Backing bearings are roller bearings having a particularly thick-walled outer ring and can be mounted on stationary support shafts to form back-up or straightening rolls. The forces from the work rolls are transmitted via the support shaft and a system of support saddles to the roll or machine stands. fiona@ckfbearing.com Backing bearings are typically cylindrical roller bearings, with extra thick outer rings and handled in batches per shaft. Backing bearings are preferably handled as complete sets. fiona@ckfbearing.com In additional to the general remanufacturing process the set of backing bearings total radial cross section (wall thickness) is machined to achieve a very tight cross section variation of all bearings within the batch/shaft. The backing bearing remanufacturing process has been adapted from the general bearing remanufacturing process: regrind of the outer ring outside surface and refresh the logarithmic profile assemble, inspect and reclassify section height groups. SKF backing bearings for cluster mills are produced in many designs but are generally based on double or three-row cylindrical roller bearings. Single row needle roller bearing and double row tapered roller bearing designs are also available. The logarithmic contact profile between rollers and raceways produces a vastly improved stress distribution under all load conditions as well as when the bearing is misaligned under load. An optimised finish on all surfaces in contact serves to enhance lubrication conditions. As lubricant is supplied to the bearings via the support shaft, SKF backing bearings have lubrication holes and some have one or more annular grooves in the inner ring. fiona@ckfbearing.com
