The bearing extractor is designed to remove the bearing from the shaft and replace it with a new one in the same position. It is a hydraulic tool with manual operation, which lacks any dangerous manipulation, such as shaft disassembly. The process is quick and effective, preventing possible damage to the stern tube or shaft. The shaft remains in place and the bearing can be replaced in a few minutes. The equipment is designed to work with 2 sizes of basic kits that cover bearings with outer diameters up to 100mm. The kits are: T8: for bearings with an outer diameter up to 58 mm. T13: for bearings with diameters between 58 mm and 100 mm (for shafts of 50-80 mm).
