<p>An improved wheel configuration is disclosed herein for use in a conveying system consisting of a solid wheel body (11) produced from a high temperature resistant hard wearing polymer material, the wheel body being carried rotatably on a shaft member (13, 28, 39, 46) which in turn is mounted from a support member (16) adapted to carry some desired object over a path defined by the conveying system, the shaft member (13, 28, 39, 46) and a retaining element (14, 45) forming a connection which defines a predetermined length of said shaft member on which the wheel body is carried without axial pressure being applied to said wheel body (11) such that rotation of said wheel body (11) would be impaired.</p> |
