Core Functions
1. Wear Resistance & Vibration Damping: Isolates metal-to-metal direct contact between engine mating components, reduces friction and wear during engine high-speed operation, and effectively absorbs and buffers mechanical vibration to stabilize engine running status.
2. Positioning & Centering: Precisely positions the matching shaft and hole components of the engine, ensures accurate alignment of mechanical transmission parts, prevents offset caused by long-term operation, and maintains the precision of engine internal transmission.
3. Load Bearing & Force Distribution: Evenly distributes the dynamic and static loads generated during engine operation to the connected structural parts, avoids local stress concentration, and protects the integrity of related engine components.
4. Sealing Auxiliary: Forms a secondary protective seal between mating parts in specific engine positions, prevents the leakage of lubricating oil and the intrusion of dust, impurities and other foreign matters, and extends the service life of the internal lubrication system.
Product Advantages
1. OEM-Grade Compatibility: 1:1 replication of Komatsu original bushing's dimensional parameters and structural design, no secondary processing required for installation, perfectly matching SA6D170E/SAA6D170E engine's assembly groove, avoiding fit clearance errors.
2. High-Quality Material Selection: Adopts high-strength alloy copper-based/ferrous-based wear-resistant material (customized for Komatsu engine working conditions) with high hardness, excellent wear resistance and corrosion resistance, able to withstand high temperature, high pressure and heavy load of engine long-term continuous operation.
3. Precision Machining: Processed by high-precision CNC equipment, the inner and outer surface finish reaches the original standard, the dimensional tolerance is controlled within ±0.005mm, ensuring smooth assembly and stable operation performance.
4. Long Service Life: Under the condition of standard installation and regular maintenance, the service life is equivalent to the original parts, which reduces the frequency of engine disassembly and replacement, and lowers the later maintenance cost of the whole machine.
5. Stable Performance Under Harsh Conditions: Adapt to the complex working conditions of construction machinery (high altitude, high temperature, heavy dust, continuous operation), no deformation or performance attenuation, ensuring the reliable operation of Komatsu engine in various construction scenarios.
Application Scope
Special for Komatsu heavy-duty construction machinery equipped with SA6D170E/SAA6D170E engine, including large excavators, bulldozers, loaders, mining dump trucks and other engineering equipment.
