The XCMG 800515284 spherical bearing features a robust outer ring with a spherically contoured inner surface matched with a precision ball-shaped inner ring. This unique geometry enables automatic compensation for angular misalignments caused by frame flex or mounting inaccuracies.
Advanced heat treatment ensures uniform hardness across contact surfaces, drastically reducing wear even under cyclic shock loads. Unlike generic bearings, this OE-specific part provides optimized radial internal clearance (C3 grade) that suits heavy construction machinery.
Additionally, the non-metallic sliding layer? Actually, the bearing integrates a hardened steel-on-steel sliding contact with a special anti-friction coating to minimize stick-slip and improve control precision when grading or leveling.
In grader applications, the 800515284 spherical bearing primarily connects the circle turn mechanism and the drawbar. It also supports blade lift cylinders and articulation joints, enduring multi-directional loads and vibration.
When the moldboard encounters uneven terrain, the bearing’s self-aligning capability allows continuous ground contact without binding. This prolongs the life of hydraulic components and linkage pins. Machine operators notice reduced play and more responsive blade angle adjustments.
For mining, road construction, and heavy infrastructure projects, genuine XCMG spherical bearings ensure 3000+ operational hours before replacement under normal conditions. OEM design guarantees exact fit, eliminating modification costs and downtime.
Prior to installation, inspect the housing bore and shaft for burrs or scratches. Clean thoroughly and apply a thin film of anti-seize compound on outer diameter to prevent fretting corrosion. Press-fit carefully using appropriate tools – never hammer directly on bearing rings.
For optimal service life, re-grease the bearing via grease fitting every 250 working hours with lithium-based EP2 grease. Check seal integrity every 500 hours, especially in dusty environments, and replace seals immediately if cracks appear.
Monitor for radial play using a dial indicator: if radial clearance exceeds 0.4 mm, replacement with OEM 800515284 is strongly recommended to prevent secondary damage to adjacent pins and bushings.
Generic spherical bearings often use softer steel or lack proper heat treatment, leading to premature spalling. The genuine XCMG component with OEM code 800515284 undergoes 100% magnetic particle inspection to guarantee zero subsurface defects.
Field tests show that original bearings withstand 35% higher impact loads than non-genuine alternatives. Moreover, the precision ground raceway reduces friction torque by 18%, improving fuel efficiency and hydraulic responsiveness.
Counterfeit products usually skip the anti-corrosion layer, causing rust within months. With XCMG’s advanced zinc-nickel coating, the 800515284 spherical bearing remains operational even in saline or high-humidity conditions.
Each batch of 800515284 spherical bearings is produced under strict TS 16949 standards. Dimensional accuracy meets ABEC-3 tolerance class. Random samples undergo accelerated life testing simulating 5000 hours of grader articulation cycles.
XCMG provides full traceability from raw material to finished component. Packaging includes individual anti-rust wrapping and certified dimensional report. Warehouses comply with dry, clean storage ensuring immediate readiness for deployment.
The spherical bearing is designed for heavy-duty graders that operate in mining, highway construction, and land leveling projects worldwide. Leading contractors trust XCMG genuine parts to minimize unplanned downtime.
Cross-reference 800515284 replaces old part numbers 800515285, 860115823, and fits XCMG motor grader series produced after 2012. Always verify your machine serial number with our compatibility table to ensure correct fitment.

Pair this bearing with XCMG-branded pins (OEM 800515285A) for maximum service life. The matched set ensures proper clearance and grease flow, elevating grader steering precision and blade control.
Q: Can I use the 800515284 bearing on other brands like Caterpillar? A: While dimensions might be similar, we recommend using only with XCMG grader linkages for guaranteed performance; however, engineering review may confirm cross-compatibility.
Q: What lubricant is recommended for extreme cold regions? A: For -40°C applications, use synthetic grease (Mobilith SHC 100) after flushing original lubricant – ensure seal compatibility.
Q: How to detect early failure of spherical bearing? A: Listen for grinding noise during circle rotation, increased steering effort, or visible radial movement over 0.3mm. Immediate replacement avoids costly structural damage.
