Malossi aluminum thermal unit D 75,5 piston pin 15 LC

The Malossi Ø 75.5 thermal unit is a high-quality product made of aluminum, specifically designed for 4-stroke mopeds.

The cylinder is made of a primary alloy of silicon-hardened aluminum, with a silicon carbide coating in a galvanic nickel matrix. The processing is carried out on high-precision CNC machines, ensuring very tight tolerances. The coupling between the cylinder and the piston is selected with a precision of 0.05 mm. The heat exchange surfaces have been recalculated and increased to ensure optimal efficiency.

The piston is super compact and made of a special primary alloy of low thermal expansion silicon aluminum, with tin-coated sliding walls. The piston is also processed on CNC machines, ensuring maximum precision. It has been lightened and reinforced to improve performance. The heat exchange surfaces have been increased to ensure efficient cooling.

The thermal unit segments are of high quality. The compression segment is made of special nitrided steel, ensuring high sliding and high mechanical resistance. The first oil scraper is made of chromed S10 spheroidal cast iron, while the second oil scraper is made up of three pieces of chromed alloy steel.

This Malossi Ø 75.5 thermal unit offers high-level characteristics and advantages, thanks to its precise construction and choice of quality materials. It guarantees optimal performance and efficient cooling, improving the performance of the moped.
