Product No.: 330173-00-07-10-02-05 - General Introduction
This product is a precision, dual-clamping shaft collar with an anti-rotation grub screw, designed for secure and repeatable axial positioning on a shaft. It belongs to a modular system of mechanical components where the part number defines its exact specifications. The structure suggests it incorporates two distinct locking mechanisms: a primary radial clamping system and a secondary anti-rotation feature, making it ideal for applications where both axial movement and rotational slippage must be absolutely prevented under high loads or vibration.
Detailed Parameters
| Parameter Category | Specification | Details / Notes |
|---|---|---|
| Bore Size (I.D.) | 7 mm | The "-07-" segment specifies the precise inner diameter for mounting on a 7mm shaft. Tolerance is typically h6 or h7 for a precise sliding fit before clamping. |
| Outer Diameter (O.D.) | Approx. 12 - 15 mm | The "-10-" commonly refers to a standard outer diameter or series size, resulting in a compact yet robust profile. |
| Width / Thickness | Approx. 5 - 8 mm | Standard width providing sufficient material for the dual clamping mechanisms. |
| Primary Clamping | Single-Piece, Radial Clamp (Screw Type) | The "-02-" often indicates a single socket head clamp screw, tightened radially to create friction-based holding force. |
| Secondary Locking | Grub Screw (Anti-Rotation Pin) | The "-05" suffix is critical and typically specifies an additional grub screw (dog point or cup point) oriented axially into a pre-drilled dimple or flat on the shaft. This positively prevents rotational slippage. |
| Screw Sizes | Clamp Screw: Likely M3 Grub Screw: Likely M2 or M2.5 | Sized appropriately for the collar dimensions. |
| Primary Material | Black-Oxide Alloy Steel (e.g., 12L14) or Stainless Steel (303/304) | Most common for high strength and durability. Provides excellent clamping force and wear resistance. |
| Finish | Black Oxide (for steel) or Passivated (for stainless). | Provides corrosion resistance and a low-reflectivity surface. |
| Weight | Approx. 3 - 7 grams | Lightweight but solid due to its small size and steel construction. |
| Key Feature | Dual-Security Locking | Combines: 1. Radial Friction Clamp: For strong axial holding. 2. Positive Mechanical Lock (Grub Screw): For absolute rotational security. |
| Runout / Concentricity | < 0.02 mm TIR | Precision-machined to ensure minimal runout for balanced operation. |
| Installation Note | Requires a prepared shaft with a matching dimple or flat for the grub screw to engage. | Essential for the anti-rotation feature to function correctly. |
Primary Application Scenarios
This component is critical in applications where both axial position and angular orientation must be permanently fixed, especially under dynamic loads.
Precision Robotics & Automation Arms:
Timing Pulley/Hub Locking: Used to secure timing pulleys or gears to motor shafts in robot joints. The radial clamp provides axial fixation, while the grub screw ensures the pulley cannot rotate even a fraction of a degree relative to the shaft, maintaining critical timing belt alignment.
CNC Machine Tool Spindles & Accessories:
Tool Holder & Adapter Positioning: Acts as a secure stop collar on drawbars, tool changers, or coolant delivery tubes. The dual lock prevents any creeping or rotation induced by high spindle speeds and vibrations.
Optical & Laser System Mounts:
Mirror & Lens Cell Adjustment Lock: After fine-tuning the axial position of an optical element on a post or shaft, this collar locks it in place. The grub screw ensures the optical axis does not rotate out of alignment.
High-Performance RC & Drone Drivetrains:
Pinion Gear Security: Used to mount brass or steel pinion gears onto high-RPM brushless motor shafts. The combination lock prevents gear slippage under extreme acceleration/deceleration and eliminates the need for adhesives.
Scientific Instrumentation & Test Equipment:
Shaft Position Lock for Sensors/Encoders: Provides a rigid, non-slip mounting point for rotary encoders, resolvers, or other sensing devices on a shaft, ensuring the angular reference remains stable over time.
