Rigidity

The roller element set with infinitely rigid surroundings and screw connection is calculated here. The calculated values serve as a cross-comparison between the individual roller bearing types and say nothing about the expected rigidity of the axis. These data can be requested from myonic in case of own modelling or calculation by the machine manufacturer.

A frequently-used calculation procedure which takes into account the deformation of the rings and the screw connection. The results are only directly comparable in case of application of exactly the same measuring points.

myonic procedure for the calculation, taking the following into account:
■ Normal adjacent constructions and screw connections according to the information in the product section
■ Normal preloads
■ Operating loads applied for the calculation

All product groups are based on identical FEM calculation methods with precisely defined parameters. This means that all stated rigidity values for the individual product groups (AXRY/AXDR/AXCR) are directly comparable.

Under-dimensioned or poorly-executed adjacent constructions substantially reduce the rigidity of the axis. Conversely, a better construction support for the bearing can also increase the rigidity.

In the AXRY series, the axial rigidity in the corresponding direction and the tilting rigidity can be increased with a whole-surface support of the L-section ring.

Depending on the thickness of the support ring, the tilting rigidity increases by up to 20%. You can find more about this in our product section.
