Low-fin density/weight/count finned tubes, commonly referred to as LFW type finned tubes, are specialized heat transfer components widely employed in diverse industrial applications. Their design incorporates an array of thin fins extending from a smooth tube surface, significantly increasing the heat exchange rate/thermal conductivity/surface area

Piston rod bearings are crucial components in internal combustion engines, facilitating smooth rotation between the piston and the connecting rod. Their effectiveness heavily influences engine durability. The design of these bearings involves intricate considerations of materials, geometry, and lubrication to withstand the rigorous operating condit
