Main bearing grinding is a process used to recondition the main bearings of an engine. Main bearings are the bearings that make contact with the crankshaft and allow the engine to rotate. These bearings are important for the smooth running of the engine. Engine bearings can wear and deteriorate over time. In this case, main bearing grinding is necessary. The main bearing grinding process involves dimensioning, smoothing and polishing the surfaces of the main bearings. This process allows the bearings to be reconditioned and the functionality of the engine to be restored.

The main engine grinding process can vary depending on the type of engine, frequency of use and other factors. However, as it is often necessary to completely disassemble the engine, the main engine grinding is carried out as part of a more comprehensive engine repair process. Bearing grinding is particularly useful when worn or damaged bearings need to be reconditioned. It helps to increase the performance, reliability and lifetime of the engine. However, it must be carried out by a specialist with the appropriate equipment and know- how. An incorrect operation can lead to further damage to the engine.
