BEARING MOUNTING
Paul L. Haager, Canton, Ohio, assignor to The
Timken Roller Bearing Company, Canton,
Ohio, a corporation of Ohio
Application December 4, 1944, Serial No. 566,436
11 Claims. (Cl. 308-207)

This invention relates to bearing mountings,
particularly roller bearing mountings‘ for the
necks of the rolls of rolling mills.
The principal object of the present invention
is to devise a roller bearing mounting of the above
type that can be readily mounted in and removed
2
. in said box by a spacing ring 12 mounted in an
annular groove l3 therein at the adjacent ends
of said seats and by annular shoulders l4 at the
remote ends thereof.
The spacing ring l2 has
a notch L5 in the inner periphery thereof; and
lubricant passageways 56 lead from opposite ends
.of the bearing box C and open into said notch
from the windows of existing roll housings; that
through the side walls of the ring receiving
will accommodate the load occasioned by the roll
groove l3 for supplying lubricant to the bear
ing‘operation without sacri?cing the strength of
'
the roll neck; and that will permit ready removal 10 ing B.
