Abstract:
1. A linear rolling bearing for transmitting torques about its longitudinal axis, comprising: an inner profile element; an outer profile element which surrounds the inner profile element at least partially; the inner profile element and the outer profile element being mounted via rolling bodies such that the inner profile element and the outer profile element are displaceable with respect to one another in the longitudinal direction; the rolling bodies circulate endlessly in at least one first circulatory channel and in at least one second circulatory channel; each of the first and second circulatory channels having a loadbearing channel which is parallel to the longitudinal axis, a return channel which is parallel to the longitudinal axis, and two deflection channels which connect the loadbearing channel and the return channel to one another in an endless manner; the rolling bodies which are arranged in the loadbearing channel of the first circulatory channel being provided for transmitting a torque between the inner profile element and the outer profile element in a clockwise direction; the rolling bodies which are arranged in the loadbearing channel of the second circulatory channel being provided to transmit a torque between the inner profile element and the outer profile element in a counter clockwise direction, wherein the first circulatory channel and the second circulatory channel jointly transmitting torques in the same direction when either the return channel of the second circulatory channel becomes a loadbearing channel and loadbearing channel of the second circulatory channel becomes a return channel or the return channel of the first circulatory channel becomes a loadbearing channel and the loadbearing channel of the first circulatory channel becomes a return channel.
