# Industrial Specification: Bearing/Housing

## 1. Technical Definition
A mechanical assembly that supports and positions a rotating shaft while reducing friction and wear.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-150°C temperature, 0-10000 rpm rotational speed, 0-200 MPa contact stress**. Failure boundary: **L10 life exceeded (90% reliability at 1 million revolutions), Brinell hardness reduction &gt;15%, radial clearance &gt;0.1 mm**, Mechanism: **Hertzian contact stress exceeding material yield strength (σ_max &gt; σ_yield), adhesive/abrasive wear from boundary lubrication breakdown, fatigue spalling from subsurface crack propagation**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Insufficient lubrication film thickness (λ &lt; 1.0) | 8 | Metal-to-metal contact causing adhesive wear and seizure | Forced oil circulation system with minimum 0.025 mm film thickness, surface roughness Ra &lt; 0.4 μm |
| Misalignment exceeding 0.05 mm/mm | 8 | Edge loading and premature fatigue failure | Self-aligning spherical roller bearings, precision machined housing with 0.01 mm flatness tolerance |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |
| :--- | :--- | :--- | :--- |
| spec | Config-dependent | mm | Verified |

## 4. System BOM & Knowledge Routing
### Core Components (Recursive Links)

### Industrial DNA Context (De-duplicated)
**Complementary Dependencies**: **Shaft Alignment Laser System**, **Industrial Grease Lubricator**, **Vibration Analysis Equipment**  
**Downstream Applications**: Industrial Pumps, Electric Motors, Conveyor Systems  

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

### Q: What materials are commonly used in bearing/housing assemblies for machinery manufacturing?
**A**: Bearing/housing assemblies typically use bearing steel for rolling elements and rings, cast iron for durable housing bodies, and aluminum alloy for lightweight applications where corrosion resistance is needed.

### Q: What are the main components in a bearing/housing assembly BOM?
**A**: The bill of materials includes: Inner Ring, Outer Ring, Rolling Elements (like balls or rollers), Cage/Retainer to separate elements, Seals/Shields for contamination protection, and Housing Body for structural support.

### Q: How does a bearing/housing assembly reduce friction in rotating machinery?
**A**: It uses precision-engineered rolling elements between inner and outer rings to minimize surface contact, distributing loads smoothly while the housing maintains proper alignment, significantly reducing friction and wear on shafts.

## 6. Manufacturing Compliance
- ISO 15:2011 (RADIAL BEARINGS - BOUNDARY DIMENSIONS, GENERAL PLAN)
