# Industrial Specification: Carriage / Slide Block

## 1. Technical Definition
A moving component that travels along a linear rail, providing precise linear motion and load support.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-100 m/s linear velocity, -20°C to 80°C ambient temperature, 0-1000 N dynamic load**. Failure boundary: **Ball bearing fatigue at 10⁷ stress cycles (ISO 281 L10 life), recirculation system failure at 0.5 mm particle contamination, rail surface spalling at 1.8 GPa Hertzian contact stress**, Mechanism: **Micro-spalling initiates at subsurface maximum shear stress τ_max = 0.31p₀ (Hertz theory) where p₀ exceeds material yield strength; recirculation jam occurs when contaminant diameter &gt; ball-raceway clearance (typically 5-15 μm)**.

### 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.

- **Caution**: 

### Q: What materials are available for carriage/slide blocks and which should I choose?
**A**: Our carriage/slide blocks come in carbon steel (for maximum strength and cost-effectiveness), stainless steel (for corrosion resistance in harsh environments), and aluminum alloy (for lightweight applications requiring reduced inertia). Choose based on your load requirements, environmental conditions, and weight constraints.

### Q: How do recirculating ball bearings in slide blocks improve performance?
**A**: Recirculating ball bearings provide smooth, low-friction linear motion with high precision and load capacity. They distribute loads evenly across multiple bearing points, reduce wear, and maintain accuracy over extended use, making them ideal for repetitive industrial applications.

### Q: What maintenance do carriage/slide blocks require for optimal operation?
**A**: Regular lubrication through the fitting port is essential to minimize friction and wear. End seals/wipers should be inspected periodically to prevent contamination from dust and debris. For continuous operation in demanding environments, we recommend scheduled maintenance every 6-12 months depending on usage intensity.
