# Industrial Specification: Spool Holder

## 1. Technical Definition
A mechanical component designed to securely hold and support a spool of wire or cable, allowing for controlled unwinding during dispensing operations.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-150 N·m torque, 0-50 kg load, -20°C to 80°C temperature**. Failure boundary: **Material yield strength threshold: 250 MPa for steel, 50 MPa for aluminum; Bearing fatigue limit: 10^7 cycles at 100 N radial load**, Mechanism: **Stress concentration at spool flange mounting points exceeding material yield strength; Bearing raceway spalling due to Hertzian contact stress exceeding 1.5 GPa**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Radial load exceeding 150 N during high-speed unwinding | 8 | Bearing seizure causing rotational lock | Angular contact ball bearings with 200 N dynamic load rating and 0.05 mm radial clearance |
| Corrosive environment with chloride concentration &gt; 100 ppm | 8 | Stress corrosion cracking at spool mounting bolt holes | AISI 316 stainless steel construction with 3 mm corrosion allowance and cathodic protection at -0.85 V vs SCE |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |

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

### Q: What materials are best for heavy-duty spool holders in manufacturing environments?
**A**: For heavy-duty applications, steel or aluminum alloy spool holders offer maximum durability and load capacity, while reinforced plastic provides corrosion resistance for lighter operations.

### Q: How do I ensure smooth unwinding during cable dispensing operations?
**A**: Incorporate high-quality bearings or bushings in the shaft/spindle design to reduce friction, and use adjustable retaining mechanisms to maintain proper tension during unwinding.

### Q: Can this spool holder accommodate different spool sizes?
**A**: Yes, our spool holders feature adjustable mounting brackets and interchangeable collars/clips to securely hold various spool diameters commonly used in manufacturing.
