bearing assembly for use in supporting the roll
necks of the rolls used in rolling mills and the
like.
One object of the present invention is to pro
vide a bearing assembly for roll necks of this
type in which a self-aligning spherical roller
type bearing is employed to accommodate the

The cage assembly also preferably includes lon

joined to the transversely extending ends con
taining the rollers 22, as clearly shown in Figure

means of the retaining screw 23. The retaining

which the springs perform no particdlar func

within the'assembly.
One such assembly is located on either side of
the member 5 and it will be noted that by the po

the .self-aligning bearing assembly 1, is free to 25
