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 installing.
• 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 (RNA22, NA22).
