800167068 semi-circle key XCMG XE2000 excavator spare parts

XCMG XE2000 excavator semi-circular key 800167068 | Original factory fit, precise transmission, wear-resistant and damage-resistant, ensuring stable shaft connection.

In the transmission system of the XCMG XE2000 excavator, the synchronous rotation of the shaft and hub (such as gears and couplings) relies on the precise positioning and torque transmission of the semi-circular key. The XCMG XE2000 original semi-circular key (part number 800167068), as a core transmission connector, can tightly embed into the keyway of the shaft and hub, preventing transmission slippage and torque loss caused by key wear and deformation. This provides a solid “transmission bridge” for the stable operation of key shaft systems such as the XE2000 excavator’s hydraulic pump and slewing mechanism.

800167068 Semi-circular Key: Three Core Advantages, Compatible with XE2000

Original factory precise fit: The dimensions strictly follow the XCMG XE2000 shaft system design standard. The key width, key height, and radius of curvature are perfectly matched with the keyway of the shaft and hub (dimensional tolerance ≤0.01mm). It can be directly assembled without grinding, avoiding loose keyway fit and abnormal transmission noise caused by fit deviation. It ensures synchronous rotation of the shaft and hub and is compatible with torque transmission requirements in multiple scenarios such as hydraulic transmission and mechanical transmission.
High strength, torsional resistance and wear resistance: Made of high-quality carbon structural steel (45# steel), it undergoes overall quenching and low-temperature tempering treatment, achieving a surface hardness of HRC50-55 and a tensile strength ≥600MPa. It can withstand the high-frequency torque impact and shear force during excavator operation. The key surface is precision ground (surface roughness Ra≤0.4μm) to reduce frictional loss with the keyway and effectively prevent increased transmission clearance and decreased torque transmission efficiency due to wear.
Corrosion resistant, durable and long service life: The surface is treated with blackening and rust prevention, and has passed the salt spray test for more than 200 hours. It can resist the corrosion of lubricating oil impurities and slight moisture in the transmission system, and avoid disassembly difficulties and keyway jamming caused by key body corrosion. It maintains structural stability in a temperature range of -30℃ to 120℃, with no risk of brittleness or deformation, and has a service life of more than 8,000 hours (60% longer than ordinary low carbon steel semi-circular keys), reducing shaft system maintenance and downtime costs caused by key body failure.

Suitable for multiple scenarios, with traceable quality, and safe to use.

Whether the XE2000 is operating in hard rock mining (high torque conditions), construction earthmoving (frequent start-stop), or in humid and dusty outdoor environments, the 800167068 semi-circular key consistently performs its transmission and positioning functions reliably. Each semi-circular key undergoes triple testing by XCMG (dimensional accuracy calibration, hardness testing, and torsional strength testing), conforming to the GB/T 1099 semi-circular key standard and engineering machinery transmission component specifications. Official traceability is supported, ensuring safe and trouble-free use and preventing shaft damage and transmission failure caused by the breakage of inferior semi-circular keys.

Select 800167068, protect the XE2000 shaft drive.

If you are experiencing issues with the XCMG XE2000 transmission system, such as slippage, misalignment between the shaft and wheel hub, or the need to replace worn or aged semi-circular keys, the original 800167068 semi-circular key is the optimal choice. It ensures stable shaft transmission with precise fit and reliable torsional resistance, reducing the risk of transmission failures and enabling the XE2000 to continuously output power under various high-intensity working conditions, thus facilitating efficient engineering operations.
