The 800515282 Spherical Bearing SI10E is a genuine OEM rod end bearing manufactured by XCMG for motor graders and heavy construction equipment. This maintenance‑free spherical bearing provides articulation and misalignment compensation in critical linkage systems, including blade lift linkages, ripper connections, and steering components.
Engineered from high‑strength steel with a hard chrome‑plated spherical ball and a PTFE‑lined inner race, the 800515282 bearing withstands extreme loads, shock, vibration, and contamination. It directly replaces worn, seized, or corroded spherical bearings on XCMG GR series graders and compatible machinery.
Each unit features an M10×1.5 male thread, a 10 mm bore, and a 35 mm housing width. The bearing is pre‑lubricated with a high‑performance grease and sealed with double lip seals to retain lubricant and exclude dirt. This ensures long service life in dusty, muddy, and wet working conditions.

The XCMG 800515282 Spherical Bearing SI10E is a key component in motor grader articulation joints. It allows smooth rotational movement while accommodating angular misalignment between connected parts. In blade lift linkages, the bearing connects hydraulic cylinder rods to the moldboard frame, absorbing side loads and preventing binding.
The PTFE‑lined inner race provides a low‑friction interface that requires no external lubrication. This is essential for hard‑to‑reach joints on the undercarriage or behind the cab. The double lip seals keep contaminants out even during pressure washing or deep mud operation.
Worn spherical bearings cause play in the linkage, leading to erratic blade movement, uneven grading, and accelerated wear of pins and bushings. Replacing a seized or loose bearing with the 800515282 restores precise control and extends the life of the entire hydraulic system.
The spherical ball is made from 100Cr6 bearing steel, through‑hardened to HRC 58‑62, then ground to a mirror finish (Ra ≤ 0.1 µm). This ensures smooth rotation and high wear resistance. The housing is forged from C45 carbon steel, then machined to precise dimensions. The M10 thread is rolled (not cut) for maximum fatigue strength.
The PTFE fabric lining is woven from high‑tenacity fibers and impregnated with a proprietary resin. It provides a coefficient of friction as low as 0.05 under static loads and 0.15 under dynamic loads. The lining is bonded to the inner race using a high‑temperature adhesive, ensuring it does not delaminate under shock loads.
XCMG tests each bearing for radial play, axial clearance, and torque resistance. The zinc plating meets ASTM B117 for 500 hours of salt spray without red rust. This makes the 800515282 suitable for coastal and winter road maintenance environments.
To replace a worn spherical bearing, first relieve hydraulic pressure and support the linkage. Remove the retaining nut or circlip that secures the bearing. Use a suitable puller to extract the old bearing from the housing. Clean the bore with a wire brush and solvent. Apply a thin layer of anti‑seize to the bearing housing.
Install the new 800515282 bearing using a press or a threaded rod tool. Never hammer the bearing directly, as this can damage the PTFE lining. Torque the retaining nut to the value specified in the service manual (typically 30 Nm for M10 threads). After installation, check for smooth articulation and absence of excessive play.
If the bearing is mounted on a clevis, ensure that the spherical ball aligns with the mating pin. The bearing should rotate freely through its ±15° tilt range. If binding occurs, check for misalignment or a bent housing.
Aftermarket spherical bearings often use low‑grade steel balls that pit and corrode quickly, or PTFE linings that wear out within months. The genuine XCMG bearing is manufactured to original equipment tolerances and material specifications. It provides consistent performance and long service life.
Counterfeit bearings may have incorrect thread pitch or diameter, causing cross‑threading and premature failure. The 800515282 matches the exact OEM dimensions. Additionally, genuine bearings include double lip seals; many aftermarket units omit the seals to cut costs, allowing dirt ingress.
XCMG provides a 12‑month warranty against manufacturing defects. Each bearing is laser‑etched with the XCMG logo and part number. This supersedes older numbers 800515200 and 800515245, with improved corrosion resistance and a more durable PTFE lining.
Common symptoms of a failing spherical bearing: excessive radial play (the ball can be moved side‑to‑side), a notchy or gritty feel when rotating, visible rust on the ball, or torn seals. Also, if the linkage makes clunking noises during operation, the bearing likely has significant wear.
Preventive replacement every 4,000 operating hours is recommended for bearings in high‑load applications (blade lift, ripper). The cost of a genuine bearing is minimal compared to the cost of repairing a damaged cylinder rod or frame lug caused by excessive play.
During routine maintenance, inspect the seals for cracks and the ball for pitting. Apply a small amount of grease to the outside of the seals to keep them pliable. Never use a pressure washer directly on the bearing, as high pressure can force water past the seals.
