Marine diesel engine parts include PISTON ROD, CROSSHEAD PIN, and PISTON MODULE. The PISTON ROD is a critical component that compresses gas to convert thermal energy into kinetic energy in the combustion chamber. The company produces all types of piston rods for 2-stroke Engines, including S26MC~S90MC/ME-C, G45ME-C~G95ME-C, RTF35~RTF96, and WX35~WX92. The CROSSHEAD PIN plays a vital role in converting the reciprocating motion of the PISTON into the rotational motion of the CRANK SHAFT. It connects the PISTON ROD and CONNECTING ROD, facilitating vertical reciprocating motion guided by the GUID SHOE. All types of crosshead pins for 2-stroke Engines, such as S26MC~S90MC/ME-C, G45ME-C~G95ME-C, RTF35~RTF96, and WX35~WX92, are manufactured. The PISTON MODULE is an ASSY part assembled from PISTON ROD, CROWN, SKIRT, and COOLING INSERT.MarinedieselenginepartsincludePISTONROD,CROSSHEADPIN,andPISTONMODULE.ThePISTONRODisacriticalcomponentthatcompressesgastoconvertthermalenergyintokineticenergyinthecombustionchamber.Thecompanyproducesalltypesofpistonrodsfor2-strokeEngines,includingS26MC~S90MC/ME-C,G45ME-C~G95ME-C,RTF35~RTF96,andWX35~WX92.TheCROSSHEADPINplaysavitalroleinconvertingthereciprocatingmotionofthePISTONintotherotationalmotionoftheCRANKSHAFT.ItconnectsthePISTONRODandCONNECTINGROD,facilitatingverticalreciprocatingmotionguidedbytheGUIDSHOE.Alltypesofcrossheadpinsfor2-strokeEngines,suchasS26MC~S90MC/ME-C,G45ME-C~G95ME-C,RTF35~RTF96,andWX35~WX92,aremanufactured.ThePISTONMODULEisanASSYpartassembledfromPISTONROD,CROWN,SKIRT,andCOOLINGINSERT.
