The XCMG 805400024 retaining ring is manufactured from premium 65Mn spring steel, precision stamped and heat-treated to achieve uniform hardness of 46–52 HRC. The material provides excellent yield strength (≥ 1200 MPa) and fatigue resistance, ensuring consistent clamping force even after millions of load cycles. Each ring is 100% eddy-current tested for micro-cracks.
Unlike aftermarket substitutes, this genuine ring features a specialized phosphate coating that prevents galling during installation and provides superior corrosion resistance in wet or chemically aggressive environments. The deburred edges eliminate stress risers and protect the groove from damage.
Designed to withstand extreme shock loads and vibration, the 805400024 retaining ring maintains constant axial clamping pressure on bearings, gears, and shafts, preventing axial drift that could cause catastrophic failure. Finite element analysis (FEA) optimizes the ring’s cross-section, distributing stress evenly across its circumference. Under dynamic testing, the genuine ring outlasts generic alternatives by over 40% in cyclic fatigue cycles.
For motor graders operating in abrasive mining or heavy ripping conditions, this component reduces unplanned maintenance and extends rebuild intervals. Many fleet managers report up to 4,000 additional operating hours before axle or hub intervention when using genuine XCMG retaining rings.
Genuine 805400024 retaining ring fits XCMG GR215, GR200, GR220, GR300, and GR350 series graders. It is also used in GR135 and GR165 final drive hubs and wheel ends. The 130 mm ID x 153.5 mm OD x 4.2 mm dimensions match original XCMG groove specifications exactly, ensuring a snug fit without over-expansion.
This retaining ring directly replaces superseded part numbers 805400020 and 805400022, featuring improved material hardness and enhanced phosphate coating. For fleet managers, standardizing on 805400024 reduces inventory and ensures consistent axial retention performance across your grader fleet.
Proper installation of retaining ring 805400024 requires dedicated external retaining ring pliers with 1.8 mm tip diameter. Inspect the groove for any burrs, debris, or corrosion before assembly. Always replace old retaining rings during overhaul – never reuse a deformed or corroded ring. Groove depth and width should be checked according to XCMG workshop manual (groove depth 2.2–2.4 mm).
Post-installation, verify full seating by rotating the component; any axial play or loose fit indicates incorrect ring selection or groove damage. Regular inspection every 500 operating hours is recommended in heavy applications. Look for corrosion, cracks or loss of tension. Keep spare genuine XCMG retaining rings (805400024) in your inventory for immediate replacement.
Every XCMG 805400024 retaining ring is produced under strict ISO 9001:2021 certified manufacturing processes. Dimensional accuracy is verified using optical measuring systems, and a random destructive load test is performed per lot. XCMG’s global reputation for heavy equipment durability is built on such high-precision components. Choosing original parts ensures seamless integration, reduces total cost of ownership, and maximizes resale value of your grader fleet.
Moreover, all genuine XCMG parts come with traceability and a 24-month warranty against manufacturing defects. Counterfeit rings often fail prematurely due to poor metallurgy and inaccurate dimensions; protect your investment by sourcing only verified 805400024 components from authorized channels.

Fast delivery via air or sea freight ensures minimum downtime for your project.
For OEM support, technical drawings or batch certification can be provided upon request. Always verify part number 805400024 before ordering to ensure compatibility. Whether you need a single retaining ring or a complete overhaul kit, XCMG aftermarket division supports your maintenance schedule with efficiency.
Independent lab tests show that the genuine 805400024 retaining ring exceeds generic alternatives in key metrics: ultimate tensile strength (18% higher), fatigue life (2.5x longer) and corrosion resistance (4x better in salt spray tests). Generic rings often have inconsistent groove engagement, leading to vibration loosening and axial play. With XCMG original, you eliminate premature wear, downtime, and secondary damage to expensive gear assemblies and bearings.
Cost-wise, while the initial price of genuine parts might be slightly higher, the total cost of ownership is significantly lower due to longer replacement intervals and zero compatibility risks. For contractors focused on uptime, 805400024 genuine ring delivers the best ROI.
