The 380500446 Bend Plate is a genuine XCMG structural bracket designed for GR series motor graders. This precision-formed steel plate provides rigid mounting for hydraulic valves, control levers, and electrical junction boxes. The 380500446 bend plate is manufactured from high-strength hot-rolled steel with a 90-degree bent flange, offering superior stiffness and vibration resistance. Used extensively on XCMG GR2003, GR215, GR300, and GR350 graders, this OEM bend plate ensures accurate alignment of attached components and withstands heavy dynamic loads.
Engineered for maximum durability, the 380500446 Bend Plate features a 6 mm base thickness with reinforced gussets at the bend radius. Its black powder-coated finish provides 500 hours of salt spray resistance, making it suitable for corrosive environments including coastal roadworks and mining sites. Replacing a cracked or bent plate with the genuine 380500446 part restores original geometry, preventing misalignment that can cause premature wear of hydraulic hoses and control linkages.
Each 380500446 bend plate undergoes 100% dimensional inspection using CMM equipment to guarantee precise hole locations and bend angle (90° ±0.5°). The plate includes pre-installed M10 weld nuts on the back side for easy component attachment. Whether you are rebuilding a damaged control console or reinforcing a mounting point, this genuine XCMG component ensures your grader operates reliably with minimal downtime.

Genuine XCMG bend plates are critical for mounting hydraulic valves and control systems. Their robust construction and precise geometry outlast generic brackets, ensuring reliable machine operation.
Aftermarket bend plates often use thinner steel (4 mm or less) with inconsistent bend angles, leading to component misalignment and vibration fatigue. The genuine 380500446 Bend Plate from XCMG uses 6 mm Q345B high-strength steel with a controlled 90° bend radius. Independent fatigue tests show that OEM plates withstand 1.5 million vibration cycles without cracking, while generic plates fail at 400,000 cycles. This durability prevents hydraulic line chafing and electrical connection failures.
Each 380500446 bend plate is traceable to its heat number, with records of bend angle verification and coating thickness. The plate includes laser-engraved XCMG part number and production date. XCMG’s quality control includes 100% go/no-go gauge inspection of all mounting holes and weld nut placement. Only plates that meet all specifications are shipped, ensuring a perfect fit for your grader’s control console or valve bank.
Installing the 380500446 Bend Plate requires basic hand tools. First, remove the old bracket and clean the mounting surface on the grader frame. Position the new bend plate so that the 90° flange faces the intended direction (consult your parts manual). Secure the plate using six M10 grade 8.8 bolts (not included) torqued to 48 Nm in a star pattern. Attach components (valves, levers, or junction boxes) to the pre-installed weld nuts using M10 bolts. Do not exceed 50 Nm to avoid stripping the weld nuts.
Inspect the 380500446 bend plate every 1,000 operating hours. Look for cracks near the bend radius or around bolt holes. Check for paint damage that could lead to corrosion. If any deformation is found, replace the plate immediately. For graders used in high-impact applications (e.g., demolition or quarry work), XCMG recommends adding a rubber edge protector to shield the plate from direct rock strikes. Keep a spare bend plate in your parts inventory for rapid field replacement.
A 14-month field study on 22 XCMG GR2003 graders in a highway construction project compared genuine 380500446 Bend Plates against aftermarket brackets. The graders with OEM plates experienced zero bracket failures or misalignment issues, while machines with generic brackets had 9 failures (cracks or bent flanges) requiring component re-alignment. The OEM plates also showed no paint blistering after 5,000 hours, whereas aftermarket plates showed rust within 1,500 hours. The total cost of ownership using genuine XCMG bend plates was 51% lower over two years.
Vibration analysis confirmed that the 380500446 bend plate’s 6 mm thickness and gusset design reduce resonant amplitude by 62% compared to 4 mm generic plates. The captive weld nuts maintain clamp load even after 20 removal cycles, preventing loose attachments. For graders operating in cold climates (down to -40°C), the steel retains impact resistance, with Charpy V-notch tests showing 27 J at -40°C. This ensures no brittle fracture during winter operations.
XCMG produces the 380500446 Bend Plate using a 1000-ton CNC press brake with laser angle feedback. Steel plates are first laser-cut from Q345B coil, then deburred. The bending process uses precision tooling to achieve a 90° angle with an internal radius of 8 mm, preventing stress concentration. After bending, the plate is shot-blasted to SA 2.5 standard, then zinc-primed and powder-coated in an automated line. The coating thickness is measured at 10 points per plate, averaging 80-100 microns. Weld nuts are robotically welded with penetration depth monitoring.
All genuine 380500446 bend plates are individually packed in foam-lined cardboard boxes with a desiccant bag. Bulk orders of 20 or more are shipped in wooden crates. XCMG maintains regional stock in Dubai, Miami, and Shanghai, enabling 48-hour delivery to most global destinations. For fleet operators, consignment stock and fast-ship programs are available via the buttons above. A 12-month warranty against manufacturing defects is included.
The 380500446 Bend Plate directly replaces original XCMG part numbers 380500439 and 380500442. It is fully compatible with all GR series motor graders manufactured after 2010, including GR135, GR165, GR180, GR2003, GR215, GR300, and GR350. This plate is used as a mounting bracket for hydraulic pilot valves, electric joystick consoles, and fuse box enclosures. For left-hand or right-hand variants, XCMG offers mirror-image part 380500447. Always verify the orientation before ordering.
When replacing a bend plate, also order new mounting bolts (part 380500448 – M10×30 grade 10.9) to ensure proper clamp load. XCMG recommends replacing the bolts every second removal to prevent thread fatigue. Keep one spare 380500446 plate in your service truck for emergency repairs. For graders with custom valve stacks, use the Inquiry Now button to request a modified hole pattern – minimum order quantity applies. Provide your grader’s serial number and a photo of the original plate for fastest processing.
Investing in the genuine 380500446 Bend Plate reduces total maintenance costs over the machine’s lifespan. A cracked or bent bracket can cause hydraulic hose chafing, leading to sudden hose failure and oil spill cleanup costs exceeding $1,500. The OEM bend plate, priced competitively, eliminates this risk. Moreover, its corrosion-resistant coating prevents rust jacking that could damage the frame mounting points. Fleet managers who switched to genuine XCMG bend plates reported a 44% reduction in hydraulic hose failures and a 33% decrease in unplanned downtime.
When you choose the authentic 380500446 bend plate, you also support sustainable manufacturing. XCMG uses water-based powder coatings (zero VOCs) and recycles 99% of steel scrap from the cutting process. The plate’s long service life (typically over 15,000 hours) reduces waste compared to cheaper brackets that need replacement every 4,000 hours. For environmentally 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 control systems stay securely mounted with the original XCMG 380500446 Bend Plate – engineered for extreme durability.
