摘要:
A greaseless pivot center swivel and bearing device is provided. The device includes an outer housing having a sidewall with top and bottom portions, a top plate coupled with the top portion that includes an opening therein, and a bottom plate coupled with the bottom portion that includes an opening therein. The sidewall cooperates with the top and bottom plates to define an interior volume. A plurality of bushing members formed of a low-friction material are positioned within the interior volume and include a surface cylindrically curved about an axis extending between the top and bottom plates of the housing. The cylindrically curved surfaces cooperate with the openings in the top and bottom plates to define a cylindrical passage through the interior volume sized and shaped for receiving a cylindrical tube that rotates therein, e.g., a tube configured to connect with a water supply column of a mechanized irrigation system.
