Product Overview
2878168 bushing (BUSHING) is a core precision protective and friction-reducing component designed for heavy-duty diesel engines. Installed at engine movable assembly matching positions, it serves as a buffer and isolation sleeve between rotating and fitting parts. This engine bushing effectively solves common mechanical faults such as metal direct friction wear, component jitter, assembly gap enlargement and abnormal operational noise caused by aging or worn bushings. It optimizes the matching precision of engine moving parts, reduces mechanical loss, and maintains long-term stable and smooth operation of the engine under full-load working conditions.
Core Product Advantages
1. High-Density Wear-Resistant Alloy Material: Adopts high-quality alloy composite material with uniform internal density, featuring excellent friction resistance and compression resistance. It effectively resists long-term high-frequency mechanical friction without excessive abrasion or deformation.
2. Ultra-Precision Dimensional Machining: Strict CNC precision machining ensures accurate overall size and smooth inner and outer surfaces. It fits engine assembly gaps perfectly, eliminates loose matching and offset displacement, and improves overall assembly precision.
3. Excellent Vibration & Noise Reduction: Optimized structural toughness can buffer engine operation vibration and mechanical impact, weaken resonance noise generated by component friction, and improve the stability of engine mechanical operation.
4. High & Low Temperature Resistance: Stable physical performance in extreme temperature range of -40℃ to +135℃, no softening failure in high-temperature engine compartment, no brittle cracking in low-temperature harsh environments.
5. Anti-Corrosion & Anti-Oxidation Performance: Professional surface passivation treatment resists erosion of engine oil, high-temperature gas and dust oxidation, avoiding corrosion and aging failure and extending component service life.
6. Lightweight & Standard Specification: Compact size 16.5cm*16.5cm*1.5cm and lightweight 0.126KG design, no burden on engine operation, standard size supports plug-and-play replacement without secondary trimming or modification.
7. Strict Factory Quality Inspection: Finished products pass wear resistance test, dimensional tolerance calibration and fatigue cycle test, with stable batch quality for engine daily maintenance, overhaul replacement and fleet bulk procurement.
