling, motor mounting, encoder alignment, and modular assembly in industrial automation, robotics, and precision machinery.
The set includes:
- A flat flange plate (for bolt-down mounting or sealing)
- A stepped hub flange (with central shaft extension for direct shaft coupling or bearing support)
- Both feature 4× through-hole mounting pattern (on 60 mm PCD) for ISO-standard fasteners
- Mirror-finish machined surfaces with tight concentricity (≤0.015 mm runout)
- Full 360° radial symmetry for balanced rotation and vibration resistance
Crafted from AISI 304 stainless steel, these hubs deliver exceptional corrosion resistance, high strength, and long-term dimensional stability — far outperforming aluminum or cast iron in humid, chemical-exposed, or high-wear environments.
Unlike generic stamped or cast flanges, our parts are CNC-machined from solid bar stock, ensuring zero porosity, consistent wall thickness, and repeatable geometry — critical for applications where misalignment or failure is not an option.
Perfect for engineers building servo mounts, rotary encoders, pump couplings, or custom motion control subsystems.

· Application Scenarios
These flange hubs are engineered for demanding mechanical integration tasks:
- Motor & Servo Mounting
→ Direct coupling to NEMA 23/34 motors, BLDC hubs, or planetary gearheads
→ Rigid shaft alignment for high-torque applications (e.g., CNC spindles, conveyor drives) - Encoder & Sensor Integration
→ Mounting base for optical/rotary encoders (ensures zero runout for accurate feedback)
→ Reference surface for proximity sensors or limit switches - Pump & Compressor Couplings
→ Interface between pump housing and drive shaft (resists vibration and thermal cycling)
→ Sealing flange for diaphragm or gear pumps (with optional O-ring groove) - Robotics & Automation
→ Joint rotation hubs for articulated arms (with integrated bearing seats)
→ Modular end-effector adapters (quick-change tooling interfaces) - Medical & Lab Equipment
→ Centrifuge rotor mounts, pipetting system actuators, or diagnostic device spindles
→ Cleanroom-compatible (passivated, particle-free finish)
💡 Key Advantages:
- Zero warpage: Solid bar stock eliminates casting shrinkage/stress
- Interchangeable design: Standard PCD & bore sizes ensure compatibility across brands
- Long service life: Stainless steel resists galling, oxidation, and chemical exposure
- Easy assembly: Chamfered bores and countersunk holes simplify installation
