PURPOSE:To both conveniently handle a bearing and reduce its cost, by forming lateral load ball track grooves and no-load ball guide holes to a laterally symmetrical position of the bearing to provide interchangeability of side caps. CONSTITUTION:In a bearing block 101 in which bearings are integrally formed to both sides, the bearing is constituted by a bearing main unit 105, holder 106 guiding plural balls and side cap. Load ball track grooves 109-112 and escape ball guide holes 113-116 are formed to this unit 105 while slits are parallelly formed respectively to an internal sloped side of the holder 106 covered to the main unit. While one of the external sloped sides of the holder 106 is fixed to a sloped surface of the bearing through a machine screw 131 and the other of the external sloped sides is fixedly calked to the sloped surface of the bearing. Further a direction changing U-groove guiding balls from the grooves 109-112 respectively to the holes 113-116 is formed to the side cap mounted to both end sides of the block 101. |
