A typical application for spherical rollerbearings is the industrial winch of a traversing industrial lift. In this application the load, bending and deformation all call for rugged bearings that can function prop- erly even under misalignment.Open spherical bearing arrangementsprovided good service, but were too bulky and complicated to be considered completely satisfactory. As a result, the open bearings werereplaced with SKF sealed spherical roller bearings eliminating the need for the external seals and covers.This obviously saved space and alsomeant that the bearings could be posi- tioned 40 % closer to the drum, thus reducing the stress on the journals. In fact, it was possible to reduce the jour- nal diameter by 20 % and use smaller bearings.The new compact bearing arrange-ment requires much less maintenance and there is no loss of load lifting capac- ity. The result has been a 50 % savings of the total cost of the original bearing arrangement. 15
