Double direction tapered roller thrust bearings are mainly used together with double row cylindrical roller bearings or four-row cylindrical roller bearings in rolling mill applications.
Double direction tapered roller thrust bearings are available with a flat (plane) shaft washer or with tapered raceways on both the shaft and housing washers .
Double direction tapered roller thrust bearings variants with a flat shaft washer :
Double direction tapered roller thrust bearings can compensate minor eccentricity of the shaft relative to the housing bore - for example, to the extent of the internal clearance of the radial bearing.
Double direction tapered roller thrust bearings have a spacer sleeve between the two housing washers, which is designed so that the cover screws of the chock can be fully tightened and no springs are required.
 
Double direction tapered roller thrust bearings variants with tapered raceways on both washers:
Double direction tapered roller thrust bearings generally have a higher axial load carrying capacity compared with bearings with a flat shaft washer.
Double direction tapered roller thrust bearings can radially locate the shaft, to a certain extent.
Double direction tapered roller thrust bearings are available with a shaft washer that has one or two locating slots to prevent the shaft washer from rotating on its seat, because the bearings are usually mounted with a loose fit on the roll neck as well as in the chock.

If the load carrying capacity of double direction tapered roller thrust bearings is insufficient, a double row tapered roller bearing with a steep contact angle, for example in the TDIS design, could be an alternative.
