This roller follower is a bearing designed for rotation of the outer ring. A needle roller and cage assembly and a synthetic rubber seal reinforced with steel plate are assembled in a thick-walled outer ring.

• The outer ring, the needle roller and cage assembly, and the rubber seal are non-separable from each other.

• The outer ring is thick-walled type so that it is resistible to high load and impact load.

• A shaft must be provided with a thrust washer and a flange, because the outer ring has no ribs (or face ring) and no axial guide function.

• The outer surface is available in both spherical (crowning) profile and cylindrical profile.

• The spherical outer ring is effective in dampingoffset load which is caused by deviation in installing.

• The bearing with cylindrical outer ring is suitablefor cases of large load and low-hardness tracksurface,due to its large area of contact with the mating track surface.
