| Specification: | IKO Roller Followers are bearings designed for outer
ring rotation, in which needle rollers are incorporated
in a thick walled outer ring. Both crowned and cylindrical
outer rings are available. The outer rings run
directly on mating track surfaces, and the crowned
outer ring is effective in relieving the edge load
caused by mounting errors. The cylindrical outer ring,
on the other hand, has a large contact area with the
mating track surface and is suitable for applications
involving large loads or low track surface hardness.
In Roller Followers, there are two types of bearings
available, the caged type and the full complement
type. The caged type is useful for applications at
high-speed rotation. The full complement type, on the
other hand, is suitable for heavy-load applications at
low-speed rotation or oscillating motions.
Roller Followers include separable and non-separable
types. Also, in addition to the open type, shield type
and sealed type are available. The clearances
between the side plates and outer ring of the shield
type are narrow, and form labyrinths. In the sealed
type, special synthetic rubber seals are assembled in
these clearances, and they are effective in preventing
penetration of dust and dirt.
These bearings are available in a variety of types to
suit almost any kind of application. They are widely
used for cam mechanisms and for linear motions of
conveying equipment. |
