Abstract
L'invention concerne les paliers pour mécanismes tournants. Un mécanisme tournant comporte notamment un arbre central 1 dont l'extrémité libre porte un plateau 4 muni d'un palier à charge axiale 6 de diamètre faible par rapport à celui du plateau, et un boîtier 3 qui est ajusté sur l'arbre, avec interposition d'un lubrifiant 5 entre eux. Application au montage des têtes tournantes des magnétoscopes portatifs.
