# Industrial Specification: Linear Guide Rail

## 1. Technical Definition
A precision mechanical component that provides smooth, low-friction linear motion along a fixed path.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 m/s linear velocity, -20°C to 80°C ambient temperature, 0.5-50 kN load capacity**. Failure boundary: **Ball/roller deformation at 1.5 GPa Hertzian contact stress, raceway spalling at 10⁷ stress cycles, lubricant breakdown at 120°C**, Mechanism: **Hertzian contact fatigue exceeding material yield strength (e.g., 1.2 GPa for GCr15 bearing steel), lubricant thermal degradation at Arrhenius rate constant k=1.5×10⁻⁵ s⁻¹ at 120°C**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Contaminant ingress (ISO 4406 Class 21/19/16 particles &gt;14 μm) | 8 | Three-body abrasive wear increasing coefficient of friction from 0.001 to 0.1 | Integral wiper seals with 0.05 mm labyrinth clearance, positive-pressure purge system at 0.2 bar |
| Misalignment exceeding 0.05 mm/m parallelism tolerance | 8 | Edge loading causing 2.5× stress concentration at rail ends | Kinematic mounting with 0.01 mm precision alignment pins, laser alignment verification at 632.8 nm wavelength |

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

### Q: What are the main material options for linear guide rails in machinery manufacturing?
**A**: Our linear guide rails are available in Carbon Chrome Steel (SUJ2) for high hardness and wear resistance, and Stainless Steel (SUS440C) for corrosion resistance in harsh environments.

### Q: How do the mounting holes affect installation of linear guide rails?
**A**: Precision mounting holes ensure accurate alignment and secure fastening to machinery frames, maintaining straightness and reducing vibration for optimal linear motion performance.

### Q: What maintenance do linear guide rails with seals/end caps require?
**A**: Seals and end caps protect against contaminants, extending service life. Regular cleaning and lubrication of the rail body are recommended, with minimal maintenance due to the low-friction design.
