Built to meet your engine’s demands and lower your costs through remanufacturing

Pistons, rings, liners, and rods form the heart of your engine, controlling the combustion process and transferring mechanical energy to the crankshaft. To protect your engine from harsh conditions, CNA Pistons, Rings, Liners, and Rods are:

• designed to work and wear as a system in your CNA engine for smooth, efficient operation and long life.
• manufactured and tested to close tolerances to ensure top engine performance.
• heat treated to deliver strength and durability during engine operation.

Quality materials and controlled manufacturing processes also mean CNA Pistons, Rings, Liners, and Rods can be remanufactured for a second life. CNA Cylinder Packs offer same-as-new performance, long life, and quick turnaround—all at fraction-of-new prices.

Quality materials and controlled processes ensure top performance and long life

CNA Pistons, Rings, Liners, and Rods are designed and manufactured using quality materials and controlled processes for maximum performance and durability.

• Precise plasma or chrome plating guarantees exceptionally long wear life.
• Proper surface finish provides smooth operation and long wear life.
• Barrel-faced top ring maintains the proper oil film thickness on the cylinder liner for reduced liner damage and oil consumption.
• Durable heat-treated ductile iron construction resists breaking and impact loading.
• Precise fit with grooves ensures proper oil control and sealing between the crankcase and combustion chamber for efficient operation, long wear life and reduced blow-by.

Competitive rings

• Thin chrome plating can reduce wear life.
• Soft, gray iron construction can reduce durability and lead to failure.

Competitive liners

• Lack of heat treating and roll burnishing can lead to flange cracks and breaks.
• Random cross hatch pattern can result in poor oil control and increased oil consumption.
