# Industrial Specification: Linear Guide / Bearing System

## 1. Technical Definition
A precision mechanical system that provides smooth, low-friction linear motion along a defined axis.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 m/s linear velocity, -20°C to 80°C ambient temperature, 0.5-50 kN load capacity**. Failure boundary: **Contact stress exceeding 2.5 GPa at ball/raceway interface, lubricant film thickness below 0.1 μm, vibration amplitude exceeding 5 μm RMS at 1000 Hz**, Mechanism: **Hertzian contact fatigue at ball/raceway interface due to cyclic loading exceeding material yield strength, boundary lubrication failure when λ ratio (film thickness/surface roughness) &lt;1, resonance-induced fretting wear at natural frequency harmonics**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$  
> **Engineering Impact**: Calculates centrifugal force for vibratory sifters/feeders.

### Q: What are the main advantages of using hardened bearing steel in linear guide systems?
**A**: Hardened bearing steel (like GCr15/52100) provides exceptional wear resistance, high load capacity, and extended service life in demanding industrial applications, maintaining precision over millions of cycles.

### Q: How do I choose between ball bearings and roller bearings for my linear guide application?
**A**: Ball bearings offer lower friction and higher speeds, ideal for precision positioning. Roller bearings provide higher load capacity and rigidity, better for heavy-duty applications with significant moment loads.

### Q: What maintenance is required for linear guide systems in machinery manufacturing?
**A**: Regular lubrication of the rail and bearings, periodic cleaning of wipers/seals to prevent contamination, and inspection for wear on carriage blocks and rail surfaces. Most systems require minimal maintenance when properly installed.

## 6. Manufacturing Compliance
