XCMG XE2000 excavator locking nut (part number 800168962): Prevents loosening and ensures safe connection of components.

During heavy-duty operations, critical connection points of the XCMG XE2000 excavator, such as the slewing bearing, hydraulic cylinders, and transmission components, must withstand high-frequency vibration and impact. Ordinary nuts are prone to loosening, leading to component displacement, abnormal noise, or even breakage, seriously threatening operational safety. As a core fastener with anti-loosening function, the locking nut is the “last line of defense” ensuring connection reliability. This article focuses on the XCMG XE2000 original locking nut (part number 800168962) – this excavator anti-loosening locking nut, with its strong locking force and precise fit, builds a solid safety barrier for component connections.

Precisely compatible with XE2000: No deviation from original factory specifications

This locking nut (part number 800168962) is custom-made to strictly conform to the thread specifications, bore diameter, and thickness of the corresponding components for the XCMG XE2000 excavator. Its thread profile accuracy and outer diameter perfectly match the original factory mounting position. Whether fixing the slewing bearing or tightening the hydraulic cylinder piston rod, no thread grinding or installation clearance adjustment is required. It can directly and precisely mesh with the original factory bolts, and after tightening, there is no looseness against the surface of the component—avoiding connection misalignment caused by specification deviations and ensuring that every critical connection meets the original factory assembly standards. As a dedicated locking nut for the XE2000, it is a core component for maintaining the connection precision of components.

Anti-loosening structure: Will not loosen in vibrating environments

Employing a “double-nut locking” or “toothed stop surface” design (depending on original factory configuration) and utilizing a high-strength threaded locking principle, this nut provides a durable anti-loosening force after tightening. The double nuts counteract the loosening torque caused by vibration through mutual compression, while the toothed stop surface prevents relative rotation of the nuts by engaging the surfaces of the components. Even under the severe vibrations of the XE2000 operating at full load, it prevents the nuts from loosening on their own. Compared to ordinary nuts, its anti-loosening reliability is improved by more than 80%, effectively avoiding component wear and downtime caused by nut loosening. This high-reliability anti-loosening nut feature is a key guarantee for connection safety under heavy-duty conditions.

High-strength material: wear-resistant and corrosion-resistant

Made from high-quality alloy structural steel (such as 45# steel or 35CrMo) through quenching and tempering heat treatment, and surface-plated with color zinc or Dacromet coating, these nuts possess excellent wear resistance and corrosion resistance. Even under prolonged high-intensity tightening forces, the nuts show no deformation or stripping, and the thread strength meets the heavy-duty requirements of excavators. In humid and oily construction environments, the surface coating effectively blocks corrosive media, preventing the nuts from rusting and seizing, and ensuring easy disassembly for later maintenance. They maintain structural stability even after long-term use, with a service life far exceeding that of ordinary carbon steel nuts.

Key function: Ensuring safe connection of components
Anti-loosening fastening: Secure key components such as slewing bearings and hydraulic cylinders to prevent nuts from loosening due to vibration;
Load transmission: Stably transmits the forces between components, ensuring uniform stress at the connection points and reducing localized wear;
Safety protection: To prevent component failures caused by loose nuts, ensuring the safety of excavator operation and operators.

As a high-strength fastener for construction machinery, the XCMG XE2000 excavator locking nut (part number 800168962) is an essential accessory for maintaining the original factory connection standard and ensuring the efficient and safe operation of the excavator. Choosing the original factory locking nut means choosing connection safety and long-term operational stability.
