Needle roller bearing components

SKF supplies both inner rings for needle roller bearings and needle rollers as separate needle roller bearing components.
Inner rings are typically combined with needle roller and cage assemblies or drawn cup needle roller bearings in applications where the shaft cannot be hardened and ground.
Needle rollers can be used to design full complement bearing arrangements for low-speed or oscillating applications. These compact bearing arrangements have a very high load carrying capacity when compared to bearings with a cage and are economical, provided the shaft and housing bore can serve as raceways

Inner rings are available in two series:
-IR series
With or without a lubrication hole
With or without a machining allowance
-LR series

Needle rollers
-Are made of carbon chromium steel
-Have a hardness of 58 to 65 HRC
-Have a precision ground surface
