PULL-OUT GUIDE SYSTEM (1) FOR DRAWERS, HAVING A BASIC-STRUCTURE RAIL (2), A DRAWER RAIL (3) AND, IF APPROPRIATE, HAVING A CENTRE RAIL ARRANGED BETWEEN THESE TWO RAILS (2, 3). THE LOAD OF THE DRAWER IS TRANSMITTED BY WAY OF A FIRST ROLLING-CONTACT BODY (4) AND AT LEAST ONE SECOND ROLLING-CONTACT BODY (5A), AND THE FIRST ROLLING-CONTACT BODY (4) HAS A SMALLER DIAMETER THAN THE AT LEAST ONE SECOND ROLLING-CONTACT BODY (5A). THE DRAWER RAIL (3) IS DESIGNED SUCH THAT, WHEN THE DRAWER IS IN THE CLOSED STATE, THE FIRST ROLLING-CONTACT BODY (4) IS SUBJECTED TO LOADING BY THE DRAWER RAIL (3) AND, WHEN THE DRAWER IS OPENED, THE FIRST ROLLING-CONTACT BODY IS RELIEVED OF THE LOADING OF THE DRAWER RAIL (3).
