To provide a direct drive bearing that can improve lubricity without using a complicated structure.

This compact direct drive bearing features that lubricant is hard to splash out and can be supplied due to the arrangement of a well- lubricated pipe 11 at a ball return pass 10. In addition, the well-lubricated pipe 11 arranged not at a load ball rolling part 7 but inside the ball return pass 10 has no effect of slide resistance to give the balls smooth motions.
