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 several designs:
–
needle roller and cage thrust assemblies, AXK series (fig)
–
needle roller thrust bearings with a centring spigot, AXW series (fig)
For applications where adjacent components cannot serve as raceways, the assemblies can also be combined with washers of various designs.
Again, there is insufficient information to answer your question. The trade-off between bearing types involves rotation, speed, load, shock, precision, allowable friction, cost, and lubrication (plus others that I have probably forgotten). There are a variety of turntable bearings available and you would do well to follow Guest 2's lead and contact an application engineer at SKF or possibly NTN.
