# Industrial Specification: Main Roller Assembly

## 1. Technical Definition
The primary rolling mechanism in an industrial dough laminator that applies pressure to dough sheets.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 MPa (5-25 bar) at 20-40°C**. Failure boundary: **3.0 MPa pressure differential across roller surface or 0.1 mm radial deformation**, Mechanism: **Hertzian contact stress exceeding 1.5 GPa causing subsurface fatigue cracks in AISI 52100 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 |
| :--- | :--- | :--- | :--- |
| Dough hydration variation below 35% causing increased friction coefficient to 0.8 | 8 | Roller surface temperature rise to 120°C exceeding polymer seal limit | Integrated moisture sensor with PID-controlled water injection system |
| Misalignment exceeding 0.05 mm/m from foundation settlement | 8 | Edge loading producing 2.5× nominal contact stress at roller ends | Laser-aligned mounting system with quarterly 0.01 mm tolerance verification |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in the main roller assembly for food safety?
**A**: Our main roller assembly uses 304 stainless steel for all structural components and FDA-approved food-grade rubber for the compression rollers, ensuring compliance with food manufacturing hygiene standards.

### Q: How does the pressure adjustment mechanism work on this roller assembly?
**A**: The pressure adjustment mechanism uses precision threaded spindles and locking nuts to allow operators to fine-tune roller pressure from 0-1000 PSI, enabling control over dough thickness and texture during the laminating process.

### Q: What maintenance is required for the roller bearing housing?
**A**: The sealed roller bearing housing requires quarterly lubrication with food-grade grease and annual inspection for wear. The stainless steel construction resists corrosion from dough ingredients and cleaning solutions.

## 6. Manufacturing Compliance
- ISO 9001:2015 - QUALITY MANAGEMENT SYSTEMS
