Product Advantages

1. OEM Standard Precision Matching Produced in strict accordance with Komatsu SAA6D107E engine's original factory drawings and high-precision tolerance standards, the inner diameter, outer diameter, wall thickness and matching size are perfectly consistent with the original parts, ensuring a tight and precise fit with mating components, no secondary processing required for installation.

2. Dual-material Composite Structure Optimization The alloy steel base ensures high structural strength, rigidity and fatigue resistance; the wear-resistant copper alloy inner layer provides excellent antifriction and wear performance. The two materials are firmly bonded by advanced hot pressing process, no delamination or falling off, with super structural stability.

3. Advanced Surface Treatment & Forming Process Adopts precision cold extrusion and honing forming process, the inner surface finish reaches a high precision level, which is conducive to the rapid formation and stable retention of the oil film; the edge is chamfered and deburred to avoid scratching the mating shaft and components during installation and operation.

4. Strong Adaptability to Harsh Working Conditions Passed professional performance tests such as high-temperature load, continuous vibration, wear resistance, seizure prevention and oil film retention. It can work stably in the harsh working environment of heavy-duty engineering machinery such as high load, high speed, frequent start-stop and severe vibration, fully adapting to the operation requirements of SAA6D107E engine.

5. Long Service Life & High Cost Performance The product performance is close to Komatsu original genuine parts, the wear rate is reduced by more than 40% compared with ordinary bushings, effectively extending the service life of the bushing and mating components, reducing the frequency of engine maintenance and replacement, lowering the downtime loss of engineering machinery and the overall operation and maintenance cost.

Installation & Maintenance Tips

1. Clean the bushing installation hole and mating shaft surface before installation, remove oil stains, rust, burrs, impurities and old seal residues, and ensure the mating surface is smooth, flat and free of obvious scratches.

2. Install the bushing in the correct direction according to the marking (if any), avoid reverse installation; press the bushing into the installation hole evenly with a special press and positioning tool, do not strike hard to prevent bushing deformation, cracking or damage to the mating surface.

3. Ensure the lubricating oil passage and oil groove (if any) are unobstructed before starting the engine, and pre-lubricate the bushing inner surface with engine oil to form an initial oil film and avoid dry friction during cold start.

4. After installation, check the coaxiality and rotation flexibility of the mating shaft and bushing, ensure there is no jamming or abnormal friction; fasten the related fixing components according to the specified torque in the SAA6D107E engine manual.

5. Regularly check the engine oil quality, oil level and lubrication status of the bushing installation position; replace the lubricating oil and oil filter according to the maintenance cycle. If abnormal engine noise, vibration or mechanical jamming is found, stop the machine for inspection in time to avoid bushing damage and engine fault expansion.
