Calculation of the radial or axial displacement |

Rolling bearings have a progressive deflection ╳ |
![]() |
The equations are valid for bearings without misalignment ╳ Deviation of an actual line from a theoretical ideal line, for example a bearing axis from the shaft axis; may be due to machining, flexing of shaft or deformation of housing. and with a rigid surrounding structure. In axial bearings, a concentrically acting load ╳ Load which, for example, is to be supported at a friction point. Also strain from pressure and/or heat. See Contact surface is assumed. |

This simplified calculation cannot be applied to other bearing types. The displacement and rigidity ╳ Resistance to displacement under load in the elastic deformation area, dependent on bearing clearance and bearing type See Deflection at the operating point can be determined using the calculation program ╳ See INA EDP program BEARINX. |
