PROBLEM TO BE SOLVED: To provide a linear motion bearing with a rotary bearing which can be manufactured easily and make the linear movement and/or the rotary movement of the axial body with a high degree of accuracy. SOLUTION: The linear motion bearing with a rotary bearing includes a linear motion bearing (13) which accommodates the axial body (12) in a cylinder (11) non-rotatably and non-slidably and a plurality of rotary bearings (14) installed with at intervals along the longitudinal direction of the cylinder around the cylinder. The diameter of the peripheral face of the above cylinder is constant in the longitudinal direction of the cylinder, and the above rolling bearing comprises a circumferential groove (11a) formed on the outer peripheral face of the cylinder, a plurality of rolling bodies (15) arranged on this circumferential groove, an annular rolling body retainer (16) rotatably retaining the rolling bodies with part of them projecting to the outer peripheral side, an annular body (17) equipped with a peripheral groove (17a) to accommodate the part of the rolling body part projecting from the retainer on an inner circumference face.
