Our heavy-duty truck synchronizer sleeve achieves ISO 6-8 level tooth profile accuracy with a tooth surface roughness of Ra ≤ 1.6 μm, guaranteeing smooth meshing and ultra-low operating noise. The tooth alignment error is strictly controlled within 0.02 mm after heat treatment, ensuring perfect dimensional stability and precise assembly fit, which eliminates transmission vibration and improves overall power transmission efficiency.
With a rated torque capacity of 1000 lb-ft, this dump truck transmission part is specifically engineered to withstand the extreme loads encountered in construction and mining dump truck operations. It is fabricated from high-grade steel that offers excellent impact resistance and wear resistance, preventing premature failure under frequent start-stop and heavy-haul conditions.
We employ state-of-the-art carburizing treatment to achieve a surface hardness of 58-62 HRC with an infiltration layer depth of 0.8-1.2 mm, creating a hard, wear-resistant surface while maintaining a tough, ductile core. Additionally, shot peening treatment introduces residual compressive stress, which extends the fatigue life of the EIRO CNC synchronizer sleeve by 20%-30% compared to standard products.
Manufactured to exact OEM dimensions, this synchronizer sleeve is a direct drop-in replacement for original EIRO transmission parts, requiring no modifications during installation. This significantly reduces repair time and labor costs for truck parts distributors and maintenance workshops.
