PURPOSE:To reduce assembly work by disposing rollers in two load grooves on the forward end side of the horizontal portion of a slide table and on the lower end side of the hanging portion thereof, and between the upper and side rolling surfaces of a track table. CONSTITUTION:A roller bearing comprises a slide table 1, a roller guide 4, a track table 5, and a lot of rollers 6 adapted to circulate in an endless track of a roller to apply a load between the slide table 1 and the raceway table 5. The slide table 1 is provided with a load groove 9, to which a groove-like no-load portion 10 corresponds. As the rollers are disposed in the load groove and between the upper and side rolling surfaces of the raceway table 5, the number of rolling surfaces can be reduced, and assembly work can be reduced. |
