# Industrial Specification: Chuck Assembly

## 1. Technical Definition
A mechanical assembly within a capping head that grips and holds caps during the capping process.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 NÂ·m torque, 0.1-0.3 mm concentricity tolerance, 15-35Â°C ambient temperature**. Failure boundary: **3.0 NÂ·m torque causes permanent deformation of gripping jaws, 0.4 mm concentricity deviation causes cap misalignment, 40Â°C causes thermal expansion exceeding 0.05 mm clearance**, Mechanism: **Yield strength of 4140 steel (415 MPa) exceeded at 3.0 NÂ·m, Hertzian contact stress at jaw-cap interface exceeds 600 MPa at 0.4 mm misalignment, coefficient of thermal expansion (11.7 Î¼m/mÂ·Â°C) causes interference fit above 40Â°C**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.
