NTN 6203lua Bearing
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 and, therefore, SKF supplies these bearings without grease.
