# Industrial Specification: Support Rollers and Thrust Rollers

## 1. Technical Definition
Critical rotating components that support and axially position the rotary drum in fertilizer granulation equipment.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **Radial load: 5-25 kN, Axial load: 2-12 kN, Rotational speed: 10-60 rpm, Operating temperature: 40-120°C**. Failure boundary: **Radial load &gt; 30 kN causes permanent bearing race deformation, Axial load &gt; 15 kN exceeds thrust bearing capacity, Temperature &gt; 150°C degrades lubricant viscosity below 68 cSt**, Mechanism: **Hertzian contact stress exceeding 1.8 GPa causes subsurface fatigue cracks in bearing races, Thermal expansion mismatch between steel rollers (α=11×10⁻⁶/°C) and polymer seals (α=80×10⁻⁶/°C) creates binding forces &gt; 500 N**.

### 2.1 Analytical Physics Model
Governed by the **Frame Structural Deflection Analysis**:

> **Primary Equation**: $\delta = \frac{5 q L^4}{384 E I}$  
> **Engineering Impact**: Ensures structural stability for multi-stage machines.

| Symbol | Variable Definition | Localized Reference |

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

### Q: What materials are used in these support and thrust rollers?
**A**: Our rollers are manufactured from premium forged alloy steel and high-carbon chromium steel for maximum durability and load-bearing capacity in demanding fertilizer granulation applications.

### Q: How do support rollers and thrust rollers function in granulation equipment?
**A**: Support rollers bear the radial load of the rotating drum, while thrust rollers provide axial positioning to prevent lateral movement, ensuring stable and efficient granulation operations.

### Q: What maintenance is required for these rotating components?
**A**: Regular inspection of tapered roller bearings, lubrication maintenance, and monitoring for wear on the outer shell/race are essential for optimal performance and extended service life.
