# Industrial Specification: Reel Spindle

## 1. Technical Definition
The central rotating shaft in a vibratory bowl feeder or reel stand that holds and dispenses material reels or spools.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **300-1800 RPM at 0.5-2.5 N·m torque**. Failure boundary: **Exceeds 2000 RPM with 3.0 N·m torque or operates below 200 RPM with 0.3 N·m torque**, Mechanism: **Bending fatigue failure due to combined torsional and bending stresses exceeding the yield strength of AISI 4140 steel (415 MPa) at critical cross-sections**.

### 2.1 Analytical Physics Model
Governed by the **L10 Bearing Life & Fatigue Model**:

> **Primary Equation**: $L_{10} = (\frac{C}{P})^p$  
> **Engineering Impact**: Predicts mechanical lifecycle before component fatigue.
