439LW00100001 MAHLE Cylinder Liner

MAHLE's Cylinder Components are designed for use within crankcase systems as cylinder liners. They offer improved thermal conductivity and reduced friction, leading to increased engine performance and lifespan. The MAHLE part number is 439LW00100001, with a size of 336.0 x 174.0 x 174.0 mm and made in Austria. Dimensions are provided by the supplier and may include packaging dimensions. Cylinder liners are precision-honed, tubular components installed within the engine block to create the combustion chamber’s sealing surface. Typically utilized in heavy-duty and high-performance engines, they provide a durable, replaceable wear surface for piston travel. Liners are constructed from cast iron, steel, or coated alloys, optimized for heat dissipation and minimizing friction. Wet liners are directly cooled by engine coolant, while dry liners rely on the block for thermal management. Precise dimensional control and surface finish are critical for maintaining compression and preventing oil consumption.
