# Industrial Specification: Motion Guide / Bearing

## 1. Technical Definition
A mechanical component that provides precise linear or rotational guidance and reduces friction between moving parts in sorting mechanisms.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 m/s linear velocity, -40°C to 120°C temperature, 0.5-50 kN load capacity**. Failure boundary: **Surface contact pressure exceeding 2.5 GPa (Hertzian stress limit), lubricant film thickness &lt;0.1 μm (λ ratio &lt;1), raceway Brinell hardness reduction to &lt;58 HRC**, Mechanism: **Adhesive wear from boundary lubrication breakdown at λ&lt;1, subsurface fatigue cracking at shear stress &gt;0.55×yield strength, thermal softening at &gt;150°C for steel alloys**.

### 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.

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

### Q: What materials are best for motion guide bearings in corrosive environments?
**A**: Stainless steel motion guide bearings offer superior corrosion resistance for wet or chemically exposed sorting mechanisms, while chrome steel provides optimal hardness for standard industrial applications.

### Q: How do end seals improve bearing performance in sorting equipment?
**A**: End seals prevent contamination from debris and retain lubrication, extending bearing life and maintaining precision in high-cycle sorting operations where particulate contamination is common.

### Q: What maintenance is required for motion guide bearings in continuous operation?
**A**: Regular lubrication inspection and periodic cleaning of guide rails are essential. Most industrial motion bearings require lubrication every 3-6 months depending on load and operating environment.

## 6. Manufacturing Compliance
- ISO 14728-1:2004 (ROLLING BEARINGS - LINEAR MOTION ROLLING BEARINGS)
- ANSI/ABMA 9:1990 (LOAD RATINGS AND FATIGUE LIFE FOR BALL BEARINGS)
- DIN 636:2017 (LINEAR BALL BEARINGS AND SHAFT ASSEMBLIES)
