Principal dimensions

Needle roller bearings

Needle roller bearings are roller bearings with cylindrical rollers that are small in diameter. In spite of their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.

Needle roller bearings in different designs and a wide range of sizes, which are appropriate for different applications. In addition to customized designs, they comprise the following types and components:

– needle roller and cage assemblies (fig 1)

– drawn cup needle roller bearings

    with open ends (fig 2) and with a closed end (fig 3) full complement with open ends (fig 4)

– needle roller bearings with machined rings  

    with flanges (closure rings (fig 5) or integral flanges (fig 6)) on the outer ring, sealed (fig 7) or not sealed and with (fig 8) or without an inner ring (fig 9)

    without flanges on the outer ring (fig 10), not sealed and with or without an inner ring

– alignment needle roller bearings      

    with (fig 11) and without an inner ring (fig 12)

– inner rings for needle roller bearings (fig 13)

– universal joint bearings (fig 14)

– needle rollers

– combined needle roller bearings (separate section)  

   needle roller / angular contact ball bearings (fig 15)

   needle roller / thrust ball bearings (fig 16)

   needle roller / cylindrical roller thrust bearings (fig 17)

– needle roller thrust bearings and bearing washers (separate section)  

    needle roller and cage thrust assemblies (fig 18) and appropriate washers
