Abstract
A composite joint for a hydraulic system having two parts which rotate relative to each other is formed by the combination of a friction ring of hard material which is mechanically anchored to one of the relative rotating parts as a supporting collar around a ring of more flexible material mounted in a groove of the one part to exert a force on the ring of hard material providing with the joint a relatively large clearance between the two relatively rotating parts.
