Engine Piston S6D108 Komatsu Excavator Parts Anti Expansion Piston Aluminum Alloy
High Quality Machinery Parts Engine Piston S6D108 For Komatsu Motor
The different working temperature of piston and the different expansion characteristics of aluminum alloy piston and cast iron cylinder liner make it difficult to control the gap between piston skirt and cylinder liner. The most efficient skirt shape cannot overcome the differential expansion rate between piston and cylinder.
In addition, the minimum clearance determined under the maximum load of the engine will also cause too large clearance under partial load, resulting in knock noise and increased engine fuel consumption. In order to control the cylinder piston skirt clearance, make it neither too small bite caused cylinder cylinder, and not too big to cause noise and vibration, the piston skirt and pin buried cast symmetry between a pair of steel sheet, and will be appropriately extended around the periphery of the skirt of the steel, together with the surrounding material of the steel bimetallic strip, heat expansion shrinkage along the axis of the piston pin in the vertical direction.
This piston in the ring groove and the skirt of the itd does not open heat insulation groove, heat flow can be smoothly transferred to the skirt, so the first ring groove area of the temperature than the slotted piston, the strength is higher. Aluminum piston is widely used to control thermal expansion by means of steel strip or steel ring.
Piston type and surface treatment : Alfin Reinforcement
Created for operation in high temperature environment like turbo engines.
Moly Skirt : Help produce less frictional heat and engine noise.
Nitriding: The nitriding products have excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance .

Q: We can see from the pictures why the color of our products is darker than ordinary affiliates?
A: That ’s because our pistons are high-silicon and high-nickel, so the color will be darker.
Q: What are the benefits of high silicon and high nickel?
A: We can refer to their performance, we can know that high silicon and high nickel products have better lubricity and higher quality, so their service life will be longer.
Q: In addition to this advantage, does your product have any other highlights?
A: There are also more cooling pipes inside our pistons to facilitate better heat dissipation and make the product last longer.
Q: I want to know about your after sales service
A: I forgot to tell you that our after-sales service is perfect, and we will have someone to deal with problems encountered by customers to ensure you have the best shopping experience..
