Needle bearings
are roller bearings with cylindrical rollers which are thin
and long in relation to their diameter. They are referred to
as needle rollers. In spite of their low cross section the bearings
have a high load carrying capacity and are thus extremely suitable
for bearing arrangements where radial space is limited.
The range of needle bearings is extensive and, in addition
to customized designs, it comprises the following types: |
|
Needle
bearings
Needle roller and cage assemblies
Drawn cup needle bearings
Alignment needle bearings
Needle bearing inner rings
Needle rollers |

| Needle roller bearings have a high load carrying capacity in addition to their low cross-section and stiffness. They are especially suitable for bearing arrangements where radial space is limited. Because needle roller bearings only carry pure radial load and can not limit the axial displacement of shaft relative to the housing. It is important to ensure that inner ring axis and outer ring axis must be aligned during mounting the bearings. |
