Abstract

A linear bearing comprising ball (3) circulation circuits in which the balls are supported by needles (2). Each circuit consists of passages forming the longitudinal section of the circuit and formed in two adjacent modules, said passages being connected at their ends by curved sections. The adjacent modules include support surfaces so they can be arranged next to each other. A projecting portion (23) is inserted into a longitudinal window (6) which is shaped to receive the needle (2) as well. The needle (2) is arranged in recesses (44 and 45), retains the balls in their circuits and holds the modules together. The modules are produced by injection in a mould having one slide acting in a single direction, whereas the balls and needles are components of a known kind.
