Abstract: A molded bearing assembly for a molded wheel includes a synthetic resin outer bearing race element embedded in the hub of the molded wheel and having a cylindrical inner sliding, journal type bearing surface. An inner bearing assembly includes two molded synthetic resin bearing halves having continuous cylindrical outer bearing surfaces disposed within the outer bearing race in sliding engagement with the inner bearing surface of the outer race. The bearing halves of the inner bearing assembly abut each other at their inner ends and may include interlocking structural features at their inner ends that enable securing of the bearing halves together at their inner ends while presenting a continuous outer cylindrical bearing sliding surface that cooperates with the adjacent surface of the outer race. A wheel axle extends through the inner bearing assembly and supports the wheel and bearing assembly for rotation relative to a wheel support.

Abstract: A unique shaped paving block having a top face, bottom face and 18 flat sides that permits its ready placement by being rotated 60 degrees or less to orient with blocks already in position. The six groups of three exterior and interior sides or faces with an intermediate joining side face provides lock points so that the block is especially usable in high loading areas such as industrial applications and applications at airports.
