The XCMG Spherical Bearing GE60ES with OEM number 800515285 is a heavy-duty, maintenance-required radial spherical plain bearing engineered for motor grader linkage joints, circle drive articulation points, blade lift mechanisms, and frame pivot systems. As a genuine XCMG component, this bearing accommodates substantial misalignment while supporting combined radial and axial loads in GR series graders (GR2003, GR215, GR300, GR350, GR180).
The GE60ES spherical bearing features a steel-on-steel sliding contact surface combination, consisting of an inner ring with a sphered convex outside diameter and an outer ring with a correspondingly sphered concave inside surface. The design provides a relatively low coefficient of friction combined with high load-carrying capacity and excellent wear resistance under oscillatory movement and heavy static, alternating, or impact loads.
Each bearing is manufactured from high-quality 52100 chromium bearing steel with induction-hardened sliding surfaces, providing exceptional durability. The inner and outer rings are heat-treated and protective coated for enhanced corrosion resistance. A molybdenum disulphide (MoS₂) treatment is applied to the sliding surfaces, significantly reducing friction during initial break-in and providing a solid lubricant reserve under boundary lubrication conditions.
The bearing features a single fracture in the outer ring (slotted design), which allows press-fit installation into the housing while maintaining proper radial clearance. The slotted outer ring design also accommodates slight housing bore variations without compromising the bearing’s load-carrying capacity. Both rings incorporate annular lubrication grooves and through-holes for re-lubrication, ensuring proper grease distribution across the entire sliding contact area.
The radial spherical plain bearing is specifically designed to accommodate radial loads, combined radial and axial loads, and significant misalignment between the shaft and housing. In motor grader applications, the GE60ES bearing allows angular misalignment up to 6 degrees total tilt from the central axis. This articulation capability is critical in circle drive linkages, where the blade must maintain consistent ground contact across varying terrain.
The bearing 800515285 is equally suitable for wheel loader applications; documented inquiries confirm this exact OEM number is specified for LW300KV wheel loaders. This cross-equipment compatibility demonstrates the importance of the GE60ES spherical bearing across XCMG’s heavy equipment product lines. The bearing complies with the GB/T9163-2001 Chinese national standard for spherical plain bearings, guaranteeing interchangeability with industry-standard components.
Installation of the spherical bearing 800515285 requires a press-fit into the housing bore with controlled force application. Ensure the housing bore is clean and within tolerance specifications. Align the outer ring slot away from the primary load direction when possible. Press only on the outer ring, never on the inner ring or the sliding surfaces. After installation, verify that the inner ring rotates smoothly through its full angular range without binding.
Lubrication is essential for the maintenance-required GE60ES bearing design. Initial lubrication before operation will significantly extend service life. Re-lubrication every 250–500 operating hours, depending on load severity and environmental conditions, is recommended. Use NLGI #2 lithium-based grease with EP additives and a base oil viscosity ISO VG 150–220. Apply grease slowly through the lubrication fitting until fresh grease emerges from the bearing sides.
Signs of bearing wear include increased radial play (check with a dial indicator), rough or notchy rotation, audible grinding or knocking during articulation, and visible pitting or scoring on the sliding surfaces after disassembly. If radial clearance exceeds 0.30 mm on a 60 mm bore bearing, replacement is recommended. Ignoring worn spherical bearings can lead to accelerated pin wear, housing damage, and degraded machine controllability.
Extreme temperature performance is a key attribute of the GE60ES spherical bearing. The steel-on-steel sliding contact surface assembly functions reliably from -40°C to +150°C (-40°F to +300°F). The bearing material maintains its hardness and impact resistance across this entire range, making it suitable for arctic pipeline construction, desert mining, and tropical agricultural applications without performance degradation.
Quality assurance for the 800515285 bearing includes 100% dimensional verification, Eddy current crack detection on the outer ring slot area, and sample destructive load testing per batch. ISO 9001:2024 certification is maintained throughout the manufacturing process. Each bearing is laser-marked with the OEM part number 800515285 and a batch code, ensuring full traceability back to the production lot. Bearings are individually packaged with anti-rust oil and moisture barrier protection.
For storage, keep spherical bearings in a dry, climate-controlled environment away from corrosive vapors. The original packaging should remain sealed until the time of installation. If stored for more than 24 months, inspect for surface oxidation; a light film of clean lubricating oil can be applied to prevent corrosion before use. Do not use solvent-based cleaners that could remove the MoS₂ treatment from the sliding surfaces.
In summary, the XCMG Spherical Bearing GE60ES OEM 800515285 is a mission-critical component for maintaining precise articulation, absorbing shock loads, and ensuring smooth multi-axis movement in motor grader linkage systems. Its high load capacity, substantial misalignment accommodation, robust steel-on-steel construction, and re-lubrication capability make it the correct choice for heavy earthmoving and road construction equipment. Always specify genuine XCMG 800515285 for maximum reliability, fitment accuracy, and operational uptime.

The radial spherical plain bearing is installed in critical pivot and linkage points across XCMG motor graders, including the circle drive linkage assembly, where it allows the blade to rotate while accommodating misalignment between the drawbar and the blade support structure. This bearing is also used in the blade lift hydraulic cylinder pivots, the articulation joint between front and rear frames, the front wheel lean mechanism linkage, and the ripper shank mounting connection.
In wheel loader applications, the same GE60ES spherical bearing is specified for steering knuckle linkages and boom pivot points. The bearing’s ability to accommodate angular misalignment while supporting high radial loads makes it equally effective in loader articulation systems. This cross‑platform standardization simplifies spare parts logistics for mixed XCMG fleets.

Comparative field studies conducted on GR2003 motor graders operating in high‑impact mining and road construction environments have demonstrated that genuine spherical bearings typically achieve service intervals of 5,000 to 8,000 hours before requiring replacement, while lower‑grade aftermarket bearings commonly fail between 2,000 and 3,000 hours under identical operating conditions. The difference is attributed to three factors: consistent hardening depth on the raceways, MoS₂ surface treatment integrity, and precise material composition control.
Fleet maintenance records indicate that aftermarket failures are most frequently characterized by rapid wear of the sliding surfaces, leading to excessive radial play and knocking during grader articulation. When radial clearance exceeds the recommended limit, the resulting misalignment in the circle drive linkage forces the blade to track unpredictably, reducing grading accuracy and potentially causing structural damage to linkage brackets. The genuine spherical bearing’s controlled sliding surface hardness eliminates this premature failure mode.
Press the bearing into the housing bore using a suitable press. The slotted outer ring design permits a controlled radial interference fit of 0.02–0.05 mm. Align the outer ring slot away from the primary load direction whenever possible. For circle drive applications, position the slot at a 90‑degree offset from the heaviest load. Never press on the inner ring or across the sliding surfaces, as this can indent the raceway and accelerate wear after installation.
Lubricate the bearing before initial operation using a NLGI #2 lithium‑based grease with extreme pressure additives. For moderate service environments, re‑lubricate every 250 hours of operation. For heavy‑duty applications (high shock, heavy oscillation, dusty or wet conditions), reduce the interval to 100 hours. Apply grease until fresh grease exits the sides of the bearing, ensuring that the lubrication grooves and holes are completely purged of old grease.
Routine inspection should include checking for abnormal articulation noise, measuring radial clearance with a dial indicator (bearing installed, but unloaded), and examining external signs of contamination ingress. A measured radial clearance of more than 0.30 mm for the 60 mm bore size indicates that bearing replacement should be scheduled before the next maintenance downtime. Early detection of clearance growth prevents costly bushing and pin replacement.
