Needle roller and cage assemblies

What are the features and benefits of needle roller and cage assemblies?

In applications where space is limited, needle and cage assemblies offer the most compact bearing design solution. 

These assemblies require a housing bore which is suitable for use as an outer raceway and a shaft which can be used as an inner raceway. 

Benefits of needle roller and cage assemblies include:

• This assembly has the lowest cross-section of all roller bearings, making it ideal for applications which have extreme space limitations.

• Thanks to the large number of needle rollers, this assembly has an extremely high load carrying capacity.

• The large number of small diameter rollers means that this assembly has a high level of stiffness.
