<p>A high capacity and easy to maintain insert (40, 140, 200) for a cooling bed plate transfer grid (10). The insert supports a wide high capacity roller (42) in a grid pocket (48) modified by removal of a portion of a grid member (14) wherein the modified pocket has more than double the width. High capacity bearings (58) which receive the roller axle (62) are mounted in the frame (60), which is of modular construction to allow replacement of worn bearings as well as other repair and rebuilding easily. The insert is constructed so that it may be inverted to allow unworn portions of the bearings to experience axle contact whereby the bearing life is increased. In order that inserts may be installed or replaced at a remote location thereby requiring removal of the grid to the remote location, the height of the grid is adjustable. The roller height is set during initial insert installation so that, during a subsequent re-installation, which may be easily and quickly done in the field, there is advantageously no requirement for adjustment of the roller height.</p> |
