Needle roller / thrust ball bearings
NKX series
Needle roller / thrust ball bearings in the NKX series combine a radial needle roller bearing and a thrust ball bearing based on the 511 series. They are able to support single-direction axial loads in addition to radial loads. They also permit relatively high-speed operation.
NKX .. Z series needle roller / thrust ball bearings are non-separable. They have a stamped steel cover that extends over the shaft washer of the thrust ball bearing. It is firmly attached to the housing washer that is integral to the needle roller bearing outer ring. The cover makes these bearings non-separable. Supplies the thrust ball bearing in this series filled as standard with a high-quality grease that has good rust inhibiting properties.
The cover which has no lubrication holes forms a gap-type seal with the shaft washer to retain the grease in the bearing.
