IKO Shell Type Needle Roller Bearings are lightweight
bearings with large load ratings. They employ
a shell type outer ring made from a thin special-steel
plate which is accurately drawn, carburized and
quenched, thus providing the lowest sectional height
among the needle roller bearings.
There are two types of bearings available in this
series; the caged type and the full complement type.
The appropriate type can be selected according to the
operating conditions. The caged type has a structure
in which the needle rollers are accurately guided by
the cage and thrust rings. It is useful for applications
at high-speed rotation. The full complement type needle
roller bearing, on the other hand, is suitable for
heavy-load applications at low-speed rotation.
Since these bearings are press-fitted into the housing,
no fixtures for axial positioning are needed. They are
ideal for use in mass-produced articles that require
economy, and have a wide variety of applications.
