PURPOSE:To bear both radiusward and thrustward loads by causing a cylindrical roller to be held in a mutually crossing manner by a rectangular roller transmission part formed by a V shape groove formed on both sides of a reaceway bed and the V shape groove formed on both internal sides of a slider body. CONSTITUTION:V shape grooves 2 and 2 are formed on both edge sides of a raceway bed 1 extending over its whole length. And a U shape slider body 3 spanned over the raceway bed 1 possesses bearing raceway parts 4 and 4 formed in a body in a protruded manner, and V shape grooves 6 and 6 which constitute roller transmission parts 5 and 5 having a rectangular cross section with each of the V grooves 2 and 2 of the raceway bed 1 are formed alongside a longitudinal direction on the interior sides of the bearing raceway parts 4 and 4. Then, return roller transmission parts 14 and 14 consisting of holes having a rectangular cross section which passes through in a longitudinal direction are formed on the bearing raceway parts 4 and 4, and cylindrical rollers are con-tained in both the transmission parts 5 and 14 so that the cylindrical rollers cross mutually with each other. |
