Product No.: 330105-02-10-20-00 - General Introduction
This product is a precisely configured mounting flange or spacer hub, likely part of a modular system for aligning and securing components on a shaft. The shortened suffix sequence (compared to the 6-segment version) suggests it is a standardized, off-the-shelf variant with fewer configurable options. It is designed to provide a rigid interface with specific outer dimensions and a central bore, facilitating accurate mounting of gears, pulleys, bearings, or sensors in mechanical assemblies.
Detailed Parameters
| Parameter Category | Specification | Details / Notes |
|---|---|---|
| Central Bore / Shaft Size | 10 mm | The "-10-" segment specifies the nominal inner diameter for mounting on a 10mm shaft. Tolerance is likely standard (e.g., H7). |
| Primary Outer Diameter (O.D.) | Approx. 20 - 25 mm | The "-20-" segment directly indicates the outer diameter, which is likely 20 mm. This is a compact, precision-sized hub. |
| Overall Thickness / Width | Approx. 5 - 10 mm | Standard width for a flange of this diameter, providing sufficient material for structural integrity and mounting screw engagement. |
| Mounting Feature | Likely through-holes or a specific bolt pattern. | The "-00" ending suggests either no secondary mounting holes (a simple spacer) or a default, standard hole pattern (e.g., two M3 tapped holes on a P.C.D.). |
| Material | Precision-machined Aluminum Alloy (6061-T6) (Most Common) | Offers an excellent strength-to-weight ratio, good machinability, and corrosion resistance. Stainless steel is a possible alternative. |
| Surface Finish | Natural (Clear) Anodized or Black Anodized. | Anodizing provides surface hardness, wear resistance, and protection against oxidation. |
| Weight | Approx. 5 - 15 grams | Extremely lightweight due to aluminum construction and compact size. |
| Key Feature | Precision-Machined Concentricity. | The bore and outer diameter are machined to be highly concentric, ensuring minimal runout when used as a mounting reference. |
| Runout / Tolerance | < 0.02 mm TIR (Typical) | Critical for applications requiring high rotational accuracy. |
| Potential Secondary Features | May include a light press fit on the bore, a small chamfer on edges, or a flat surface for set screw engagement (implied by the "02" prefix in 330105-02). |
Primary Application Scenarios
This compact, precision hub is used in applications requiring accurate component positioning on a standard 10mm shaft.
Precision Robotics & Automation:
Small Timing Pulley Hub: Serves as the interface to mount a GT2 or HTD timing pulley (with a 20mm outer hub) onto a 10mm motor or idler shaft, ensuring perfect alignment for synchronous belt drives.
Optical & Laboratory Equipment:
Lens or Filter Mount Adapter: Acts as a precision spacer or adapter to mount optical elements or rotary filter wheels to the shaft of a small stepper motor or manual rotary stage.
3D Printer & Desktop CNC Mechanics:
Direct Drive or Idler Bearing Mount: Used to secure a ball bearing (with a 20mm O.D.) onto a 10mm smooth rod or lead screw, creating a low-friction linear motion carriage or a bearing block for a leadscrew nut.
Sensor & Encoder Mounting:
Proximity Sensor Bracket: The flange can be used as a fixed mounting point to bracket a small inductive or optical sensor next to a rotating 10mm shaft for speed or position detection.
General Mechanical Prototyping & Fixturing:
Precision Spacer / Shims: Used as a high-accuracy, reusable spacer between components on a shaft (e.g., between two bearings o
