The 860117626 Ball Bearing (type 6206) is a genuine XCMG deep groove radial ball bearing, dimensionally interchangeable with industry standard 6206. It is used in motor grader engine cooling fans, alternator drives, gearbox idler shafts, and various pivot points on XCMG GR135 through GR350 models.
This single‑row, non‑filling slot bearing features pressed steel cages, high‑grade chrome steel rings and balls, and is greased for life with a high‑temperature lithium complex grease. The 860117626 provides smooth, low‑friction rotation under radial and moderate axial loads.
A failed bearing can cause overheating, noise, vibration, and eventual seizure of the fan, alternator, or shaft, leading to engine or electrical damage. Replacing a worn bearing with the genuine XCMG 860117626 restores original rotational accuracy and extends component life.
The 860117626 conforms to ISO 15:1998 and ABEC‑1 precision class. It has a 30 mm bore, 62 mm outer diameter, and 16 mm width. The bearing is double sealed with rubber (2RS) to retain grease and exclude contaminants, making it ideal for the dusty, wet conditions typical of grader engine compartments.
Using genuine XCMG ensures correct internal clearance (C3), proper cage material, and genuine grease fill – all critical for long service life in high‑vibration applications.
Common applications include the fan hub bearing on the engine cooling system, the alternator pulley support, the water pump idler pulley, and light‑duty pivot shafts in the circle drive mechanism.
Order the XCMG 860117626 to ensure quiet, reliable operation of your grader’s auxiliary drives and rotating assemblies.

The XCMG 860117626 Ball Bearing 6206 is widely used in the grader’s engine cooling fan hub, where it supports the fan shaft at high rotational speeds.
A failed fan bearing can cause the fan to wobble, leading to radiator damage, overheating, and sudden fan blade failure.
This bearing also supports the alternator rotor; a rough or seized alternator bearing can cause charging failures, belt squeal, or complete alternator destruction.
In the gearbox and circle drive, 6206 bearings may be used on idler shafts that run at moderate speeds but under constant vibration.
The double rubber seals (2RS) are essential for keeping out dust, water, and sand while retaining the factory grease.
The C3 internal clearance allows for thermal expansion and accommodates shaft misalignment common in engine belt‑driven accessories.
Replacing a noisy or rough‑rotating bearing with genuine 860117626 restores smooth operation and prevents secondary damage to housings and shafts.
Each 860117626 bearing is manufactured from vacuum‑degassed chrome steel (GCr15) with a hardness of 60‑64 HRC on rings and balls.
The raceways are super‑finished to Ra 0.1 µm for minimal friction and noise, then assembled using high‑precision ball sorting.
The pressed steel cages are riveted for strength, and the rubber seals are molded with a steel insert for a tight fit in the outer ring groove.
XCMG’s quality control includes 100% noise (Anderon) testing, bore and OD measurement with air gauges, and radial runout checks.
Sample bearings are tested for dynamic load capacity and fatigue life per ISO 281 standards.
Genuine XCMG bearings are laser‑marked with the brand, part number 860117626, and country of origin for traceability.
Counterfeit 6206 bearings often use low‑grade steel, lack heat treatment, and have undersized balls, leading to rapid failure.
Only genuine XCMG guarantees the correct C3 clearance, seal material, and grease fill for grader applications.
Before installation, inspect the housing bore and shaft for nicks, burrs, or wear. Clean both surfaces with a lint‑free cloth.
Apply a thin film of clean oil to the shaft to ease installation. Use a bearing press or appropriate driver tool – never hammer directly on the bearing rings.
Press the bearing onto the shaft by applying force only to the inner ring; press into the housing by applying force only to the outer ring.
Do not remove the rubber seals; the bearing is pre‑greased for life. Do not wash or degrease the bearing before installation.
The bearing should rotate freely by hand with no roughness or binding after installation.
XCMG recommends replacing the 860117626 bearing whenever the fan hub or alternator is removed for service, or every 4,000 hours.
Always replace bearings in sets if multiple are used on the same shaft (e.g., two fan bearings).
Never reuse a bearing that has been removed – the rolling elements and raceways may have been damaged during extraction.
Aftermarket 6206 bearings often come from unknown sources with inferior steel that spalls after a few hundred hours of operation.
Many generic bearings have inadequate internal clearance (CN instead of C3), causing premature overheating when the shaft expands.
Aftermarket seals are often made of low‑grade rubber that hardens or cracks, allowing dirt ingress and grease leakage.
The genuine XCMG 860117626 is manufactured under strict process controls, with C3 clearance verified, seals tested for dust exclusion, and grease fill measured by weight.
Using genuine bearings also ensures that the shaft and housing are not damaged by poor fitting dimensions.
XCMG provides a 12‑month warranty against material defects and premature failure under normal operating conditions.
For fleet maintenance, genuine bearings reduce unplanned breakdowns and extend the service intervals of fan drives and alternators.
Invest in genuine XCMG for peace of mind and lower total cost of ownership.
Common signs that the 860117626 bearing needs replacement include: rough or grinding feeling when rotating the shaft, unusual whining or rumbling noise, and excessive play (radial or axial).
On the fan hub, a failing bearing may cause vibration that is felt through the radiator grill or heard as a low‑frequency growl.
For alternator bearings, increased electrical noise, intermittent charging, or a seized pulley are indicators.
Preventive replacement is recommended every 4,000 operating hours or during any major engine service (fan belt replacement, alternator overhaul).
The cost of a genuine 860117626 is negligible compared to the cost of a radiator damaged by a wobbly fan or an alternator destroyed by bearing seizure.
Keep a few of these bearings in your parts locker – they are common to many accessory drives.
When replacing a bearing, also inspect the mating shaft for wear and replace any worn seals or gaskets in the housing.
