72293 XCMG GR2605 motor grader bearing
72293 is a tapered roller bearing (inner ring/cone) for construction machinery, suitable for heavy load, impact and vibration conditions. It is mainly used in transmission systems, wheels, differentials and planetary mechanisms to withstand combined radial and axial loads, ensuring rotation accuracy and transmission stability.
Technical Parameters
- Model: 72293
- Type: Tapered Roller Bearing (Inner Ring/Cone)
- Material: High-carbon chromium bearing steel (GCr15) with quenching and tempering
- Surface Treatment: Precision grinding, anti-rust treatment
- Accuracy Grade: P0/P6, meeting construction machinery standards
- Load Characteristics: High radial and axial load capacity, impact resistant
- Operating Temperature: -40℃～120℃
- Structure: Separable inner ring, used with matching outer ring/roller set
Application Scenarios
Suitable for wheels, drive axles, differentials, planetary reducers, drive shafts and steering mechanisms of construction machinery such as loaders, graders, rollers, forklifts and aerial work platforms; used for heavy-duty rotation support, axial positioning and clearance compensation.
Common Faults & Troubleshooting
- Wear looseness and abnormal noise: Caused by excessive fitting clearance or poor lubrication. Replace 72293 bearing and inspect matching outer ring and roller set.
- Raceway pitting and spalling: Caused by overload or impact. Replace the complete bearing set and check load and installation issues.
- Overheating and burning: Caused by excessive preload or lubrication failure. Readjust clearance and replace grease.
- Rust and seizure: Caused by damp and dusty environment. Replace the complete set if unusable after cleaning.
