SSER200 Stainless Steel Bearing

SSER200 Stainless Steel Bearing
Failure analysis of stainless steel outer spherical bearing is also every user must understand, improve the reliability of the work surface system engineering is an important part of the bearing, bearing function in its specified loss, failure or failure as a result of the phenomenon that the bearing failure. Failure of stainless steel outer spherical bearing can be divided into two parts according to their normal failure and early failure, which is mainly aimed at pitting corrosion and fatigue cause early failure of bearing analysis and put forward Suggestions to improve the life and reliability of bearing. The most common and popular microanalysis methods are fracture analysis, optical metallographic analysis, and hardness testing.

SSER200 Stainless Steel Bearing Features

Daily users of stainless steel spherical bearing failure content should include these aspects. Whether the raw materials meet the standards and design requirements.Whether the matrix structure and heat treatment quality of outer spherical bearing parts with seat meet the standard requirements.Whether there are decarburized layer, tortensite and other surface processed metamorphic layer in the surface structure of bearing material. The depth of surface strengthening layer such as carburized layer and the structure of each layer of multi-layer metal, the shape and depth of corrosion pit or crack were measured, and the causes and properties of crack were determined according to the shape of defect and the structure characteristics of both sides.

The degree of deformation, temperature rise, material type, and technological process was judged according to grain size, microstructure deformation, local phase change, recrystallization and phase aggregation. The surface hardness, matrix hardness, hardness uniformity and hardness changes in the failure zone were measured. Fracture observation and analysis. Scanning electron microscope (sem) has the advantages of large depth of field, high magnification, and clear image. The composition of foreign bodies at fracture can be detected by electron microscopy, probe and electron energy spectrum in fatigue source and crack source analysis.

On the surface, or from the surface of the crack, the two target parts carburizing, quenching and other surface heat treatment, if after have uneven hardness, organization, and the internal stress of non-uniform and other adverse, the contact stress generally has the opposite under the influence of ground fissure, if parts surface quality is poor, oxidation and decarburization, poor lubrication, inner surface crack, etc.
