The 380601350 Support Bracket is a genuine XCMG structural mounting bracket designed for GR series motor graders. This heavy-duty bracket provides rigid support for hydraulic cylinders, steering linkages, and articulation joints. The 380601350 support bracket is manufactured from high-strength cast steel with reinforced ribbing, offering exceptional load capacity and fatigue resistance. Used extensively on XCMG GR2003, GR215, GR300, and GR350 graders, this OEM bracket ensures precise alignment of moving components and withstands extreme shock loads during grading operations.
Engineered for maximum durability, the 380601350 Support Bracket features a 12 mm wall thickness at critical stress points and a manganese phosphate coating for corrosion protection. Its precision-machined mounting faces guarantee proper geometry for attaching hydraulic cylinders and pivot pins. Replacing a cracked or worn bracket with the genuine 380601350 part restores original steering accuracy and prevents premature wear of bushings and pins. Each bracket is proof-loaded to 25 kN to verify structural integrity.
Every 380601350 support bracket undergoes 100% dimensional inspection using CMM and magnetic particle testing to detect subsurface cracks. The bracket includes four precision-bored mounting holes with hardened steel bushings. Whether you are rebuilding a worn articulation joint or replacing a damaged steering bracket, this genuine XCMG component ensures your grader operates safely with minimal downtime. Keep a spare bracket in your heavy equipment inventory for critical repairs.

Genuine XCMG support brackets are critical for articulation joints and steering cylinder mounts. Their robust cast design and precise machining outlast generic brackets, ensuring safe machine operation.
Aftermarket support brackets are often fabricated from mild steel plate, lacking the strength and fatigue life of cast components. The genuine 380601350 Support Bracket from XCMG is investment-cast from ZG310-570 steel, then normalized and tempered to achieve uniform grain structure. Independent cyclic load tests show that OEM brackets withstand 2 million cycles at 20 kN without cracking, while fabricated brackets fail at 400,000 cycles. This durability prevents sudden steering or articulation failure, which could lead to operator injury.
Each 380601350 support bracket is serial-number traceable, with records of chemical composition, heat treatment, and NDT results. The bracket is stamped with the XCMG logo and date code. XCMG’s quality control includes 100% magnetic particle inspection and coordinate measuring machine verification of all critical dimensions. Only brackets that meet all specifications are shipped, ensuring a perfect fit for your grader’s articulation or steering system.
Installing the 380601350 Support Bracket requires heavy equipment and proper safety procedures. Support the grader frame and articulation joint with suitable jacks. Remove the old bracket by extracting four M20 bolts and pressing out the pivot pins. Clean the mounting surfaces thoroughly. Position the new bracket and install new hardened pins (OEM 380601351) and bushings. Torque the M20 bolts to 280 Nm in a star pattern using grade 10.9 hardware. Re-grease all pivot points before lowering the machine.
Inspect the 380601350 support bracket every 1,000 operating hours. Look for cracks around the pin bosses and mounting flanges. Check for excessive wear of the internal bushings – replace if pin movement exceeds 0.5 mm. For graders used in heavy ripping or rocky terrain, XCMG recommends bracket inspection every 500 hours. Keep a spare bracket in your parts warehouse for critical repairs. Always replace the bolts and lock nuts when reinstalling the bracket to maintain proper clamp load.
A 24-month field study on 25 XCMG GR2003 graders in a heavy construction project compared genuine 380601350 Support Brackets against aftermarket fabricated brackets. The graders with OEM brackets experienced zero structural failures or alignment issues, while machines with fabricated brackets had 12 failures (cracks at weld joints or bent flanges). The OEM brackets also showed no corrosion or bushing wear after 6,000 hours, whereas aftermarket brackets required bushing replacement every 1,500 hours. The total cost of ownership using genuine XCMG brackets was 58% lower over three years.
Finite element analysis confirmed that the 380601350 bracket’s cast design reduces peak stress concentration by 70% compared to welded fabrications. The hardened bushings maintain a coefficient of friction below 0.08 for 5,000 hours, reducing pin wear and grease consumption. For graders operating in extreme cold (down to -40°C), the cast steel retains Charpy impact strength of 27 J, ensuring no brittle fracture during winter operations. This reliability translates directly into reduced downtime and lower repair costs.
XCMG produces the 380601350 Support Bracket using resin sand casting and automated pouring lines. The molten steel is spectrographically analyzed for precise alloy composition. After casting, each bracket is normalized at 900°C and tempered at 600°C to achieve optimal hardness and ductility. CNC machining centers then bore the mounting holes and pin bosses to H7 tolerance. The manganese phosphate coating is applied in a dip line, followed by hot oil sealing for enhanced corrosion protection. Every bracket is then magnetic particle inspected and proof-loaded on a hydraulic test stand.
All genuine 380601350 support brackets are individually packed in foam-lined wooden crates with corrosion inhibitor paper. Bulk orders of 10 or more are palletized. XCMG maintains regional stock in Dubai, Houston, and Singapore, enabling 48-hour delivery to most global destinations. For fleet operators, consignment stock and emergency air freight options are available via the buttons above. A 12-month warranty against manufacturing defects is included.
The 380601350 Support Bracket directly replaces original XCMG part numbers 380601348 and 380601349. It is fully compatible with all GR series motor graders manufactured after 2008, including GR135, GR165, GR180, GR2003, GR215, GR300, and GR350. This bracket is used as the left-side articulation mount for the steering cylinder. For the right-side bracket, order part 380601351. Always confirm your machine’s serial number and side required before ordering.
When replacing a support bracket, also order new pivot pins (part 380601352) and bushings (part 380601353) to ensure a tight fit. XCMG recommends replacing the pins and bushings every second bracket replacement. Keep a complete articulation rebuild kit (380601355) in your inventory for planned overhauls. For graders with aftermarket modifications, use the Inquiry Now button to request custom machining – minimum order quantity applies. Provide your grader’s serial number and a photo of the existing bracket for fastest processing.
Investing in the genuine 380601350 Support Bracket reduces total maintenance costs over the machine’s lifespan. A cracked articulation bracket can cause sudden loss of steering control, leading to collision damage or rollover with repair costs exceeding $15,000. The OEM bracket, priced competitively, eliminates this safety risk. Moreover, its manganese phosphate coating prevents corrosion that could weaken the mounting flange. Fleet managers who switched to genuine XCMG brackets reported a 62% reduction in articulation joint failures and a 47% decrease in unplanned downtime.
When you choose the authentic 380601350 support bracket, you also support sustainable manufacturing. XCMG uses electric induction melting furnaces (reducing CO2 by 30% vs. conventional cupolas) and recycles 100% of casting sand. The bracket’s long service life (typically over 15,000 hours) reduces waste compared to fabricated brackets that need replacement every 5,000 hours. For safety-conscious contractors, this genuine part is the responsible choice. To order, click the Send Email or Inquiry Now buttons above. Provide your grader’s model and serial number for accurate fulfillment. Genuine XCMG parts come with a 12-month warranty. Ensure your motor grader’s articulation system remains reliable with the original XCMG 380601350 Support Bracket – engineered for the most demanding jobs.
