# Industrial Specification: Linear Bearing Block

## 1. Technical Definition
A housing unit that contains and supports linear bearings, enabling precise linear motion along a rail or shaft.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-150°C temperature, 0-1000 N radial load, 0-500 N axial load, 0-2 m/s linear velocity**. Failure boundary: **Ball deformation at 1200 MPa contact stress (Hertzian stress), cage fracture at 150°C glass transition temperature for POM, raceway spalling at 10⁷ stress cycles (ISO 14728 L10 life)**, Mechanism: **Hertzian contact fatigue from cyclic loading exceeding 1200 MPa yield strength of AISI 52100 steel, thermal expansion mismatch (Δα=11×10⁻⁶/°C steel vs 110×10⁻⁶/°C polymer) causing binding, lubricant breakdown at 150°C leading to adhesive wear**.
