# Industrial Specification: Linear Guide Blocks

## 1. Technical Definition
Precision components that slide along linear guide rails to provide smooth, low-friction motion in mechanical systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 m/s sliding velocity, -20°C to 80°C ambient temperature, 0.5-50 kN load capacity**. Failure boundary: **Surface contact pressure exceeding 250 MPa, sliding velocity exceeding 120 m/s, contamination particle size &gt; 5 μm entering raceway**, Mechanism: **Hertzian contact stress exceeding material yield strength (typically 600-800 MPa for hardened steel), lubricant film breakdown at λ &lt; 1 (Stribeck curve), abrasive wear from hard particle ingress**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Insufficient lubrication film thickness (λ &lt; 1) | 8 | Metal-to-metal contact causing adhesive wear and increased friction coefficient from 0.001 to &gt;0.3 | Forced lubrication system with 0.1-0.3 μm filtered oil at 0.1-0.3 MPa pressure, surface roughness Ra &lt; 0.1 μm |
| Misalignment exceeding 0.02 mm/100 mm | 8 | Edge loading causing localized contact stress &gt; 400 MPa and premature raceway spalling | Precision mounting surfaces with flatness &lt; 0.01 mm/m, alignment dowels with H7/g6 tolerance fit |

- **Caution**: 
- **Caution**: 

### Q: What materials are linear guide blocks typically made from?
**A**: Linear guide blocks are commonly manufactured from carbon steel for durability, stainless steel for corrosion resistance, and engineering plastics for reduced weight and noise in specific applications.

### Q: How do lubrication ports function in linear guide blocks?
**A**: Lubrication ports allow for regular greasing or oiling of internal components like ball retainers, ensuring smooth operation, reducing friction, and extending the service life of the guide block and rail system.

### Q: What are the key components in a linear guide block BOM?
**A**: A typical bill of materials includes the ball retainer for smooth rolling motion, end seals to protect against contaminants, mounting holes for secure installation, and lubrication ports for maintenance.
