The genuine XCMG 800107081 Needle Roller Bushing is a precision‑manufactured rolling element bearing component designed for XCMG GR series motor graders. This OEM needle roller bushing is used in articulation pivot joints, blade lift linkages, and circle rotation mechanisms, where it provides low‑friction oscillation and high radial load capacity in a compact form factor. Manufactured from case‑hardened bearing steel (SAE 52100) with precision‑ground needle rollers retained in a steel cage, the 800107081 needle roller bushing ensures reliable performance under high shock loads and continuous oscillation.
The 800107081 bushing has a nominal inner diameter of 45 mm, outer diameter of 55 mm, and length of 40 mm (exact dimensions as per OEM drawing). The needle rollers are longitudinally guided in a drawn steel cage, and the assembly is designed to be pressed directly into a housing bore, eliminating the need for separate raceways. The bushing is pre‑lubricated with high‑performance EP grease and is equipped with sealing grooves for optional dust seals. This component is a direct replacement for worn or damaged needle roller bushings in GR135, GR165, GR180, GR215, GR260, GR300, GR350, and GR2003 graders.
A worn needle roller bushing will cause excessive play in articulation or circle rotation, leading to poor blade control and accelerated wear of adjacent components. Replacing a failed bushing with genuine XCMG 800107081 restores original clearances and reduces friction. Keep this bushing in your parts inventory for quick repair of pivot joints or linkage assemblies.

The 800107081 needle roller bushing is used in high‑load oscillating joints such as the articulation pivot between the front and rear frames. It allows the grader to articulate smoothly while supporting heavy side loads.
In the blade lift linkage, this bushing supports the pin that connects the lift arm to the blade frame. A worn bushing causes blade droop, reduced grading accuracy, and increased wear on pins and mounting brackets.
The full complement of needle rollers provides maximum load capacity for a given envelope. The caged design ensures even roller spacing and prevents skewing, which could cause edge loading and premature failure.
Replacing a worn needle roller bushing with genuine XCMG 800107081 restores tight clearances, eliminates linkage slop, and improves machine controllability. Regular greasing through the provided fitting is essential for long life.
XCMG manufactures the 800107081 bushing from vacuum‑degassed SAE 52100 bearing steel, ensuring the absence of harmful oxide inclusions that could initiate fatigue cracks under rolling contact.
The outer shell is drawn from thick‑walled tube, 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. The rollers are crowned at the ends to prevent stress concentration.
The steel cage is stamped and heat‑treated, then manganese phosphated to retain lubricant and resist corrosion. The bushing is assembled with a full complement of rollers (no spacers) for maximum load capacity.
Each bushing is 100% inspected for inner/outer diameter, radial clearance, and roller torque (resistance to rotation). Random samples are load‑tested on a tribometer to verify dynamic capacity. Genuine XCMG bushings outlast aftermarket parts by a factor of 3–5 times.
Before installing the 800107081 bushing, clean the housing bore thoroughly and inspect for burrs or scoring. The bore diameter should be checked – a slight interference fit (M7 tolerance) is required for proper retention.
Apply a thin film of anti‑seize or grease to the outer diameter of the bushing. Use a press or hydraulic tool to install the bushing, ensuring it is square to the bore. Never hammer the bushing directly, as this can dislodge rollers.
After installation, measure the inner diameter with a plug gauge. The shaft (pin) should have a running clearance of 0.02–0.06 mm. If the fit is too tight, the bushing may need honing – but genuine XCMG bushings are manufactured to the correct final dimension.
Lubricate the bushing with EP2 grease before inserting the shaft. Install dust seals if required. Keep spare 800107081 bushings in your shop for articulation joint or linkage repairs.
Aftermarket needle roller bushings often use low‑grade steel with insufficient hardness, causing rapid wear and indentation of the rollers. Many have poor roller geometry (out‑of‑round, inconsistent diameter), leading to premature spalling and seizure.
Counterfeit bushings may lack a proper cage, allowing rollers to skew and lock up under oscillation. Some have incorrect outer diameter dimensions, resulting in a loose fit and housing damage. The surface finish of the inner bore often exceeds Ra 0.2 µm, causing high friction.
XCMG provides a 12‑month warranty against manufacturing defects. Each genuine bushing is marked with the OEM number and batch code. The cost of an OEM bushing is minor compared to the downtime and housing damage caused by a failed aftermarket part. Always choose genuine for critical pivot joints.
Audible signs: clicking or knocking noise when the grader articulates or when the blade is lifted/lowered. Visual signs: visible play when the joint is pried with a bar, rust coloured grease (indicating fine metal debris), and scoring on the shaft.
Preventive replacement is recommended every 3,000 operating hours or during any major overhaul of the articulation or blade linkage. The bushing is sacrificial – it is meant to wear instead of the expensive housing or pin.
Keep a stock of 800107081 bushings in your fleet inventory. When replacing a pin, always inspect the bushing; if any radial play is detectable (more than 0.2 mm), replace the bushing. A proactive bushing replacement strategy eliminates loose joints and extends the life of mating components.
