Hydraulic linear motion bearings with integrated flow restrictors which eliminate the need for external compensation devices like capillaries or diaphragms, have been developed at the Fraunhofer IPT. This has been achieved by using of groove structures, only a few micrometers in depth, on the bearing surface. These structures produce their own, gap-dependent throttle effect.
