# Industrial Specification: Tensioning Rollers

## 1. Technical Definition
Rollers designed to apply and maintain controlled tension on materials during processing.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-15 kN tension force, 50-500 mm roller diameter, 0.1-5 m/s linear speed**. Failure boundary: **Roller surface Hertzian contact stress exceeding 1.2 GPa for steel rollers, bearing L10 life &lt; 1000 hours at rated load**, Mechanism: **Surface fatigue spalling due to cyclic Hertzian contact stress exceeding material endurance limit, typically at 10^7 cycles for bearing steel**.

### 2.1 Analytical Physics Model
Governed by the **Tractive Power & Resistance Model**:

> **Primary Equation**: $P = \frac{F \cdot v}{\eta}$  
> **Engineering Impact**: Ensures motor torque capacity exceeds operational inertia.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| F | Total Tractive Resistance | Engineering Constant |
| v | Belt Speed | Engineering Constant |
| \eta | Efficiency | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Material yield strength degradation from work hardening exceeding 20% | 8 | Roller surface plastic deformation &gt; 0.1 mm depth | Surface hardening to 58-62 HRC with case depth 1.5-2.0 mm |
| Bearing lubrication film thickness &lt; 0.5 μm at operating temperature | 8 | Roller bearing seizure at 120°C+ temperature | Forced oil lubrication system maintaining 0.1-0.3 MPa pressure at bearing interface |
