The genuine OEM 381600397 Bronze Bushing is a precision-engineered wear component designed specifically for XCMG motor grader articulation joints. This high-strength bushing provides low-friction rotation and absorbs radial loads, ensuring smooth pivot operation and extended service life in GR series graders.
Manufactured to original equipment specifications, the 381600397 bronze bushing is centrifugally cast from high-leaded tin bronze (CuSn8Pb4 or equivalent). It features an optimized lubrication groove pattern for grease retention, withstanding static loads up to 150 MPa and operating reliably from -40°C to +150°C.
Using genuine XCMG 381600397 bronze bushings eliminates premature wear, pivot slop, and costly downtime. Each bushing undergoes 100% dimensional inspection and material hardness verification before packaging. Upgrade your grader’s articulation reliability with authentic OEM quality.
The 381600397 bronze bushing is centrifugally cast, which produces a dense, uniform microstructure with no porosity or inclusions. This process ensures consistent wear resistance and load-carrying capacity throughout the bushing wall.
The high-leaded tin bronze alloy (SAE 660) contains 6-8% lead, which acts as a solid lubricant. This reduces friction and prevents galling even under boundary lubrication conditions, common during cold starts or low-speed articulation.
Precision-machined inner and outer diameters (tolerance H8/f7) ensure a proper interference fit with the housing and a controlled clearance with the pivot pin. The optimized grease groove pattern distributes lubricant evenly across the bearing surface, minimizing localized wear.
This bronze bushing directly replaces OEM part 381600397 on XCMG GR2153, GR200, GR180, GR3005, and GR3505 graders. It is used in the front-rear articulation pivot, circle support pivot, and blade lift arm pivots.
For older GR135 and GR165 series, the 381600397 bushing offers drop-in compatibility with original bores. Cross-reference with aftermarket numbers: BB-2410, XCMG-BB210. Standardizing on genuine bushings eliminates slop and reduces steering wander.
The bushing is also used in rear axle oscillation pivots and moldboard side-shift mechanisms. Always replace the bushing and pin together for optimum service life.
Before installing the 381600397 bronze bushing, inspect the housing bore for burrs or scoring. Clean both bushing and bore with solvent. Apply a thin film of anti-seize compound on the outer diameter. Press the bushing into the housing using an arbor press (not a hammer). The force required should be steady – do not exceed 50 kN.
After installation, align the grease grooves with the housing’s lubrication hole. Ream the inner diameter to final size if necessary (max removal 0.05 mm). Lubricate the pin and bushing with clean grease before assembly. Check articulation movement – it should be smooth without binding.
All 381600397 bronze bushings are manufactured in XCMG’s ISO 9001:2015 and IATF 16949 certified facilities. Each batch undergoes 100% dimensional inspection, hardness testing, and chemical analysis (spectrometry) to verify alloy composition.
Random samples are tested for tensile strength, yield strength, and elongation per ASTM E8. Wear resistance is validated using a block-on-ring test (100 hours, 50 MPa load). XCMG provides a material certificate with each batch and a 12-month warranty against manufacturing defects.
Aftermarket bushings often use inferior bronze alloys (low lead content or sand-cast porosity), leading to rapid wear and pivot slop. Genuine 381600397 bushings use centrifugally cast SAE 660 bronze with precise tolerances, validated by field trials.
Fleet operators report that genuine XCMG bushings last 3-4 times longer than aftermarket copies, maintaining tight articulation with zero slop for over 8,000 hours. Protect your grader’s frame and pivot pins from oval wear. Choose safety, reliability, and performance with authentic 381600397 bushings.
The 381600397 bronze bushing is stocked in XCMG regional warehouses across North America, Europe, Asia-Pacific, the Middle East, and Africa. Standard lead time is 5-7 working days. Express freight available for urgent repairs. Bulk orders (50+ pieces) receive volume discounts.
Each bushing is individually wrapped in oiled paper to prevent corrosion. Technical datasheets, installation drawings, and material certificates are available electronically. XCMG parts specialists offer remote support for articulation joint rebuilds.
A large infrastructure contractor in Australia replaced worn aftermarket bushings on 18 XCMG GR215 graders with genuine 381600397 bushings. After 6,000 operating hours, articulation slop was measured at less than 2 mm (new spec), compared to 15 mm with aftermarket bushings at 3,000 hours.
In Canadian mining operations at -40°C, the 381600397 bushing maintained low friction and no galling, while aftermarket bushings often seized or cracked. Operators reported smoother articulation and reduced greasing intervals.
The 381600397 is available as a single bushing or in bulk packs (5, 10, 25 pieces). Custom sizes (ID, OD, length) can be ordered with a 15-day lead time. Minimum order for custom sizes is 10 pieces.
For fleet managers, XCMG offers articulation rebuild kits that include the 381600397 bushing, matching pin, seals, and grease fittings. Kits come with installation instructions and torque specifications. Contact our parts team for consignment stock arrangements.
To maximize service life of your 381600397 bronze bushing, grease the articulation points every 250 operating hours or weekly. Use NLGI #2 lithium-based grease with EP additives. Check for radial play annually – replace if play exceeds 3 mm measured at the pin end.
If the bushing is worn oval, inspect the housing bore for damage before installing a new bushing. Always replace the pivot pin at the same time as the bushing. Genuine XCMG bushings typically provide 8,000-12,000 hours of reliable service under normal conditions.
In summary, OEM number 381600397 represents the industry standard for XCMG motor grader articulation bearings. From alloy selection to precision machining, every detail meets the highest durability requirements. Never risk pivot slop or frame damage. Order the genuine 381600397 bronze bushing for your fleet today and experience the XCMG quality difference.
With proven reliability in thousands of graders worldwide, the 381600397 bushing continues to outperform aftermarket alternatives. Ensure smooth articulation, reduced wear, and extended component life. Choose genuine XCMG for your grader’s pivot points. Secure your fleet’s uptime with OEM authenticity.
