aluminium cylinder ø 45,5 for mbk 50 cc

Description

ALUMINIUM CYLINDER

• Cylinders obtained by gravity die-casting in permanent steel moulds.
• Material: hardened and tempered high silicon content primary aluminium alloy.
• Machining: on numerically controlled high precision machine tools.
• Cylinder liner with silicon carbide metal-spray coating on a galvanic nickel matrix, cross-honed with passes with diamonds for very tight tolerances.
• Heat exchange surfaces recalculated.
• Exhaust and transfer ports designed and tested for maximum thermodynamic performance.
• Rings in very strong nodular cast iron with ground, wear-resistant, hard chrome metal-spray coating on the contact surface.
• Shape and surface texture dimensional checks.
• Cylinder and piston selected for a fit of 0.010-0.005 mm.
• Checking of all the seals carried out.

PISTON

• Material: special aluminium alloy with high silicon content and low thermal expansion.
• Machining: on numerically controlled machine tools.
• Lightened and strengthened.
• Heat exchange surfaces increase.

PISTON RINGS

• Rings in very strong modular cast iron with ground, wear-resistant, hard chrome metal-spray coating on the contact surface.
