Low- and medium-speed rolling mills
TQO bearings are directly mounted and comprised of two double inner races, two single and one double outer race, with an inner race
spacer and two outer race spacers.
Slots in the inner race spacer permit lubricant to flow from the bearing chamber to the roll neck. The inner race spacers are hardened to
minimize face wear.
