Needle Non Thrust Roller Bearings
Needle roller thrust 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 take up no more space than a conventional thrust washer.The needle roller bearing used in combined bearings has an annular groove with one lubrication hole in the outer ring. Needle roller / full complement thrust ball bearings in the NX series without the designation suffix Z have a cover with lubrication holes over the thrust part of the bearing.Most often they are oil lubricated.
Thrust Needle Roller Bearings Thrust needle bearings type comes in metric and inch designs. The cage & Needle roller assembly for the thrust needle bearing is a cage that has two pieces joined together, to which surface hardening is applied after the precision press processing of a steel plate, and in which high accuracy rollers are incorporated, in order to achieve rigidity and wear resistance.Axial needle roller bearings are construction units consisting of axial needle roller and cage assembles and thrust bearing washers with centering spigots. They can be combined with drawn cup needle roller bearings with open ends, drawn cup needle roller bearings with closed ends and needle roller bearings.
