Radial needle roller and cage assemblies have a steel
cage that provides both inward and outward retention
for the needle rollers. The designs provide maximum
cage strength consistent with the inherent high load-
ratings of needle roller bearings.
Accurate guidance of the needle rollers by the cage
bars allows for operation at high speeds. Needle roller

These bearings are available with or without an inner
ring from 12 mm bore size. Standard complete bearings
type NA have an inner ring with convex raceway form.
If extra wide inner rings or rings with lubrication hole are
required, they should be ordered separately for use with
the corresponding RNA series.
Reference standards...

The rolling elements ot a thrust bearing are retained and
guided in radial pockets within the cage (1). The latter
is itself retained in relation to the plate (2) by means of
a steel ring (3). This assembly of parts is easy to handle
and install and provides a high axial load capacity whilst
occupying minimal...

A needle roller bearing is a bearing which uses small cylindrical rollers. They are used to reduce friction of a rotating surface.

Needle bearings have a large surface area that is in contact with the bearing outer surfaces compared to ball bearings. Additionally there is less added clearance (difference between the diameter of...
