The 800515224 Bearing 61904 is manufactured under strict ISO 9001:2015 quality controls. Each bearing undergoes 100% inspection for dimensional accuracy, radial runout, and noise level (vibration grade Z2/V2). This ensures that the bearing operates quietly and smoothly even at high rotational speeds, critical for grader transmission and wheel hub applications.
Deep groove ball bearings like the 61904 are designed to accommodate both radial and moderate axial loads in either direction. The 800515224 bearing features an optimized internal geometry that reduces friction torque by up to 12% compared to generic alternatives, contributing to lower fuel consumption and cooler running temperatures.
XCMG graders operate in demanding environments — from road construction to mining sites. The 800515224 bearing is sealed with high-quality rubber seals (2RS option) that prevent dust, mud, and moisture ingress. This extends the maintenance interval significantly, reducing downtime for fleets.
The bearing rings and balls are made from vacuum-degassed GCr15 chrome steel, which provides excellent wear resistance and fatigue life. After heat treatment, the surface hardness reaches HRC 60–64, while the core retains toughness. The 800515224 bearing also features a stabilized dimensional treatment, making it suitable for operating temperatures from -30°C to +120°C.
Installing the genuine 800515224 bearing ensures that your grader’s drive train, idler pulleys, or gearbox operate with minimal vibration. The precise internal clearance (C3 clearance standard) accommodates thermal expansion under heavy loads, preventing premature seizure. Many aftermarket bearings fail due to incorrect clearance — the 800515224 eliminates this risk.
In field tests on XCMG GR180 graders, the 800515224 bearing showed a service life of over 8,000 operating hours in heavy-duty earthmoving applications, outperforming non-OEM bearings by 40%. This translates to fewer repairs, lower parts consumption, and higher resale value for your machinery.
Direct replacement for XCMG part number 800515224. No modifications required, perfect alignment with housing and shaft.
Limiting speed up to 18,000 rpm with grease lubrication, suitable for high-rotation components in grader transmissions.
Optional rubber seals (2RS) provide IP67-level dust/water resistance, ideal for muddy or dusty job sites.
Vibration grade Z2 ensures low noise and smooth operation, reducing operator fatigue and improving comfort.
Always handle the 800515224 bearing with clean tools and avoid impacts. Before installation, inspect the shaft and housing for burrs or damage. Apply a thin layer of clean grease to the mating surfaces. Use a press-fit tool on the ring that is being press-fitted (never apply force through rolling elements).
For XCMG grader wheel hubs, torque the retaining nut to the manufacturer’s specification (usually 200–250 Nm). After assembly, rotate the hub by hand to ensure no binding. Grease replenishment intervals depend on operating conditions; in normal use, re-grease every 1,500 hours with NLGI #2 lithium-based grease.
If you detect unusual noise, vibration, or heat during grader operation, inspect the 800515224 bearing immediately. Early replacement prevents damage to adjacent components such as shafts, housings, and seals. Keep spare bearings in original packaging in a dry, clean environment.
Counterfeit bearings often use inferior steel, incorrect geometry, and poor heat treatment, leading to sudden failure that can damage the entire grader assembly. The genuine 800515224 Bearing 61904 comes with full traceability, laser-etched part number, and certification of conformance. XCMG dealers and authorized distributors stock this exact bearing to ensure your machinery meets original performance standards.
By selecting the OEM 800515224, you benefit from extended warranty coverage and access to technical support. The bearing’s raceway surface finish (Ra ≤ 0.1 µm) reduces micro-welding and smearing, critical for start-stop operations common in grader fine-grading applications.
For fleet managers and maintenance engineers, standardizing on the 800515224 bearing reduces inventory complexity. One part number fits multiple XCMG grader models (GR135 to GR260) and also applies to certain XCMG loaders and rollers. This simplifies spare parts management and reduces the risk of misordering.
