Definition
Bearing reconditioning is the process of restoring worn or damaged bearings to regain their functional properties, precision, and reliability. It includes inspection, repair, and returning the bearing to operational condition while maintaining technical tolerances.
Features
- Extends bearing service life
- Reduces costs compared to full replacement
- Restores functional surfaces and tolerances
- Enables retention of original bearing specifications
- Environmentally sustainable solution
- Especially suitable for special and large-size bearings
Applications
- Aerospace and space industries
- Power generation and turbine systems
- Industrial gearboxes and drive systems
- Large-scale and specialized bearings
- Applications requiring high precision and limited spare part availability
Reconditioning Process
Inspection and Diagnosis
- Visual inspection and wear measurement
- Geometric, roundness, and surface analysis
- Evaluation of bearing suitability for reconditioning
Restoration of Functional Surfaces
- Grinding and superfinishing of raceways
- Repair or replacement of rolling elements
- Adjustment of clearance and preload
Assembly and Testing
- Clean-room assembly
- Dimensional and tolerance checks
- Vibration and functional testing
Conclusion
Bearing reconditioning is a technically and economically efficient method to restore bearing performance without complete replacement. When done properly, it can deliver operational reliability comparable to that of a new bearing.
