Profilschienen-Kugelumlaufführung

摘要

The invention relates to a rolling-bearing guideway with profiled rails in which the bending open of the guide legs of the carriage under load, as occurs in previously known designs, is greatly reduced and the losses of stiffness due to the bending open of the guide legs are thus minimised. It is possible to double the calculated service life, which is determined in accordance with DIN 636.
