# Industrial Specification: Linear Guides

## 1. Technical Definition
Precision mechanical components that provide 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, lubricant film breakdown at λ&lt;1.0 (film thickness ratio), recirculation jam at 0.01 mm particle ingress**, Mechanism: **Hertzian contact fatigue at ball/raceway interfaces (σ_max &gt; 1.5 GPa), boundary lubrication failure (λ&lt;1.0) causing adhesive wear, particle-induced three-body abrasion (hardness ratio &gt;0.8)**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Lubricant starvation (oil film thickness &lt;0.1 μm) | 8 | Adhesive galling at ball/raceway interface (coefficient of friction &gt;0.3) | Forced lubrication system with 0.2 MPa minimum pressure and 5 μm filtration |
| Misalignment exceeding 0.02 mm/100 mm | 8 | Edge loading causing localized Hertzian stress &gt;2.0 GPa | Self-aligning carriage design with ±0.5° angular compensation |

## 5. Engineering Risks & FAQ

- **Caution**: 

### Q: What are the main components of a linear guide system?
**A**: A linear guide system consists of four key components: the carriage (slider block) that moves along the rail, the rail itself which provides the fixed path, recirculating ball bearings for smooth motion, and end seals to protect against contamination.

### Q: Which material is best for corrosive environments?
**A**: Stainless steel linear guides are ideal for corrosive or washdown environments due to their excellent corrosion resistance, while aluminum alloy offers good corrosion resistance with lighter weight for applications where weight reduction is important.

### Q: How do recirculating ball bearings improve linear motion?
**A**: Recirculating ball bearings reduce friction by allowing balls to circulate continuously between the carriage and rail, providing smoother motion, higher precision, longer service life, and greater load capacity compared to traditional sliding contact designs.

## 6. Manufacturing Compliance
