To provide a linear bearing with rotary bearings easily miniaturized and excelling in the coaxiality between the rotary bearings and linear bearing.
The linear bearing with the rotary bearings includes the linear bearing 11 formed by mounting a plurality of rolling elements 13 on the inner peripheral surface of an outer cylinder 12 whose outer diameter at both ends 12a, 12a is made relatively small, and a pair of annular rotary bearings 21, 21 disposed at the outer peripheral surfaces of the respective ends 12a of the outer cylinder of the linear bearing. Both ends 12a, 12a of the outer cylinder 12 are provided as separate bodies at an outer cylinder body part 12b between them, and the inner diameter of each end 12a is set smaller than the inner diameter of the body part 12b.
