72349 XCMG GR2605 motor grader roller bearing
72349 roller bearing is a heavy-duty support bearing specially used for transmission, traveling and hydraulic systems of construction machinery. Adopting precision cylindrical roller structure, it mainly bears large radial load and can also bear certain axial load. The whole bearing is made of high-purity bearing steel with strict heat treatment and grinding processing. It has strong bearing capacity, high wear resistance and fatigue resistance, and can maintain stable rotation accuracy under heavy-duty, impact and vibration conditions, making it a core support component for gearboxes, differentials and wheel edge mechanisms.
Technical Parameters
- Model: 72349
- Type: Cylindrical roller bearing
- Material: High-carbon chromium bearing steel GCr15
- Surface Treatment: Precision grinding, anti-rust treatment
- Load Application: Mainly for heavy radial load, with slight axial load capacity
- Operating Temperature: -40℃～120℃
- Structure: Integrated inner & outer ring with multiple rollers, smooth rotation
- Features: Heavy-duty load capacity, wear-resistant, impact-resistant, stable clearance
Application Scenarios
Suitable for main shafts, intermediate shafts, differentials, wheel reducers, hydraulic pumps and motors in loaders, graders, rollers, forklifts and other construction machinery. Used for shaft rotation support to bear heavy radial force, adapting to harsh conditions of continuous operation, shock vibration and oil lubrication.
Common Faults & Troubleshooting
- Abnormal noise and overheating: Caused by roller wear, raceway pitting or lack of oil. Replace 72349 bearing and renew lubricating oil.
- Excessive radial clearance: Due to bearing fatigue and wear, replace with new bearing directly.
- Seizure: Caused by foreign matter intrusion or cage damage. Disassemble, clean and replace bearing.
- Uneven wear: Resulted from misalignment or overload. Replace bearing after correcting coaxiality.
