Bearing shells have the function to unroll and support rolling elements. In four-stroke engines, for example, the connecting rod, which connects the piston to the crankshaft, rotates in a bearing. This is lubricated with oil, which reduces the friction and thus wear. In the lubricant, however, various residual dirt particles are contained, which can settle in the bearing shell. In the past, the [...]
