# Industrial Specification: Guiding Roller Assembly

## 1. Technical Definition
A mechanical assembly of rollers used to guide and control the lateral position of continuous web materials during processing.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-5.0 m/s web speed, 10-100 N lateral tension, -20°C to 120°C ambient temperature**. Failure boundary: **Roller bearing seizure at 150°C lubricant breakdown temperature, 0.3 mm lateral misalignment causing web tracking deviation, 200 N lateral force causing structural deformation**, Mechanism: **Bearing lubricant thermal degradation following Arrhenius equation with activation energy 80 kJ/mol, Hertzian contact stress exceeding 1.2 GPa causing subsurface fatigue cracks, misalignment-induced edge loading creating 3:1 stress concentration factor**.

### 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.
