摘要
A bearing construction for idler rolls, and a maintenance method applicable to idler roll bearings, particularly useful for idler rolls which carry continuously cast strands in a multi-strand continuous-casting machine. The bearings are of softer metal than the roll necks, whereby wear takes place on the bearing surfaces, rather than on the roll necks. Wear on the bearing surfaces is concentrated within one lower quadrant of the central opening on the side toward which the load travels. The bearings are received in pillow blocks, but are shaped to be placed in four different positions within the pillow blocks throughout their life, whereby wear on each bearing is distributed among four areas. The different positions are obtained by inverting the bearings from their initial position within the pillow blocks, by turning them end-for-end, and by once more inverting them, or alternatively by rotating each bearing 90 DEG in its pillow block each time it is re-positioned.
