| Parameter | Value | Unit | Notes |
|---|---|---|---|
| Inner Diameter | 26 | mm | Shaft compatibility and fit |
| Outer Diameter | 32 | mm | Housing and envelope constraints |
| Load Rating Dynamic | 5 | kg2 | Repetitive operation basis |
| Load Rating Static | 20 | kg | Peak or safety margin load |
| Typical Application | Linear guides, small actuators | - | Compact motion systems |
Dimensional Analysis and Tolerance
Interpreting 26mm32mm
The figures 26mm32mm specify the critical bore and outside diameters that dictate fit, alignment, and envelope. Tolerance ranges, surface finish, and roundness should be verified against the associated drawing and standard manufacturing classes to avoid premature wear or binding in guided assemblies.
Dynamic Load Capacity 5kg2
Understanding the Rating
The notation 5kg2 indicates a dynamic load capacity referenced to squared acceleration units, commonly used in motion and bearing standards. This rating helps predict service life under cyclic loading, where repeated shock and vibration could exceed basic static limits.
Static Load and Safety Factor
Design Margin for 20kg
The 20kg static rating represents the maximum load the component can withstand without permanent deformation. Engineers apply safety factors to this value, considering peak forces, misalignment, and environmental conditions to ensure robust system reliability.
Integration and Mounting Considerations
Optimizing Fit and Performance
Proper installation practices are essential to realize the stated 5kg2 20kg capabilities. Key actions include accurate shaft preparation, controlled press fit procedures, alignment checks, and lubrication protocols that preserve dimensional integrity over the product lifecycle.
Operational Guidelines and Recommendations
- Verify shaft and housing tolerances against the 26mm32mm dimensions before assembly.
- Apply aligned mounting forces to prevent raceway damage and preserve the 5kg2 dynamic rating.
- Implement regular lubrication intervals to control wear and extend the life derived from the 20kg static capacity.
- Monitor operating temperatures and vibrations to detect early signs of fatigue or misalignment.
