The genuine XCMG 860517093 Ball Bearing is a high‑precision deep‑groove ball bearing engineered for XCMG GR series motor graders. This OEM bearing is used in wheel hubs, final drive pinion supports, differential side shafts, and fan drive idler pulleys, where it carries radial and axial loads with minimal friction. Manufactured from vacuum‑degassed chrome steel (SAE 52100) with precision‑ground raceways and grade 10 balls, the 860517093 ball bearing delivers excellent fatigue life and dimensional stability under extreme shock loads, vibration, and temperature fluctuations typical of heavy grading applications.
The 860517093 bearing is a single‑row deep‑groove type with dimensions: 45 mm bore, 85 mm outer diameter, and 19 mm width. It features a C3 radial internal clearance for high‑temperature operation and a double rubber seal (2RS) that retains lubricant and excludes dirt. The cage is made from pressed steel, and the bearing is pre‑filled with high‑quality lithium EP2 grease. This component is a direct replacement for original bearings on GR135, GR165, GR180, GR215, GR260, GR300, GR350, and GR2003 motor graders.
A worn or spalled ball bearing will produce noise, vibration, and increased rolling resistance, leading to wheel wobble, transmission whine, or pulley seizure. Replacing a failed bearing with genuine XCMG 860517093 restores smooth rotation, reduces friction, and protects adjacent components from overheating. Keep this bearing in your parts inventory for axle, differential, or auxiliary drive repairs.

The 860517093 ball bearing is installed in the wheel hub of XCMG motor graders, supporting the entire weight of the machine while allowing the wheel to rotate freely. It simultaneously handles radial loads (from machine weight) and axial loads (from cornering and side grading forces).
In the final drive, this bearing supports the pinion shaft, maintaining precise gear mesh between the pinion and crown wheel. A worn bearing here can cause excessive runout, leading to gear tooth breakage and expensive differential repairs.
The deep‑groove design enables the bearing to accommodate both radial and thrust loads, making it ideal for high‑speed rotation up to 6,000 rpm. The C3 clearance allows for thermal expansion without internal preload, preventing overheating and smearing.
Replacing a noisy or rough‑turning bearing with genuine XCMG 860517093 restores smooth wheel rotation, reduces fuel consumption, and eliminates vibration in the cab, improving operator comfort and machine control.
XCMG specifies vacuum‑degassed SAE 52100 chrome steel for the 860517093 bearing to eliminate non‑metallic inclusions that initiate fatigue cracks. The steel is spheroidize annealed, then machined into rings and balls with sub‑micron tolerances.
The raceways are ground and superfinished to Ra 0.05 μm, and the balls are lapped to grade 10 sphericity. The bearing is heat‑treated (austenitized, oil quenched, tempered) to achieve a uniform hardness of 60–64 HRC with a martensitic microstructure.
The pressed steel cage is riveted and treated with manganese phosphate for lubricity. The 2RS nitrile rubber seals are moulded onto a steel insert, providing IP55 dust protection. Each bearing is noise‑tested on an Anderometer and 100% inspected for radial runout and clearance.
Random samples are subjected to accelerated life testing (500 hours at maximum load and speed). Genuine XCMG bearings consistently achieve a calculated L10 life exceeding 10,000 hours under normal grading conditions, far surpassing aftermarket alternatives.
Before installing a new 860517093 bearing, inspect the shaft and housing for burrs, nicks, or out‑of‑round condition. The shaft should have a surface finish of Ra 0.4–0.8 μm and a hardness of at least 55 HRC. The housing bore should be within ISO H7 tolerance.
Apply a thin film of clean oil to the bearing outer ring and inner bore. Use an induction heater to warm the bearing to 80–100°C for easier installation onto the shaft. Apply force only to the ring being press‑fitted – never hammer on the outer ring when mounting on a shaft.
After installation, rotate the shaft by hand to check for smooth operation. There should be no notching or binding. Install the retaining ring or locknut to the torque specified in the service manual. For wheel hub applications, adjust the bearing end‑play to 0.05–0.15 mm.
Keep spare 860517093 bearings in your parts store for emergency repairs. Never use a bearing that has been dropped or shows any sign of contamination – a single particle can cause rapid failure. Use proper tools to avoid damaging the seals or raceways.
Aftermarket ball bearings often use lower‑grade steel (e.g., 100Cr6 without vacuum degassing) leading to premature spalling and fatigue failure within 1,500 hours. Many have inaccurate raceway geometry, causing high noise and vibration from the start.
Counterfeit bearings may have poorly bonded seals that allow dirt ingress, destroying the bearing in weeks. Some have incorrect C3 clearance (often too tight), resulting in thermal seizure at high speed. Genuine XCMG bearings are 100% verified for clearance, noise, and seal integrity.
The cost of a genuine bearing is a fraction of the labour and damage caused by a failed aftermarket bearing. XCMG provides a 12‑month warranty against manufacturing defects. Each genuine bearing is laser‑etched with the 860517093 number and XCMG logo, and packed in a sealed anti‑corrosion sleeve. Always choose OEM for critical rotating assemblies.
Audible indicators: deep rumbling or growling noise that increases with wheel speed, or a high‑pitched squeal (from lack of grease). Vibration measured on the axle housing exceeding 3 mm/s RMS. Visual signs include rough rotation, rust spots on the exposed inner ring, and grease leakage with metallic flakes.
Preventive replacement is recommended every 4,000 operating hours for wheel hub bearings and every 5,000 hours for final drive bearings under normal use. For graders working in abrasive environments (sand, crushed stone), reduce intervals by 30%. During each 1,000‑hour service, use a stethoscope to listen for bearing noise and check bearing temperature with an infrared thermometer – any hotspot over ambient+70°C warrants inspection.
Keep a stock of 860517093 bearings in your fleet warehouse. When overhauling a wheel hub or differential, always replace all bearings – reusing old bearings is a false economy. A proactive replacement strategy eliminates unscheduled downtime and protects expensive gear sets and housings.
