Iron is easy to enter the internal bearing. But it is often difficult to control the amount of control. The bearing room is not the best oil or grease. If oil or grease in the bearing chamber to stay more, in the bearing rotation, it is easy to enter the bearing shaft. In order to facilitate the assembly, a number of manufacturers in the bearing chamber with some oil or grease lubrication effect. So it is best to do dynamic balancing of the bearing. If it can not be applied, it is not allowed to control the bearing in the interior of the deposit.When the bearing is in dynamic balance, it will produce some iron.

It confirms the results of the microprobe measurements carried out using the WDS method. The results of mapping show that three carbonate phases are present in the investigated samples: low magnesium calcite, high-Mg calcite and dolomite. The analysis was carried out with the use of the EDS method.Mapping was executed to differentiate the types of high-Mg calcite and changes in the magnesium content inside single crystals. Measurements were executed in carbonate ground mass.
