Tapered roller thrust bearings of the double direction type are mainly used together with multi-row cylindrical roller bearings in rolling mill applications (fig 10). Those bearings with a plane shaft washer (fig 11) are the more popular as they are able to accommodate slight eccentricities of the shaft with respect to the housing bore, of the order of the radial internal clearance of the radial bearing with which they are used. A spacer sleeve is arranged between the two housing washers. This is dimensioned so that the cover screws of the chock can be fully tightened and no special spring adjustment of the bearing is required.
