Abstract:
A linear rolling bearing for transmission of torques about a central longitudinal axis, comprising an inner profiled element and an outer profiled element at least partly surrounding the inner profiled element, whereinthe inner and outer profiled elements are arranged for sliding relative to each other in longitudinal direction, the inner profiled element has a non-circular cross-section and at least two torque-transmitting, outwards oriented outer wall sections, at least one torque-transmitting inner wall section of the outer profiled element is associated to each outer wall section, the outer wall section and the inner wall section are mounted on each other by rolling elements, the rolling elements are guided in at least one rolling element circuit, the rolling element circuit guides the rolling elements in longitudinal direction of the linear rolling bearing in a first guide track through a loaded zone and thereafter, in a second guide track through a load-free zone, the rolling element circuit is formed in a cage arranged between the inner wall section and the outer wall section, at least one of the inner and the outer profiled elements comprising at least one biasing means acting on loaded rolling elements to create a play-free biasing of the inner and outer profiled elements against each other.
