“Smooth” is not always better than “rough” when it comes to pistons…

Did you know?... “Smooth” is not always better than “rough” when it comes to pistons…

Features like ring grooves are made extremely smooth, while others like the skirt are intentionally made with a fine texture on the surface. Surface contact area, oil film retention, and minimizing friction are all key criteria when we choose the process, tools, and running parameters in manufacturing. We back this up with frequent checks on highly sensitive roughness measuring devices. These details make all the difference!
