70573 XCMG GR2605 motor grader bearing

70573 XCMG GR2605 motor grader bearing

The 70573 bearing is a general-purpose precision rolling bearing for construction machinery, primarily used for supporting rotating shafts. It can withstand radial and certain axial loads, reducing rotational friction and ensuring the coaxiality and smooth operation of components. It is a key basic component for transmission and travel mechanisms.

Technical Parameters

Model: 70573
Type: Deep groove ball bearing / Tapered roller bearing
Material: High carbon chromium bearing steel, heat-treated and hardened
Precision: Standard industrial grade, suitable for construction machinery operating conditions
Load Capacity: Primarily radial load, with axial load consideration
Operating Temperature: -30℃～120℃
Lubrication: Grease lubrication

Suitable Applications

Suitable for use in the gearboxes, drive axles, wheel assemblies, drive shafts, balance boxes, idler shafts, etc., of construction machinery such as loaders, graders, and road rollers; providing stable support for various rotating components and reducing wear and heat generation.

Common Faults and Troubleshooting

Abnormal noise, severe overheating: Insufficient grease in the bearing, raceway spalling, or impurities entering the bearing. Replace the 70573 bearing and refill with grease.

Excessive clearance and wobbling during operation: Bearing wear or fatigue loosening. Replace the bearing directly and check the shaft diameter and housing bore for proper fit.

Stuck and not rotating: Raceway jamming, corrosion, or excessive tightness. Clean the cavity and correctly assemble a new bearing.

Premature damage: Poor coaxiality, seal failure, or overload. Correct the installation position and improve sealing and lubrication.
