12.6 Elastic Deformation and Rigidity of Recirculating Units

The following charts show the elastic deformation characteristics of different types of recirculating units in connection with hardened tracks.

Elastic Deformation of Recirculating Unit Type SK

In connection with linear guideways type R or RD

Elastic deformation chart for Type SK recirculating unit

Elastic Deformation of Recirculating Unit Type SKD

In connection with linear guideways type R or RD

Elastic deformation chart for Type SKD recirculating unit

Elastic Deformation of Recirculating Unit Type SKC

In connection with linear guideways type R or RD

The total length of the straight lines applies for lubricated recirculating units, the dotted straight line for unlubricated ones.

Legend:

δ_A = Elastic deformation (µm)

P = Load (N)

These charts are used to determine the deformation of recirculating units under specific loads, which is critical for precision positioning applications.
