Axial Combined Needle Roller Bearing NKX45

Specifications

  Axial combined needle roller bearing NKX45

Product details

 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 series

NKX series needle roller / thrust ball bearings do not have a cover around the thrust ball bearing. As a result, both the ball and cage assembly and shaft washer can be mounted separately from the rest of the bearing.

NKX .. Z series

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. We  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.

Lubrication

   For lubrication, the outer ring has a lubrication groove and lubrication holes. NX and NKX are lubricated with oil. The end cap in NX has lubrication holes. NX..-Z and NKX..-Z are lubricated with grease. The axial bearing component is greased using a lithium complex soap grease to GA08. The end caps do not have lubrication holes.
