Abstract

Oil film bearings have been successfully used on backup roll bearings for decades. There have been many improvements since their inception and today's bearings are significantly better than their predecessors, although the principles of operation are still the same. Improvements in materials and designs have increased bearing life and product quality. This paper examines two areas of development made by DanOil bearings to improve bearing performance: 1. Mountingandlockingdevices-thisisprimarilyconcernedwith operational safety aspects of older bearings and the consistancy of mounting force. 2. Roll neck sealing - aimed at improving the operational characteristics, strip quality and seal life, resulting in cost savings.
