Surface force The pressure distribution on the guide rings is non-linear. The non-linear pres-
sure curve over the contact range was taken into account when calculating the permissible specific surface pressure. The permissible load on the guide strip is calculated by multiplying the projected area with the permissible specific surface pressure. However, the figure for the per-
missible specific surface pressure takes into account the possible angular offset of the piston when the recommended guide elements are used.
F F H F=P x A H=F / (d x P)H=guide strip width [mm]F=radial loading [N] A=projected area [mm˛] P=perm. compression per unit area [N/mm˛]d=rod diameter with rod guidance; piston diameter with piston guidance [mm]. © Freudenberg Simrit GmbH & Co.
