# Industrial Specification: Guide Roller

## 1. Technical Definition
A cylindrical component that directs and supports material movement along a predetermined path within machinery.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-3.0 m/s linear velocity, 50-500 N radial load, -20°C to 120°C temperature**. Failure boundary: **Bearing fatigue life L10=1,000,000 revolutions at 500 N load, surface pitting at 1.5 GPa Hertzian contact stress, seal failure at 150°C**, Mechanism: **Rolling contact fatigue from cyclic Hertzian stresses exceeding material endurance limit (typically 0.4×UTS), thermal degradation of polymer seals above glass transition temperature, abrasive wear when particle contamination exceeds ISO 4406 18/16/13 cleanliness level**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Misalignment exceeding 0.1 mm/mm over 100 mm length | 8 | Edge loading causing premature bearing raceway spalling | Integral spherical roller bearings with ±2° self-alignment capability, laser-aligned mounting fixtures with 0.02 mm precision |
| Insufficient lubrication film thickness (Λ&lt;1.0) | 8 | Metal-to-metal contact leading to adhesive wear and seizure | Forced oil circulation system maintaining 40 cSt viscosity at operating temperature, surface texturing with 5-10 μm deep dimples for lubricant retention |

## 3. Key Technical Parameters

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

### Q: What materials are best for guide rollers in corrosive environments?
**A**: Stainless steel and ceramic guide rollers offer superior corrosion resistance for harsh environments, while polyurethane provides chemical resistance and reduced material adhesion.

### Q: How do I select the right bearing type for my guide roller application?
**A**: Consider load capacity, speed, and environmental conditions. Sealed ball bearings work for most applications, while roller bearings handle heavier loads, and specialized seals protect against contaminants.

### Q: What maintenance is required for industrial guide rollers?
**A**: Regular inspection for wear, proper lubrication of bearings, checking shaft alignment, and replacing end caps/seals when damaged. Material-specific cleaning prevents buildup and extends service life.
