# Industrial Specification: Hydraulic Actuators

## 1. Technical Definition
Hydraulic-powered devices that convert fluid pressure into mechanical motion to control mandrel positioning and force application.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **5-350 bar**. Failure boundary: **420 bar (seal extrusion limit for HNBR seals at 100°C)**, Mechanism: **Cavitation-induced erosion at fluid velocities exceeding 15 m/s causes pitting on piston surfaces, leading to seal failure and pressure loss**.

### 2.1 Analytical Physics Model
Governed by the **Thin-Wall Pressure Vessel Stress Analysis**:

> **Primary Equation**: $\sigma_h = \frac{P \cdot D}{2t}$  
> **Engineering Impact**: Determines the hoop stress boundary to prevent rupture.
