IR 40X50X20
Inner ring for needle roller bearings, IR series, with lubrication feature
Inner rings with relubrication features for needle roller bearings are available as separate components. They 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. The inner rings in the IR series are the standard SKF inner rings for needle roller bearings. The inner ring contains a lubrication hole to facilitate relubrication.
