# Industrial Specification: Industrial Dough Sheeter Roller Assembly

## 1. Technical Definition
Precision roller assembly for industrial dough sheeting and thickness control.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-5.0 mm roller gap, 0.5-3.0 m/min linear speed, 20-80°C dough temperature**. Failure boundary: **Roller deflection exceeding 0.05 mm at center under 500 N/m linear load, or surface temperature exceeding 120°C**, Mechanism: **Hertzian contact stress exceeding 800 MPa causing subsurface fatigue cracks, combined with thermal expansion mismatch between stainless steel rollers (α=17×10⁻⁶/°C) and bronze bearings (α=18×10⁻⁶/°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.
