This article provides a practical guide on how to choose the right FAG spherical roller bearing, including specifications, popular models, application insights, and tips for selection.
🔍 Understanding FAG Spherical Roller Bearings
FAG spherical roller bearings are self-aligning, double-row bearings designed to handle high radial loads and moderate axial loads, even under shaft misalignment and shock conditions. Their barrel-shaped rollers and robust cages ensure long service life in industries such as mining, cement, steel, paper, and power generation.
🛠️ Key Specifications to Consider
When selecting a FAG spherical roller bearing, consider the following parameters:
| Specification | Description |
|---|---|
| Bore Size (d) | Diameter of the inner bore (e.g., 90mm, 100mm, 125mm) |
| Outer Diameter (D) | Outer ring diameter (varies by model) |
| Width (B) | Total bearing width |
| Clearance (C3, C4, etc.) | Internal space for thermal expansion or speed requirements |
| Cage Type | Options include brass cage (MA), sheet steel, or polyamide |
| Bore Type | Cylindrical or tapered (K) for press or adapter mounting |
| Special Features | Vibration resistance (T41A), high-temp stability, etc. |

✅ How to Choose the Right FAG Bearing
-
Determine Load Requirements – Analyze both radial and axial loads.
-
Check Alignment Conditions – Opt for spherical bearings if shaft misalignment is common.
-
Assess Operating Temperature – Choose the correct clearance and cage material.
-
Consider Vibration & Shock – Use T41A-coded models for dynamic machinery.
-
Size & Mounting Needs – Pick the appropriate bore type (cylindrical or tapered) for your mounting system.
