Product Features
Advanced Al-Fin Insert for First Ring Groove Protection: To counter the sudden heavy loads typical in construction machinery, an austenitic Ni-resist (Al-Fin) insert is metallurgically bonded into the first ring groove. This delivers a heavy-duty, wear-resistant surface that prevents the groove from widening, scoring, or early cracking under high-frequency reciprocating impacts, ensuring long-lasting gas sealing.
Micron-Level Barrel Skirt Profile with Superior Friction and Vibration Reduction: The piston skirt incorporates a micron-level precision asymmetric oval-barrel profile. This advanced geometry ensures flawless kinematic compliance with the cylinder liner across both cold and hot operating temperatures, eliminating engine slap noise while drastically reducing contact wear. Strict OEM weight tolerance control further guarantees smooth engine operation.
Important Notice
