Some Questions About Bearing And Bearing Steel Rust?Read

Although the content of Cr in bearing steel is relatively high, it has a certain antirust effect, but the content of Cr in steel is low, and the content of Cr in GCr15 is only about 1.5%. At this time, the Cr element plays a role in improving the mechanical properties of steel. The Cr in bearing steel is to improve hardenability, not to prevent

Factors Influencing the Performance of Ball and Rolling

Roller bearings are also a common type of a rolling bearing. Cylindrical roller bearings can support higher radial loads than similar size ball bearings but lack the capacity to support substantial thrust loads. Tapered roller bearings can support. high radial and high thrust loads and are often used in pairs (See Figures 4 and 5).

stresses - How do ball bearings not crack from a load

Dec 22, 2021· TL;DR: ball bearings deform due to Hertzian pressure and therefore distribute the load. However, the reason balls (rolling elements) don''t easily crack is the ductility of the material (and to some lesser extent the treatment of the material) The Deformation of the bearing balls due to Hertzian pressure contributes to the distribution of the loads and only delays failure.
