ABSTRACT:
The invention relates to a guide element for unrestricted linear movement and/or rotary movement, involving ball-bearing contact on a shaft. The guide element comprises an external sleeve (1), ball-bearings (2) being arranged in circulation circuits (3) made in a tubular housing (4), the sleeve (1) having in its bore working sections (5) ensuring alternating contact between the ball-bearings (2) and shaft (7), and shallow disengagement sections (6) permitting recycling of the ball-bearings. The housing (4) is provided with at least six closed ball-bearing circulation circuits (3) arranged uniformly in equidistant pairs (13), the number of these pairs (13) of closed circuits (3) being half the number of the sections (5), and the two adjacent rectilinear sections of the two circuits of a pair (13) form an angle at the center smaller than and at most equal to the angle at the center of a section (5).
