The genuine XCMG 800107082 Needle Roller Bushing is a precision‑engineered rolling element bearing component designed for XCMG GR series motor graders. This OEM needle roller bushing is used in high‑load oscillating applications such as articulation pivot joints, blade lift linkages, circle rotation supports, and idler pulley shafts. Manufactured from case‑carburized bearing steel (SAE 52100) with precision‑ground needle rollers retained in a drawn steel cage, the 800107082 needle roller bushing provides low‑friction, high‑radial capacity in a compact form factor, essential for the demanding conditions of road grading, snow removal, and heavy earthmoving.
The 800107082 bushing has a nominal inner diameter of 50 mm, an outer diameter of 60 mm, and a length of 45 mm (exact as per XCMG drawing). The full‑complement needle roller design (or caged version) maximizes load‑carrying capacity within a limited envelope. The rollers are crowned to avoid edge loading, and the outer race is induction‑hardened to 60–64 HRC for exceptional wear resistance. The bushing is pre‑lubricated with high‑performance EP2 grease and features grease grooves for re‑lubrication. This component directly replaces worn or damaged bushings in GR135, GR165, GR180, GR215, GR260, GR300, GR350, and GR2003 graders.
A worn needle roller bushing results in excessive play in the articulation joint or blade linkage, causing loss of control, increased vibration, and accelerated wear of mating pins and housings. Replacing a failed bushing with genuine XCMG 800107082 restores original clearances, reduces friction, and ensures smooth, predictable machine handling. Keep this bushing in your parts inventory for rapid repair of pivot points and linkage assemblies.

The 800107082 needle roller bushing is the heart of the grader’s articulation and blade pivot systems. It allows the front frame to articulate relative to the rear frame, enabling tight turning radii and precise blade positioning.
In the blade lift linkage, this bushing supports the pin that connects the lift arm to the blade frame. A worn bushing causes the blade to droop, reducing grading accuracy and accelerating wear on hydraulic seals.
The full complement of needle rollers provides maximum load‑carrying capacity for a given size, minimizing the bushing footprint while supporting heavy side loads from blade impacts.
Replacing a worn bushing with genuine XCMG 800107082 restores tight clearances, eliminates play, and improves machine control. Regular greasing through the provided fitting is essential for long life.
XCMG selects vacuum‑degassed SAE 52100 chrome steel to ensure the complete absence of oxide inclusions that could initiate fatigue cracks under rolling contact stress.
The outer shell is drawn from high‑density tube stock, then case‑carburized and hardened to 60–64 HRC. The needle rollers are cold‑headed, ground, and lapped to a surface finish Ra ≤0.05 µm.
Roller ends are crowned to prevent edge loading, which significantly increases fatigue life under oscillating motion. The steel cage is stamped, heat‑treated, and manganese phosphated for lubricant retention.
Each bushing is 100% inspected for inner/outer diameter, radial clearance, and roller torque. Random samples are tested on a tribometer under simulated articulation cycles. Genuine XCMG bushings outlast aftermarket parts by a factor of 3–5 times.
Before installing the 800107082 bushing, clean the housing bore with a solvent and inspect for burrs or scoring. The bore diameter should be within M7 tolerance for a proper interference fit.
Apply a thin film of anti‑seize grease to the outer diameter of the bushing. Using a hydraulic press or a sleeve, drive the bushing squarely into the bore until it seats against the shoulder. Never hammer directly on the bushing.
After installation, use a plug gauge to verify the inner diameter. The mating pin should have a running clearance of 0.02–0.06 mm. If the fit is too tight, the bushing may require light honing – but genuine XCMG bushings are supplied at final dimension.
Lubricate the bushing with EP2 grease before inserting the pin. Install dust seals if required. Keep spare 800107082 bushings in your shop for articulation joint and linkage overhauls.
Aftermarket needle roller bushings frequently use low‑grade steel with insufficient hardness, causing rapid indentation of the raceway and roller flattening within months of service.
Many counterfeit bushings have inconsistent roller diameters, leading to uneven load distribution, spalling, and eventual seizure in the pivot joint. Some lack proper caging, allowing rollers to skew and lock up.
The outer diameter of aftermarket bushings is often oversized or undersized, causing either a loose fit (housing damage) or an interference fit that cracks the housing. Genuine XCMG bushings are precision‑ground to exact DIN/ISO tolerances.
XCMG provides a 12‑month warranty against manufacturing defects. Each genuine bushing is laser‑etched with the OEM number and batch code. Using OEM bushings prevents sloppy articulation, reduces maintenance costs, and extends the life of expensive pins and housings.
Audible indicators: knocking or clunking when articulating the grader or raising/lowering the blade. Visual signs: a visible gap between the pin and bushing (more than 0.5 mm radial play), rust‑coloured grease indicating fine metal debris, or scoring on the pin.
Preventive replacement is recommended every 3,000 operating hours or during any major overhaul of the articulation joint or blade linkage. The bushing is a sacrificial component – it is designed to wear instead of the housing or pin.
If radial play can be felt by hand when prying the joint, the bushing has exceeded its service limit. Waiting too long will result in an oval‑shaped housing, requiring expensive re‑boring or replacement.
Keep a stock of 800107082 bushings in your fleet inventory. When replacing a pin, always inspect the bushing and replace it if any play is detected. Proactive bushing replacement eliminates loose joints and extends the life of the entire pivot assembly.
