Abstract

L'invenzione si riferisce a un cuscinetto a movimento lineare, che ha una rigidità estremamente elevata contro un carico dovuto a un momento, e una prestazione costante, ed è formato da una rotaia di guida e un cursore disposto sulla rotaia di guida, con un gran numero di sfere fra essi. Il cursore ha una forma a canale avente una porzione orizzontale e una coppia di parti a mantello estese dai lati opposti della porzione orizzontale. Ciascuna parte a mantello è dotata, sul suo lato interno, di una superficie di rotolamento delle sfere affacciata verso l'alto, e la parte orizzontale è dotata, in vicinanza della parte mediana del suo lato interno, di almeno due superfici di rotolamento delle sfere affacciate verso il basso.
