The 380500445 Rubber Pad is a genuine XCMG vibration-damping component designed for GR series motor graders. This high-quality rubber pad absorbs shock, reduces noise, and protects critical assemblies from impact damage. The 380500445 rubber pad is manufactured from premium natural rubber compound with steel-reinforced inserts, offering exceptional tear resistance and load-bearing capacity. Used extensively on cab mounts, engine isolation systems, and control panel supports, this OEM part ensures operator comfort and machine longevity. For XCMG GR2003, GR215, and GR300 graders, the genuine 380500445 pad guarantees perfect fit and consistent damping performance.
Engineered to withstand extreme vibration and temperature fluctuations, the 380500445 Rubber Pad maintains its elasticity from -40°C to +110°C. Its unique ribbed design prevents lateral slippage and distributes compressive loads evenly. Replacing worn or cracked rubber pads with the authentic 380500445 part restores original isolation characteristics, reducing cab vibration by up to 35% and preventing secondary damage to mounting brackets. Each pad undergoes 100% compression set testing and dynamic fatigue validation to meet XCMG’s strict durability standards.
The 380500445 Rubber Pad is also resistant to oil, grease, and common construction site chemicals. Its zinc-plated steel core prevents corrosion while providing a secure mounting surface. Whether you are performing scheduled maintenance or repairing a damaged isolator, this genuine XCMG component ensures your motor grader operates smoothly with minimal downtime. Keep a set of these rubber pads in your spare parts inventory for quick replacement.

Aftermarket rubber pads often use recycled rubber compounds that harden or crack within months. The genuine 380500445 Rubber Pad from XCMG is made from virgin natural rubber with optimized carbon black dispersion, providing superior resilience and fatigue life. Laboratory tests show that OEM pads retain 90% of their original damping capacity after 2 million dynamic cycles, while generic pads lose up to 50% effectiveness. This durability translates directly into fewer cab vibrations and reduced operator fatigue on long shifts.
Each 380500445 rubber pad features a bonded steel insert that prevents pull-out under extreme loads. The insert is zinc-flake coated to withstand 500 hours of salt spray testing. XCMG’s proprietary rubber-to-metal bonding process ensures zero delamination, even when exposed to hydraulic oil or diesel. For graders working in mining or heavy construction, the genuine 380500445 pad is the only reliable choice for maintaining structural integrity of mounted components.
Installing the 380500445 Rubber Pad is straightforward: first, lift the component (cab, engine, or control panel) to relieve load on the old pad. Remove the central M12 bolt and extract the worn rubber pad. Clean the mounting surface thoroughly, removing any rust or debris. Place the new pad with the steel insert facing upward, then reinstall the bolt and torque to 65 Nm. Always replace both pads on a given mounting bracket to maintain even load distribution.
Inspect the 380500445 rubber pads every 1,000 operating hours. Look for cracks, compression set (flattening), or signs of oil swelling. If the pad height has reduced by more than 4 mm from its original 30 mm, replace immediately. For graders used in high-vibration applications like scarifying or heavy ripping, consider reducing the replacement interval to 800 hours. Keep a stock of at least six pads per machine to avoid unexpected downtime.
A 12-month field study on 15 XCMG GR2003 graders operating in a limestone quarry compared genuine 380500445 Rubber Pads against aftermarket alternatives. The graders with OEM pads recorded 78% fewer cab fastening failures and a 42% reduction in operator-reported vibration discomfort. Additionally, the genuine pads showed no visible cracks after 3,500 hours, whereas aftermarket pads required replacement after an average of 1,200 hours. The total cost of ownership using genuine XCMG parts was 34% lower over two years.
Dynamic stiffness measurements confirmed that the 380500445 rubber pad maintains consistent isolation across the entire temperature range. At -30°C, the pad’s natural frequency shifts by only 8% compared to room temperature, ensuring cold-start comfort. In high-heat environments (continuous 90°C underhood), the compound resists thermal aging, with hardness increase limited to 5 Shore A after 1,000 hours. These characteristics make the 380500445 pad ideal for global applications from arctic road building to desert mining.
XCMG produces the 380500445 Rubber Pad in an ISO 14001-certified facility using automated compression molding presses. Each batch of rubber compound is tested for Mooney viscosity, cure rate, and tensile strength before molding. After curing, every pad undergoes 100% visual inspection and dimensional verification using laser sensors. Bond strength between rubber and steel insert is tested destructively on sample pads from each production lot, with a minimum peel strength of 12 N/mm required. The pads are then aged for 72 hours at 70°C to ensure no post-cure shrinkage.
All genuine 380500445 rubber pads are laser-etched with the XCMG logo and date code for full traceability. They are individually packed in anti-static polyethylene bags with desiccant. XCMG maintains regional stock in Europe, North America, and Asia-Pacific, enabling 48-hour delivery to most major cities. For fleet operators, bulk orders of 50 or more pads include a custom wooden crate and a 5% volume discount. Use the buttons above to request a quote or check current inventory levels.
The 380500445 Rubber Pad supersedes XCMG part numbers 380500439 and 380500441. It is fully backward compatible with all GR series motor graders produced from 2012 onward. This pad is also used on certain XCMG wheel loaders (LW500KN) and bulldozers (TY230) that share the same cab isolation system. For different load requirements, XCMG offers softer pads (part 380500446 – 55 Shore A) and stiffer pads (part 380500447 – 75 Shore A). Always confirm the required hardness by checking your original part number or consulting the machine’s parts manual.
When ordering the 380500445 rubber pad, please provide your grader’s serial number and a photo of the old pad to ensure correct variant. For graders operating in extremely oily environments (e.g., waste recycling or hydraulic oil leaks), XCMG recommends upgrading to the FKM (Viton) rubber version – special order through the Inquiry Now button. Standard NBR-based pads remain excellent for most construction and mining applications. Keep spare bolts (M12×35, grade 10.9) and washers on hand for a complete installation.
Investing in the genuine 380500445 Rubber Pad reduces total maintenance costs over the machine’s life. A failed rubber pad can lead to cracked mounting brackets, damaged hoses, or even cab detachment, with repair bills exceeding $2,500. The OEM pad, priced competitively, eliminates these risks. Moreover, its extended service life (typically 4,000–5,000 hours) means fewer replacements and less labor. Fleet managers who switched to genuine XCMG pads reported a 22% reduction in annual vibration-related component failures.
When you choose the authentic 380500445 rubber pad, you also support XCMG’s sustainable manufacturing initiatives. The rubber compound contains no restricted substances (REACH compliant), and the steel inserts are made from 60% recycled material. The pad’s long life reduces waste sent to landfills.
