Malossi aluminum cylinder D 75,5 piston pin 15 LC for 3117542

The Malossi Ø 75.5 aluminum cylinder is a high-quality product designed for 4-stroke mopeds. Made with a primary alloy of silicon-enriched tempered aluminum, the cylinder features a silicon carbide coating in a galvanic nickel matrix and a cross-hatch honing with two diamond passes, ensuring extreme precision with very tight tolerances. The machining is carried out on high-precision CNC machines, ensuring a perfect coupling between the cylinder and piston with a selection of 0.05 mm. The heat exchange surfaces have been recalculated and increased, ensuring optimal efficiency.

The super compact three-segment piston is made with a special primary alloy of low thermal expansion silicon-aluminum with a tin coating on the sliding walls. The piston is also machined on CNC machines, ensuring superior quality. Additionally, the piston has been lightened and reinforced to improve performance. The heat exchange surfaces have been increased, ensuring excellent heat dissipation.

Finally, the cylinder rings are of high quality. The compression ring is a special high-sliding and high-strength ring made of nitrided special steel. The first oil scraper ring is chrome-plated spheroidal cast iron S10, while the second oil scraper ring consists of three pieces of chrome-plated alloy steel.

In summary, the Malossi Ø 75.5 aluminum cylinder is a product of the highest quality, made with precision materials and processes. Thanks to its characteristics, it offers superior performance and excellent heat dissipation, ensuring efficient and reliable operation.
