# Industrial Specification: Precision Linear Motion Guide Rail

## 1. Technical Definition
Precision linear guide component for smooth, accurate motion in industrial machinery

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 m/s linear velocity, -20°C to 80°C ambient temperature, 0.5-15 kN load capacity**. Failure boundary: **Ball/roller contact stress exceeding 3.5 GPa, surface roughness degradation below Ra 0.2 μm, lubrication film thickness below 0.1 μm**, Mechanism: **Hertzian contact fatigue at ball/rail interface due to cyclic loading exceeding material yield strength (typically 1.8 GPa for GCr15 bearing steel), boundary lubrication breakdown causing adhesive wear**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Contaminant ingress (particles &gt;5 μm) into recirculation path | 8 | Increased rolling resistance (friction coefficient &gt;0.005), premature ball/roller spalling | Integral sealing system with labyrinth seals and wipers, positive pressure purge system (0.1 bar above ambient) |
| Thermal expansion mismatch between rail (steel, α=11.5×10⁻⁶/K) and mounting surface (aluminum, α=23×10⁻⁶/K) | 8 | Rail bowing exceeding 50 μm/m length, loss of straightness accuracy (&gt;10 μm/300 mm) | Thermal compensation mounting design with differential expansion joints, controlled preload application at 20°C reference temperature |
