needle roller thrust bearings are fitted with a form-stable cage to reliably guide and retaina large number of needle rollers. The diameter deviations of the rollers within one assembly are within 2µm,enabling these bearings to accom- modate heavy axial loads and shock loads. These bearings provide a high degree of stiff- ness within a minimum axial space. Inapplica- tions where the faces of adjacent machine com- ponents can serve as race ways,needle roller thrust bearings will take up no more space than a conventional thrust washer.They can accom- modate axial loads acting in one direction only. supplies needle roller thrust bearings in two designs:
