PURPOSE:To aim at preventing a roller from skewing and increasing a degree of load capacity, by making the barrel roller contact with a load roller transfer surface at the track block side so as to be crossed orthogonally with each other at a contact angle of almost nearly 45deg. to an inclined line passing the center of symmetrical jetties of the raceway track block. CONSTITUTION:A movable table 8 being almost U-shaped in its section is installed in position so as to straddle a raceway track block 1 having symmetrical jetties 2 and 3 extending toward an inclined line made up of a cross angle of nearly 45 deg. to a horizontal axis and using both these sides for load roller transfer surfaces 4-7. Each of concave grooves 11 and 12 is installed at inner surfaces of skirt parts 9 and 10 at both sides of the movable table 8, while each of bearing bodies 15 and 16 being almost square in its section is locked to these concave grooves 11 and 12 with a bolt 17. At the center of these side parts being orthogonal with the track block 1 of these bearing bodies 15 and 16, there are projectingly provided with oval guide jetties 18-21, and a barrel roller B1 to be transferred between these transfer surfaces 4-7 is set up on these load roller transfer surfaces 22-25 and held by cages 32 and 35. |
