The 800513992 Spherical Bearing GE40ES is a genuine OEM precision component manufactured by XCMG for motor graders and heavy construction equipment. This steel‑on‑steel spherical plain bearing provides reliable articulation and misalignment compensation in critical linkage systems, including blade lift linkages, ripper connections, circle rotation mechanisms, and steering components. Designed to accommodate high radial and axial loads while allowing angular misalignment, the GE40ES bearing ensures smooth, low‑friction movement under extreme operating conditions. Each unit is manufactured to ISO 12240‑1 standards, with a hardened and ground steel inner ring, a similarly hardened outer ring, and a phosphate‑coated surface for corrosion resistance.
The 800513992 bearing directly replaces worn, seized, or corroded spherical bearings on XCMG GR135, GR165, GR180, GR215, GR260, GR300, and GR350 motor graders. Its maintenance‑free design (with initial lubrication) provides long service life in dusty, muddy, and high‑vibration environments. The GE40ES designation indicates a 40 mm bore diameter, making it suitable for heavy‑duty pinned joints throughout the grader’s undercarriage and implement systems.
Proper functioning of spherical bearings is critical for maintaining precise blade control, smooth articulation, and extended component life. A worn or seized bearing can cause erratic movement, accelerated wear of pins and bushings, and reduced grading accuracy. Replacing a damaged bearing with the genuine XCMG 800513992 restores proper joint articulation and eliminates play.

The XCMG 800513992 Spherical Bearing GE40ES is a fundamental component in the motor grader’s mechanical linkage systems. Unlike standard roller bearings, spherical plain bearings allow angular misalignment between the shaft and housing while supporting high radial and axial loads. This capability is essential for joints that must accommodate manufacturing tolerances, deflection under load, and dynamic movement during machine operation.
Typical applications on XCMG GR graders include the blade lift linkage pivot points, circle rotation mechanism, rear ripper attachment joints, and steering cylinder mounts. In these locations, the bearing must absorb shock loads, allow free rotation, and resist corrosion from dirt and moisture. The GE40ES steel‑on‑steel design provides excellent load capacity and wear resistance, making it ideal for heavy‑duty construction environments.
The bearing’s inner and outer rings are made from hardened bearing steel (100Cr6) with a sliding contact surface that is phosphate‑coated for initial corrosion protection and lubricated with high‑performance grease. Under normal operating conditions, the bearing is maintenance‑free; however, in extreme applications (continuous water immersion or abrasive dust), periodic relubrication can extend service life.
A worn spherical bearing manifests as excessive radial play, a notchy or gritty feel when rotating, visible rust on the ball, or torn seals. If not replaced, it can cause accelerated wear of the mating pin and housing bore, leading to expensive repairs. Replacing a failed bearing with the genuine 800513992 restores proper joint function and eliminates play.
Each 800513992 spherical bearing is manufactured in an ISO 9001:2015‑certified facility using high‑grade 100Cr6 bearing steel. The inner and outer rings are forged, then heat‑treated to achieve a hardness of HRC 58‑62. The spherical surfaces are precision ground to a surface finish of Ra ≤ 0.2 µm, ensuring low friction and consistent torque. The rings are then matched for radial clearance (typically C0 or C3) and assembled with a phosphate coating to prevent galling during initial operation.
After assembly, each bearing is tested for radial internal clearance, axial displacement, and rotational torque. Random samples from each batch undergo a 500‑hour salt spray test (ASTM B117) to verify corrosion resistance. The bearing is also subjected to a static load test at 1.5 times the rated dynamic load to confirm structural integrity.
The final product is lubricated with a lithium‑based grease containing EP additives and corrosion inhibitors. The bearing is then sealed in anti‑rust paper and individually boxed to prevent contamination during storage and transport.
Replacing a worn spherical bearing requires proper tools and care. First, relieve any load on the joint and remove the retaining pin or bolt. Use a suitable puller or press to extract the old bearing from the housing. Never hammer the bearing directly, as this can damage the housing or the new bearing. Clean the housing bore with a wire brush and solvent, then inspect for burrs or deformation.
Apply a thin layer of anti‑seize or grease to the outside of the new 800513992 bearing to ease installation. Press the bearing into the housing using a press or a threaded rod tool, applying force only to the outer ring. Do not press on the inner ring, as this can distort the bearing. After installation, apply grease to the bore of the inner ring and insert the pin. Torque the retaining nut to the specification in the service manual (typically 150‑200 Nm for M20 pins).
After assembly, check for smooth articulation and absence of excessive play. If the joint feels rough or binds, disassemble and inspect for misalignment or debris. Always replace the pin if it shows signs of wear or corrosion. For best results, replace all bearings in a linkage as a set to ensure even wear and consistent performance.
Aftermarket spherical bearings often use lower‑grade steel or lack proper heat treatment, leading to rapid wear and premature failure. The genuine XCMG 800513992 is manufactured to the exact specifications of the original equipment, ensuring correct internal clearances, load capacity, and fatigue life. Aftermarket bearings may also have incorrect outer diameter tolerances, causing a loose fit in the housing or difficulty during installation.
Counterfeit bearings often omit the phosphate coating or use a simple zinc plating that wears off quickly, exposing the steel to corrosion. The 800513992 features a robust phosphate coating that provides sacrificial protection and retains lubrication. Additionally, genuine XCMG bearings are batch‑tested for hardness, clearance, and load capacity, whereas counterfeit products rarely undergo any quality control.
XCMG provides a 12‑month warranty against manufacturing defects. Each bearing is stamped with the XCMG logo or comes in branded packaging. Using genuine XCMG bearings ensures compatibility, reliability, and the protection of your valuable equipment. The cost of a genuine bearing is negligible compared to the cost of a failed linkage, bent pin, or unplanned downtime.
Common signs of a failing spherical bearing include: excessive radial play (the inner ring can be moved side‑to‑side within the outer ring), a notchy or gritty feel when rotating, visible rust or pitting on the spherical surfaces, and loss of lubrication (dry, noisy operation). Also, if the linkage exhibits clunking sounds during operation or if the blade drifts unexpectedly, a worn bearing may be the cause.
Preventive replacement is recommended every 4,000 to 6,000 operating hours for bearings in high‑load applications (blade lift, circle rotation, ripper). The cost of a genuine bearing is minimal compared to the cost of a damaged cylinder rod, bent frame lug, or loss of grading accuracy. When replacing a bearing, always inspect the pin and housing bore for wear; replace or recondition as necessary.
During routine maintenance, inspect the bearing for external rust, check for play by prying the joint with a bar, and listen for noise during operation. If the bearing is accessible, apply a small amount of grease to the outside of the inner ring to keep the contact surfaces lubricated. Keep a stock of 800513992 bearings in your parts inventory for rapid field repairs. A well‑maintained spherical bearing system ensures smooth, precise machine control and extends the life of the entire linkage.
