# Industrial Specification: Bearing Assemblies

## 1. Technical Definition
Mechanical assemblies that support rotating shafts and reduce friction in milling drums

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-150°C temperature, 0-10000 rpm rotational speed, 0-50 kN radial load, 0-25 kN axial load**. Failure boundary: **Lubricant film thickness &lt; 1 μm (boundary lubrication regime), contact stress &gt; 2.5 GPa (yield strength of bearing steel), temperature &gt; 150°C (lubricant breakdown)**, Mechanism: **Hertzian contact stress exceeding material yield strength causes plastic deformation; lubricant film collapse due to high temperature or insufficient viscosity leads to metal-to-metal contact and adhesive wear**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Contaminant ingress (particles &gt; 10 μm) | 8 | Surface indentation and fatigue spalling | Integral sealing with IP67 rating, positive pressure lubrication system with 5 μm filtration |
| Lubricant starvation (flow rate &lt; 0.5 L/min) | 8 | Thermal runaway and seizure | Redundant lubrication circuits with flow sensors and temperature feedback control |

## 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**: **Lubrication System**, **Vibration Monitoring System**, **Alignment Laser System**  
**Downstream Applications**: Industrial Milling Machines, Paper Manufacturing Equipment, Mining Conveyor Systems  

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

### Q: What materials are used in your bearing assemblies for high-temperature applications?
**A**: For high-temperature or corrosive environments, we offer bearing assemblies made from stainless steel or specialized ceramic materials, which provide superior heat resistance and durability compared to standard bearing steel.

### Q: How do seals and shields in bearing assemblies improve machinery performance?
**A**: Seals and shields in our bearing assemblies prevent contamination from dust, debris, and moisture while retaining lubrication, reducing maintenance needs and extending the lifespan of milling drums and rotating shafts.

### Q: Can you customize bearing assemblies for specific machinery requirements?
**A**: Yes, we provide custom bearing assemblies tailored to your machinery specifications, including adjustments in materials (like ceramic for specialized uses), dimensions, load capacities, and seal types to optimize performance in your equipment.
