Needle roller thrust bearings



    SKF needle roller thrust bearings are fitted with a form-stable cage to reliably guide and retain a large number of needle rollers. The diameter deviations of the rollers within one assembly are within 2 µm, enabling these bearings to accommodate heavy axial loads and shock loads. These bearings provide a high degree of stiffness within a minimum axial space. In applications where the faces of adjacent machine components can serve as raceways, needle roller thrust bearings will take up no more space than a conventional thrust washer. They can accommodate axial loads acting in one direction only.
    SKF supplies needle roller thrust bearings in two designs:
    • needle roller and cage thrust assemblies, AXK series (fig 1)
    • needle roller thrust bearings with a centring spigot, AXW series (fig 2)

    For applications where adjacent components cannot serve as raceways, the assemblies can also be combined with washers of various designs.
