9R-0162
The 9R0411 sleeve bearing is a premium OEM-compatible component designed exclusively for Caterpillar BACKHOE LOADERS, serving as a direct replacement for the OEM part number 9R0162. Engineered to thrive in heavy-duty excavating and material handling environments, this high-performance bushing delivers exceptional durability, wear resistance, and operational stability for Caterpillar models including 424D, 426, 438, 416, 436C, 446B, and more. Crafted with precision to meet or exceed Caterpillar’s strict standards, the 9R0411 bushing is a reliable solution for construction, mining, and industrial applications where equipment downtime is costly and performance is non-negotiable. Its core design focuses on reducing friction, absorbing impact, and extending component lifespan—making it a top choice for fleet managers and heavy machinery operators worldwide.
At the heart of the 9R0411 bushing lies composite wear-resistant materials that redefine durability. The outer layer features high-strength Q235A low-carbon steel as a supporting skeleton, while the inner layer is sintered with either ZCuSn10Pb1 copper-based alloy or PTFE+bronze powder polymer composite. This dual-layer structure boasts a friction coefficient of ≤ 0.12 and a wear-resistant layer thickness of ≥ 2mm, enabling it to withstand surface contact pressure exceeding 200MPa—ideal for the most demanding excavation conditions. The copper alloy liner undergoes solid solution aging treatment, achieving a hardness of HB200-250, ensuring resistance to deformation even under extreme loads.
The 9R0411 incorporates a innovative self-lubricating design with solid lubricants like molybdenum disulfide embedded in the lining material. This eliminates the need for frequent oiling, extending the maintenance cycle to 800 hours—double the lifespan of traditional bushings that require servicing every 400 hours. For operators, this translates to reduced downtime, lower maintenance costs, and uninterrupted productivity in critical projects.
Precision is paramount in heavy machinery components, and the 9R0411 excels with dimensional tolerance control that meets industry-leading standards. The inner diameter follows H7 tolerance (e.g., 50mm inner diameter with +0.025mm tolerance), maintaining a fit clearance of 0.03-0.08mm with the pin shaft to ensure low-vibration operation. The outer diameter adheres to js6 tolerance, achieving an interference fit accuracy of ≤ 0.01mm with the installation hole—preventing loosening or detachment during high-intensity use.
The 9R0411 features two key surface treatment processes that boost longevity and functionality. The steel back undergoes phosphating (film thickness 5-8μm) to enhance adhesion with installation holes, while the copper alloy lining is machined with spiral oil grooves (pitch 12mm) that increase oil storage capacity by 30%. This design ensures even distribution of lubricating grease, further reducing friction and protecting against corrosion in harsh working environments.
The 9R0411 is fully compatible with a wide range of Caterpillar BACKHOE LOADER models, including 424D, 426, 438, 416, 436C, 446B, 428, 424B, 420D, 442D, 430D, 432D, 436, 428D, 416C, 438C, 426C, 416D, 438D, 428C, 420F, and 430F. It is engineered to fit seamlessly into hinge points, boom lifting cylinders, and bucket connections—critical areas that demand reliability under heavy loads.
Ideal for heavy-duty construction, mining operations, and earthmoving projects, the 9R0411 thrives in environments with frequent impact, dust, and moisture. Whether used for excavating soil, lifting rocks, or handling bulk materials, this bushing maintains performance in temperature fluctuations and abrasive conditions, making it a versatile choice for contractors and mining companies globally. It also supports customizations for other machinery brands, ensuring compatibility beyond Caterpillar when specifications are provided.
