Needle roller bearings with machined rings are made of high carbon chromium bearing steel. Needle roller bearings are available in various series and sizes or without ribs on the outer ring. Also available with or without inner ring.
In applications where less space is required, needle roller bearings offer very compact solutions.
Despite their low cross-sectional height, they have a high load-bearing capacity.
The possibility of assembling the inner and outer rings allows an interference fit of the shaft and housing respectively and can also facilitate maintenance inspections.
Needle roller bearings with machined rings have high stiffness due to their larger number of small diameter rollers.
Both the inner and outer rings have ribbed bearings, and needle roller bearings with machined rings can withstand axial displacement.
