Sliding bearings are used in combustion engines for the crankshaft and camshaft. The bearing shells are often composed of three layers whereby the inner layer is only metallised or sputtered. If there are residues on the bearing shell, the inner layer has too little purchase and flakes off. The system from Micro-Epsilon checks all bearing shells at the end of the production for a faultless condition of the surface. A BV camera records an image of each shell which is evaluated afterwards completely automatically. If necessary, the system also takes over the selection afterwards depending on the measurement result.
