Overview
Static limiting load diagrams are used to:
- Check if the selected bearing size is suitable under mainly static load conditions
- Determine the tilting moment MK that the AXRY bearing can support in addition to the axial load
Important Note
The static limiting load diagrams incorporate the static load safety factor S0 ≥ 4 as well as the screw and bearing ring strength.
How to Use Load Diagrams
Step 1: Determine Load Type
- Fa - Axial load [kN]
- Fr - Radial load [kN]
- M - Tilting moment [kNm]
Step 2: Calculate Equivalent Load
If there is a tilting moment, it needs to be converted to an equivalent axial force:
Where dpw is the rolling element pitch circle diameter.
Step 3: Check Load Diagram
In the corresponding size load diagram, confirm that the (Fr, Fa,eq) point is within the permitted range.

Recommended Safety Factors
| Operating Conditions | Static Safety Factor S0 |
|---|---|
| Normal smooth operation | 1.5 - 2.0 |
| Light shock or vibration | 2.0 - 3.0 |
| Moderate shock loads | 3.0 - 4.0 |
| Severe shock loads | 4.0 - 5.0 |
| High precision requirements | ≥ 3.0 |
Important Notes
- Temperature Effects - High temperature operation reduces material strength; allowable load should be appropriately reduced
- Dynamic Loads - For dynamic operating conditions, use dynamic load ratings for life calculations
- Preload Effects - Preload reduces available external load capacity
- Installation Errors - Installation errors generate additional internal loads
