This roller follower is a bearing designed for
rotation of the outer ring. A needle roller and cage
assembly, an inner ring, and a face ring are
assembled in a thick-walled outer ring.
This bearing uses needle rollers as its rolling
element. It is available with a cage or full
complement roller bearing without cage. The outer
ring is guided axially by a face ring which is pressfitted
in the inner ring.
The outer ring is thick-walled type so that it is
resistible to high load and impact load.
The outer surface is available in both spherical
(crowning) profile and cylindrical profile.
The spherical outer ring is effective in damping
offset load which is caused by deviation in
The bearing with cylindrical outer ring is suitable
for cases of large load and low-hardness track
surface,due to its large area of contact with the
mating track surface.
This bearing is easier to handle because it needs
no mounting of a guide (thrust washer, etc.) on the
shaft unlike other types without axial guide
