Product No.: 330105-02-12-10-12-05 - General Introduction
This product is a specialized adapter flange or mounting hub, designed for precise interface conversion and component integration within a modular mechanical system. The part number structure indicates it is a multi-attribute component, likely serving as a rigid interconnect between a shaft and a larger assembly, or between two subsystems with different mounting patterns. The suffix "-05" typically denotes an anti-rotation or keyed feature.
Detailed Parameters
| Parameter Category | Specification | Details / Notes |
|---|---|---|
| Central Bore / Interface | 12 mm | The "-12-" segment specifies the primary through-hole or mounting shaft diameter. |
| Mounting Flange Pattern | Circular, with multiple tapped holes | The "-10-" and "-12-" segments likely define the bolt circle diameter (e.g., 10mm or 12mm B.C.D.) and the number/size of mounting holes (e.g., M3 or M4). |
| Primary Outer Diameter | Approx. 25 - 30 mm | Inferred from the 12mm bore and typical flange proportions. |
| Overall Thickness / Height | Approx. 8 - 12 mm | Provides structural rigidity for secure mounting. |
| Key / Anti-Rotation Feature | Keyway (Parallel Key) or Pin Slot | The "-05" suffix strongly indicates an integrated keyway (likely for a 4mm wide parallel key on the 12mm bore) or a provision for a dowel pin to prevent relative rotation. |
| Mounting Screw Specification | Likely M3 or M4 socket head cap screws | Used to secure the flange to a mating surface. The "-12-" may specify screw size or quantity. |
| Primary Material | Precision-machined Aluminum Alloy (6061-T6) | Standard for high strength-to-weight ratio, dimensional stability, and corrosion resistance in precision assemblies. |
| Surface Finish | Natural Anodized (Clear) or Black Anodized | Anodizing enhances surface hardness and provides a protective, wear-resistant layer. |
| Weight | Approx. 15 - 35 grams | Weight varies based on exact dimensions and material density. |
| Key Feature | Precision Interface Conversion | Acts as a transition piece, translating a 12mm shaft connection to a specific bolt pattern, while positively locking against rotation. |
| Concentricity / Flatness | High Precision (< 0.03 mm runout) | Critical to ensure mounted components run true without introducing misalignment. |
| Secondary Features | May include alignment dowel holes, counterbores for screw heads, or threading on the central bore. | Specified by the detailed suffix sequence. |
Primary Application Scenarios
This component is essential for creating robust, repeatable mechanical interfaces in precision systems.
Motor-to-Machine Coupling Integration:
Encoder or Resolver Mounting Flange: Used to mount a rotary encoder or resolver onto the rear shaft extension of a servo motor. The flange bolts to the motor face, the central bore fits the shaft, and the keyway ensures accurate angular alignment for feedback.
Optical & Photonics Equipment:
Lens Holder or Filter Wheel Adapter: Serves as the mounting interface between a rotary stage (with a 12mm output shaft) and a lens holder or multi-position filter wheel. The precise bolt pattern and keyway ensure optical axis alignment.
Industrial Automation & Robotics:
Custom Tooling Adapter on Robot Wrist: Acts as a transition plate between a standardized robot tool flange and a custom end-effector. The central bore and keyway may interface with a pneumatic or electrical rotary union.
3D Printer & CNC Upgrades:
Direct Drive Extruder Mounting Hub: Converts the shaft of a high-torque stepper motor (e.g., with a 12mm D-cut shaft) to a specific bolt pattern for attaching a direct-drive extruder assembly, with the keyway preventing torque slippage.
Test & Measurement Fixturing:
Rotary Sensor Calibration Fixture: Used as a precisely machined reference hub in fixtures for calibrating torque sensors or angular encoders, where the mounting pattern and keyway define the reference plane and orientation.
