# Industrial Specification: Linear Guide / Slide

## 1. Technical Definition
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 contact stress exceeds 3.5 GPa (yield strength of bearing steel), linear velocity exceeds 2 m/s without lubrication, contamination particle size &gt; 5 μm enters raceway**, Mechanism: **Hertzian contact stress exceeding material yield strength causes plastic deformation of raceways; boundary lubrication failure at high velocity leads to adhesive wear; abrasive wear from hard particle contamination exceeding clearance tolerances**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Insufficient lubrication film thickness (λ &lt; 1) at 1.5 m/s linear velocity | 8 | Metal-to-metal contact causing adhesive wear and increased friction coefficient from 0.001 to 0.1 | Forced lubrication system maintaining minimum 10 μm oil film thickness at all operating velocities |
| Hard particle contamination (silicon carbide, 10 μm) entering ball-raceway interface | 8 | Three-body abrasive wear creating 15 μm deep grooves in raceway surface | Multi-stage filtration system maintaining ISO 4406 cleanliness code 14/11/8 with 4 μm absolute filters |

- **Caution**: 

### Q: What materials are best for corrosive environments in linear guides?
**A**: Stainless steel linear guides offer superior corrosion resistance for humid or chemical environments, while alloy steel with proper coatings provides cost-effective protection in moderate conditions.

### Q: How do I maintain linear guides in heavy machinery applications?
**A**: Regular inspection of seals/wipers, proper lubrication of rolling elements, and checking rail alignment prevents premature wear. End caps should be monitored for debris accumulation in high-particulate environments.

### Q: What factors determine load capacity in linear slide systems?
**A**: Load capacity depends on rail material strength, carriage design, rolling element type/size, and mounting configuration. Carbon steel typically offers highest load ratings, while proper BOM component matching ensures optimal performance.
