The Cummins 2AZ-FE diesel engine piston is designed for reliable operation under high-temperature and high-pressure working conditions. It receives the force generated during combustion and transfers it to the connecting rod through the piston pin, helping convert combustion energy into mechanical power.

Manufactured from quality aluminum alloy and precisely machined to match engine requirements, the piston supports stable compression, efficient heat dissipation, smooth reciprocating movement, and reduced mechanical wear. It is suitable for engine repair, rebuilding, and aftermarket replacement applications.

Product Specifications

Product Features

High-Quality Aluminum Alloy

The piston is manufactured from carefully selected aluminum alloy, providing a practical balance of strength, low weight, thermal conductivity, and resistance to high operating temperatures.

Precision Machining

Critical dimensions such as the piston diameter, ring grooves, piston pin bore, and skirt profile are accurately machined to support proper installation and stable engine operation.

Efficient Heat Dissipation

The piston helps transfer combustion heat through the piston rings and cylinder wall, reducing the risk of excessive thermal deformation and premature component failure.

Accurate Ring Groove Design

Precisely machined ring grooves allow the compression rings and oil control ring to operate correctly, supporting combustion sealing, oil regulation, and heat transfer.

Stable and Durable Performance

The piston crown, skirt, ring lands, and pin boss areas are designed to withstand repeated combustion pressure and mechanical loading in diesel engine applications.

Reduced Friction and Wear

The finished skirt surface and controlled dimensions help maintain stable movement inside the cylinder, reducing abnormal friction, noise, and uneven wear.
