# Industrial Specification: Bearing Assembly

## 1. Technical Definition
A mechanical assembly within a furniture hinge that facilitates smooth rotational movement and reduces friction between moving parts.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-120°C temperature, 0-50 N·m torque, 0-1000 rpm rotational speed**. Failure boundary: **Lubricant breakdown at 150°C, bearing seizure at 80 N·m torque, surface pitting at 10^7 stress cycles**, Mechanism: **Hertzian contact stress exceeding 1.5 GPa causes subsurface fatigue cracks; lubricant thermal degradation at Arrhenius rate constant k=1.2×10^4 s^-1**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Contaminant ingress (particle size &gt;5 μm) exceeding ISO 4406 18/16/13 cleanliness level | 8 | Abrasive wear increasing surface roughness Ra &gt;0.8 μm | Integrate labyrinth seals with 0.1 mm clearance and IP65-rated housing |
| Misalignment exceeding 0.05° angular deviation from shaft axis | 8 | Edge loading causing localized stress concentration Kt=3.2 | Implement self-aligning spherical bearing design with ±2° compensation |

## 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**: **CNC Machining Center**, **Surface Grinding Machine**, **Heat Treatment Furnace**  
**Downstream Applications**: Office Chair Swivel Mechanism, Cabinet Door Hinge Assembly, Recliner Tilt Mechanism  

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

### Q: What materials are best for bearing assemblies in furniture manufacturing?
**A**: Stainless steel offers corrosion resistance for high-moisture environments, carbon steel provides durability for heavy-duty applications, brass reduces noise, and polymers like POM or nylon offer lightweight, self-lubricating options with low friction.

### Q: How does a bearing assembly improve furniture hinge performance?
**A**: The bearing assembly facilitates smooth rotational movement between hinge parts, reduces friction to prevent wear, minimizes noise during operation, and extends the lifespan of the furniture hinge by distributing load evenly across rolling elements.

### Q: What maintenance do furniture bearing assemblies require?
**A**: Most bearing assemblies in furniture are sealed or shielded to prevent contamination and require minimal maintenance. For unsealed types, periodic cleaning and lubrication with appropriate grease may be needed depending on material and usage frequency.

## 6. Manufacturing Compliance
- ISO 15:2011 (ROLLING BEARINGS - RADIAL BEARINGS - BOUNDARY DIMENSIONS, GENERAL PLAN)
- ANSI/ABMA 9:1990 (LOAD RATINGS AND FATIGUE LIFE FOR BALL BEARINGS)
- DIN 620-1:2012 (ROLLING BEARINGS - RADIAL BEARINGS - BOUNDARY DIMENSIONS, GENERAL PLAN)
